Talking about farmhouses

Solar terms, phenology and proverbs divide the Earth's orbit (3600) into 24 arc segments, and every 150 is a solar term. So there are the following twenty-four solar terms: Spring rains startle the spring and clear the valley, summer is full and summer is full for two days, autumn is cold in Joan Hinton, and winter is snowy and snowy. Twenty-four solar terms can be divided into four categories, namely beginning of spring, vernal equinox, long summer, summer solstice, beginning of autumn, autumn equinox, beginning of winter and winter solstice. Five solar terms symbolizing temperature change: slight summer heat, great summer heat, summer heat, slight cold and great cold; Seven solar terms reflecting precipitation: rain, Grain Rain, white dew, cold dew, first frost, light snow and heavy snow; Four solar terms reflecting phenology or agricultural activities, such as fright, Qingming, Xiaoman and Mangzhong. The following is a solar term song circulating in the north: the early spring turns, and it rains along the Yanjiang River; Scared the crow to cry and dry at the vernal equinox; Qingming busy planting wheat, Grain Rain farming; The long summer goose feathers live, and the birds come to the whole; Mang seeds are shoveled, and cotton is not collected from summer to Sunday; It is not hot in the summer, but hot in the dog days; Beginning of autumn is busy playing indigo, and busy sharpening knives and sickles in summer; In the Millennium, there is no land in the autumn equinox; The frost has changed before the cold dew is cold; Beginning of winter fief, Xiaoxue River seal; Snow and water are closed, and the winter solstice is not allowed; A slight cold is not too cold, and a bad cold lasts for three or nine days. As can be seen from the quotation, solar terms are closely related to people's production and life. "When flowers and trees are in control, birds sing to report farming time." This is what people call phenology. Phenology refers to the activities of flowers, trees, birds and animals in nature according to certain seasons, which is closely related to climate change. Including three aspects: 1, germination, leaf spreading, flowering, yellow leaves and defoliation of various plants; 2. The arrival, initial singing, final singing, departure and hibernation of migratory birds, insects and other animals; 3. Some hydrometeorological phenomena, such as first frost, last frost, freezing, melting, first snow and first snow. In ancient China, five days was the waiting period and three days was the solar term. From winter to spring, from slight cold to Grain Rain, there are 24 seasons in the eight solar terms, and each season has a kind of flower. People call the wind blowing when flowers bloom "Hua Xinfeng", so it is called "Twenty-four Hua Xinfeng". In order to describe it accurately, people choose a plant with the most accurate flowering period as a representative among the plants that bloom in each of the 24 seasons, which is called Hua Xinfeng in this period. Slight cold: plum blossom, camellia, narcissus; Great cold: Daphne odora, orchid and alum in Phnom Penh; Beginning of spring: Spring Festival, cherry blossoms, spring; Rain: first-class cauliflower, second-class apricot flower, third-class plum flower; Surprise: waiting for peach blossoms, waiting for Tang Di, waiting for roses; Vernal equinox: once begonia, twice pear and three magnolia; Qingming: first-class tung flower, second-class wheat flower, third-class willow flower; Grain Rain: Once peony, twice mash and three times Donghua. Hua Xinfeng not only reflects the natural phenomena of flowering and seasonality, but also can be used to master the farming season and arrange farming. The following is a proverb about plant phenology summed up by working people in our country in production and life: peach blossoms are blooming, swallows are coming, and they are going to farm in the valley. Willow sprouts warmly, and the cold weather won't last long. The lotus is in bloom and sowing. The chrysanthemum is yellow and busy planting wheat. Tung blossoms, frost and snow no longer fall. Nine flowers bloom, and farm work comes together. Catkin is prosperous, and every family grows rice seedlings. Plums are golden, apricots are fat, durian is like fire, peaches and plums are falling, crops are flourishing, and the phenology of prosperity and harvest is the most direct language of nature. The appearance of migratory birds and insects clearly tells us the changes of seasons: the domestic swallow begins to see when it is startled, and beginning of winter flies south; Cicada started to sing when she was startled, and the Millennium never sang. Crickets sing at the beginning of Tomb-Sweeping Day and at the end of the autumnal equinox; Wild geese began to appear in Qingming, and the autumnal equinox was never seen before; Toads appear in Qingming, but the cold dew disappears; Frogs sing at the beginning of vernal equinox and at the end of autumnal equinox. There are also many proverbs about animal phenology: cats and dogs change their hair early, and it is already cold in winter. Thrush hides more grain and snows for a long time. Sparrows hoard food and it will snow. When the dog entered the kitchen, the snow arrived. Crocodile grass, the cold wave is coming. Frogs croak just in time to plant early rice. Cuckoo, cuckoo, growing grain and cutting wheat. The orioles sing, and the wheat needs to be cut. . When the toad comes out of the hole, it never stops raining. Earthworms climb the road, and it rains like hemp. Smell cicadas in the rain and announce the arrival of sunny days. Chickens stay late, ducks crow happily, and storms come quickly. It's going to rain in the ant nest. Swallows fly low, it's going to rain. Fish dive and rain comes. Turtle back tide, rain omen. The loach is quiet and sunny. The influence of meteorological activities on us can be described as meticulous, so people come to the conclusion that winter snow is a wheat quilt and Chun Xue is a wheat ghost. Mai covered the quilt three times and slept with steamed bread under his pillow. The winter solstice is full of frost, and it will be in Man Cang next year. When the frost is thick in winter, there must be a good sun. Spring frost does not stay overnight, it depends on staying overnight. The fog of the three dynasties sent the west wind, and if there was no west wind and rain, there was nothing. Spring fog is rainy and summer fog is hot, autumn fog turns cold and winter fog is snowy. The morning mist is closed, and the rising sun is available; The morning mist has not been collected, and the drizzle is endless. The fog is only three days, and it takes 38 days. The dew is heavy and the weather is fine. Frost and fog dried up the well. After first frost, the south wind continued to rain at night. Phenological phenomena have obvious zonal differences. "The spring breeze in the south of the Yangtze River is early, and the flowers in the north are late", which fully expresses the phenological differences between the north and the south of China. Peaches in Nanjing usually bloom on March 3 1, while peaches in Beijing will not bloom until April 19, with a difference of 19 days. The phenological phenomena in the east and west of China are also different. China's eastern coastal areas are later in spring and autumn than the inland areas. Because the ocean absorbs more heat from the sun, the warming rate is not as fast as that of land in spring, but in autumn, the heat radiation of seawater is slower, so the autumn in coastal areas comes later than that in the mainland. As far as Shandong is concerned, Yantai is on the coast and Jinan is inland. Every year, the apple trees in Yantai bloom more than half a month later than those in Jinan, just to avoid the cold in late spring, which is the reason for the bumper harvest of apples in Yantai. Autumn in Yantai is also later than that in Jinan, and apples mature for a longer time, which also makes Yantai apples more delicious. Because the average altitude rises by 100 m, the temperature drops by about 0.6℃. Generally speaking, the higher the altitude, the later the phenology. "In April, the beauty of the world is exhausted, and the peach blossoms in the mountain temples begin to bloom" is a description of this phenological difference. Mr. Zhu Kezhen is the founder of modern meteorology, climatology and geography in China, and has made important contributions to the development of geographical science. He is also the founder of China's "phenology". He insisted on phenological observation for decades, and his book Phenology played an important guiding role in agricultural production practice. Understanding and mastering phenology is a process of popularizing common sense, and it is also a good opportunity to train students to observe and understand nature.

1929 Don't reach out. You can't walk out in the morning glow on the ice in 3949. Wan Li Road, will the sunset glow be inserted? It's better to plant a kilo in July than to plant a kilo in July, and to plant a thousand manure fields in one grain instead of planting white rice in Qian Shan. It's cheating to eat too much without fertilizing the fields. It cheats you that buckwheat is not old without frost and wheat is not yellow without wind. If you want to get more grain, you can plant two kinds of sweet potatoes and rice, corn and mung beans, and the annual output is high, and you can see the seedlings in two hemp plants, the spring frost in three hemp plants, the summer carving and the spring competition. Before and after Grain Rain in summer, we planted melons and beans, but this winter wheat will not be harvested. Spring rain is as expensive as oil, and farmers are more worried. It rained three times in early spring, and rice was everywhere. The spring rain flooded and all the wheat and peas were lost. It rains in Tomb-Sweeping Day, and wheat and peas are everywhere. Wheat is afraid of clear skies and rainy nights. Summer rain kills rice, spring rain wheat disease. March rain is as expensive as oil; It rains in April, so it's easy to hoe the ground. There is no shortage of rice after the spring rain. It rained before and after in Tomb-Sweeping Day, and peas and wheat were picked. Money can't buy a drought in May and a full meal in June. There is a rain plow in spring and a thousand pounds of grain in autumn. It's cloudy in June, arachis duranensis. The spring rain flowed all over the street, and the wheat was harvested. It rains at night and sunny during the day, and there is no place to put food. A burst of sun and rain, planting yellow seedlings to eat white rice. There is no rain in the valley and no rice in the valley; There is much rain and rice in the valley. In the dog days, bend the millet under the soaking rain. Welfare is violent every day, sitting at home collecting rice. Autumn grain night rain is better than dung, and a night rain is fertilizer. It's autumn and it's raining there. When it rains in early autumn, everything is harvested. When it rains in summer, everything is gone. It rains in summer and there is rice in the barn. Summer, rain, rotten grain baskets. The temperature is sunny and hot in agriculture, and early rice must be good. If you don't take a fan in April, you are in a hurry to farm. Summer for autumn, no harvest. It is not hot in May, and rice does not grow. It is not hot in June, and the rice will not bear fruit. Cover June, there is grain but no rice. It's not hot in dog days, and the grain will not bear fruit. It's too hot to lie on the sidewalk. Only crops can be planted in the field. People are jumping in the house and rice is laughing in the field. People got into the house and rice flew about in the fields. People jump when they are hot, and laugh when they are hot. People are afraid of being old and poor, and rice is afraid of cold dew. The cold dew wind wiped out the harvest. Late rice grows in dog days. Autumn heat harvests late-maturing fields. Bitter worms in wheat can't be frozen. Freeze and break the wheat roots, and pick and break the hemp rope. Cold harvest of wheat, hot harvest of autumn. Snowfall and agriculture 12 In the snow is half a foot thick, and there is not enough wheat. Wheat seedlings are covered with snowflakes and will sleep with steamed bread in the coming year. It's snowing all over the sky, and next year will be a bumper harvest year. Snow piled up and wheat filled the house. It snowed heavily this winter and there will be a good harvest next year. Heavy snow indicates a good year. A winter snow, a fortune and a disaster in Chun Xue. A quilt in the winter snow, a knife from Chun Xue. Snow, like a quilt, froze Chun Xue to death. Winter snow is wheat quilt, and Chun Xue is rotten wheat root. Winter snow is a quilt, and Chun Xue is a ghost. When it snows a lot in winter, Chun Xue is useless. Chun Xue filled the ditch, but Xia Tian refused to accept it. Rivers of snow and water make the wheat thin. Chun Xue is a river, and everyone eats steamed bread with white flour. The seedlings are too cold to be rotten, and the seedlings are afraid of green frost when they come out of water. Cold hurts the roots, and frost begins. Mulberry leaves frost every night, raising silkworms. Late frost hurts cotton seedlings and early frost hurts cotton peaches. Cotton is afraid of cloudy days in August, and rice is afraid of cold dew and frost. Buckwheat is frosted and peeled. On the first day of August, the wild goose gate opens, and the foot is frosty. It's sunny after the cold wave, and there are no clouds in Wan Li at night. There is no dew in the north wind, but there is frost. Snowflakes, hail lines. The wind blew a large area, and the hail hit a line. Man Cang is a dry valley in spring and crops are cut off in summer. There is no drought in spring, and the drought in autumn is halved. Building houses in spring drought and grain shortage in autumn drought. Dry in polder fields is afraid of flooding, and flooded in mountains is afraid of dry. Not afraid of dry seeds, but afraid of dry autumn seedlings. Not afraid of seedlings drying up, but afraid of seeds drying up. Three years and two ends, skin and wall. It's good to plant polder fields, but plum rains worry. Polder fields are easy to build, but may is sad. The polder field became a famine year overnight. Lack of water head, drought lack of tail. A hundred days of water shortage, a year of drought. Water shortage is a front line, and drought is a large area. The drought and flood are scheduled for July 15, and the harvest is scheduled for August 15. Phenology and agriculture (predicting agricultural time by indicating crops) When all the flowers are in full bloom, farm work comes together. Poplar leaves clap their hands, and the old man presses the melon seedlings. Poplar leaves are flapping and sorghum is planted everywhere. Poplar leaves are rich and melons are planted quickly; Yang, plant watermelons quickly. Poplar leaves are as big as money and cotton is planted everywhere. Poplar leaves are abundant, so it is necessary to grow cucumbers. Fly to Yang Shuhua to grow cotton. Catkin is raised and sorghum is planted. Willow blossoms, beans grow and melons grow. Catkin is prosperous, and every family grows rice seedlings. When the willow buds twist, the yam is buried. Catkin falls and yam is planted. Catkin fell to the ground and cotton was born. The horseshoe with tung leaves is big, and the rice seeds are not worried about mud. Tung trees are blooming and sesame seeds are sowing. Tung flowers fall to the ground, peanuts can't be planted. Tung flowers fall to the ground, and the valley plants mud. Toona sinensis bud drum, planting. Toona sinensis germinates to grow cotton. Toona sinensis, grab it. Every household grows cotton. Toona sinensis is big, put the seedlings down. Jujube trees germinate and grow cotton. Jujube bamboo shoots, sesame melons. Jujube plugs the nose and carries beans on his legs. Jujube belly, sickle sharpens the grain. Elm hangs money and can grow cotton. I have been planting sweet potatoes for thousands of years. Yu Qian shua shua, sorghum seed shua. Money is yellow and food is busy; Poplar catkins are planted in mountain classics. Peach blossoms bloom, plum blossoms fall, and seeds are fine. Peach blossoms bloom, apricot blossoms decline, and plum blossoms sell leeks. Peach trees blossom and melons grow in the fields. Peach blossoms fell to the ground and beans fell to the mud. Till early and plant early. When the flowers bloom, the valley comes out. I feel numb when I pull out the flowers. Qilihua, go home and sow seedlings. Starching barley and planting it quickly. Persimmons germinate to grow cotton. Wheat flower, cucumber steak. Seedlings sway and peanuts are planted. Bamboo shoots have scales, so don't ask your mother when you hatch silkworms. On April 8, amaranth was pinched, and people in the four townships transplanted rice. In the fourth month, the south wind blew the yellow barley plain, and only sericulture and rice were planted. Lotus leaves are as big as money, and cotton is planted everywhere. Lotus, plow and rake; The lotus is in bloom and sowing. The chrysanthemum is yellow and busy planting wheat. When the fruit turns black, cut the barley. Wheat yellow apricot, bean yellow crab. Loquat blooms and eats persimmon, and persimmon blooms and eats loquat. Papaya blossoms to plant adzuki beans, and adzuki beans bloom to harvest papaya. Sorghum is ripe and rice is harvested. Predict the distribution of grain in agricultural season with indicator animals as indicators, and sow grain quickly. Turtledove cooing, this swish. Toad knocks, and every family soaks grain. Frogs croak just in time to plant early rice. Frogs croak just in time to plant early rice. Frogs play drums and beans fall to the ground. Silkworms cocoon and transplant seedlings quickly. The old silkworm chess piece is black and ready to cut barley. Mosquitoes see blood, but wheat sees iron. The orioles sing, and the wheat needs to be cut. When cicadas sing, cut early rice. It's too late to plant beans. Litchi is ripe when cicadas sing. The oriole came to pull the garlic bolt; When the oriole left, the sweet potato came out. Swallows come to plant amaranth. Xiaoyan comes, destroys seedlings, Xiaoyan goes, and rice soup is fragrant. Xiaoyan came, smoked garlic seedlings; Wild geese come to pull cotton and firewood. Wild geese come to grow wheat. Never mind growing wheat. The breath in the mouth, the wheat in the field. Fertilizers and agricultural fertilizers Building a flower of a crop depends entirely on fertilizers. Manure is the treasure of the farm, and crops can't grow well without it. Farming is not a coincidence. Manure is the treasure of crops. Dung is a tiger in the soil, which can increase one stone and five. Manure is the treasure of crops, and it can't grow without it. There are no ghosts in farming, relying on dung and water. Dung grass dung grass, the treasure of crops. Farming is not a coincidence, and manure is everywhere. Crops should be good and fertilizers should be full. Don't ask in the farmer's field, nothing but rain is dung. Farm work, don't ask, except work is shit. Don't ask about farming, deep ploughing and applying more manure. There is more manure in farming and more millet baskets. Too much water makes a river, and too much dung makes food. People live on food, and the land lives on dung. People depend on food, and the land depends on dung. People depend on food, and fields depend on fertilizer. People need food, and rice needs to gain weight. Man is the power of food, and land is fertile soil. People weave longan and candied dates, and people weave river mud and dung grass. The land is raised by people, and the seedlings grow by dung. Birds depend on trees, fish depend on rivers, and crops look much fatter. Fish live by water, and seedlings grow by dung. There is enough oil to shine, and enough fat to be strong. There is more light in the lamp and more grain in the field. More firewood, higher flames and better manure. Eat with a long mouth and grow fat with a long root. Oil is food, salt is power, and crops depend on time and dung. Grain is born in soil, and soil and fertilizer have a good harvest. Gold medal in millet dung contest, Pearl Buck in sorghum dung contest. The ground is full of dung, and food is piled up like a mountain. People don't lose their land, and the land doesn't lose their stomachs. Don't stick to crops, every dung is the same. Thousands of loads of dung go down to the ground and thousands of loads of grain go down to the warehouse. A fertilizer, a grain; Very fat, cereal Man Cang. With a dunghill mountain, I don't know anything about rice river and grain river. Spring is rich, and the valley in autumn is Man Cang. Spring manure is dense, and autumn grain is spread. Apply 1000 loads of fertilizer in spring and 10000 loads of grain in autumn. Winter is better than dung heap, and next year is better than grain heap. There will be dung this year and food next year. A variety of manure is not as good as planting it skillfully. It is better to sow seeds skillfully than to be a lazy person. More fat destroys grain, more firewood puts out fire. Spoiled children, withered rice grew in the fertile fields. Lack of fat yellow, fat down. Seeds can't be planted in white ground, and seedlings can't be planted in white water. It is difficult to cultivate without fertilizer and fight without food. Farming without fertilization is just messing around. Farming without fertilization is a waste of time. There is no manure in the good field every other year, and the crops grow badly. Rice grows in fertile fields and grass grows in thin fields. Without fertilizer, there is no rice. Millet spikelets have no dung, millet has no dung. Rice can't get dung, so I hate God for nothing. It is difficult to cook without firewood at the bottom of the pot, and it is difficult to increase production without manure in the field. There is no rice in the early morning jar, and it is not fat to grow rice in the field. People are hungry if they don't eat. There is no dung on the ground and they eat less. A lamp is not lit without oil, and rice is not long without fat. Yellow people are sick, and yellow seedlings lack feces. Farming needs no dung, and the blind need no sticks. If you want to have a good harvest, you have to dig mud residue and wring lake grass. Fertilizer is everywhere. I'm afraid I won't do it. Grass becomes dung, and the longer it grows, the stronger it becomes. If you want to get more grain, you should always accumulate fertilizer. The accumulation of fertilizer is like the accumulation of grain. Man Cang is rich in food. Grass is neither rotten nor muddy, and mud is neither grass nor fat. Winter grass is fertile, and spring grass is fertile. Mud, beans and safflower in the pond are the three treasures of farmers' farming. Pig manure safflower, farmers two treasures. If the grass sits on the head, the fertilizer will not worry. Gold can't buy rain dung. Crops pout when manure is not poured. Where there is water, there is fat, and without water, there is no fat. River mud as the base and pig manure as the root. Ash and dung are used as bases, and water and dung drop. Layered manure, full of food. Fertile fields in winter and fertile seedlings in spring. Don't put too much dung, just water it with trees. Money is hard to buy top seedling dung. People are afraid of being thin in the womb, and young people are afraid that their roots are not fat. It is best to soak the roots of seedlings in a lot of feces. It is better to fertilize a large area than to pay some money. The power of dung is concentrated, and its power is infinite. The soil should be improved and the base fertilizer should be full. It is profitable to spread manure to raise land and level manure now. Dung is not smelly or strong, and crops are not black or prosperous. Dung is buried, and one acre is worth two acres. Good fertilizer and full crops. Water and fertilizer come to the moon, and compost is hot. Fecal growth, no hope; When the manure is cooked, the grain is Man Cang. People avoid growing and vegetables avoid getting fat. Cold manure, fruit trees and hot manure vegetables have root rings attached to raw manure. Chicken manure has high fertilizer efficiency and will not cause fever and death of seedlings. That year, sheep manure was abundant, and pig manure flourished every year. One season of fat mud, two seasons of strength. Pig manure, sheep manure, cow manure and horse manure followed closely. When the pond sludge reaches the ground, it will be treated for two or three years. Fertilizer efficiency is slow, and stratification should be sufficient. Cow dung is cold, horse dung is hot, and sheep dung is not bad anywhere. Get momentum on dung and hoe the ground. All fertilizers should be mixed, not mixed at will. Seedlings with insufficient base fertilizer will not grow long, and seedlings with insufficient topdressing will not flourish. Gold as base fertilizer and silver as topdressing are fatter than smart fertilizer. If the crops grow well, they should be fertilized in time. Reasonable manure, full. Farming is not clever, as long as the fertilizer is well matched. If you want the crops to flourish, fertilize them reasonably. Fertilizer is the treasure of crops, and it is skillful to apply it adequately. Crops should be good, and fertilization should be clever. Endless Yangtze River water, endless farm manure. Inexhaustible seawater and fertilizer. The rice field is covered with three layers of straw, which is more delicious than the lard bowl. The earlier the rice is poured, the better the early rice is. Returning straw to the field is worth two years a year. High-cut rice is deep in the field and harvested with chemical fertilizer for three years. Top dressing before the rain, one punch a night. Rice needs river mud and wheat needs manure. Sesame cake beans, bean cake flowers, and ground ash grow sweet potatoes. Cake fat wheat sheep dung valley, dung sorghum grows thick. Donkey dung millet sheep dung wheat, dung corn, kang soil yam. Cotton is on ashes, melon is on shit. Water the flowers with wheat and bean sprouts. Bagu grabs a handful of dung, and the longer it grows, the stronger it becomes. Fertilization should not be early, and millet grows well. Wheat seedling manure and base fertilizer. Wheat covered with dung is covered with dung. Wheat is abundant in the womb, but feces are unreliable. The wheat rolled in the ash and the harvest was stable. Three pursuits are not as good as one bottom, and years are not as good as years. It is not as good as covering the bottom outside the year. Give the wheat a lamp before the New Year and a load after the New Year. If you want leek, look for it in the ash. Potatoes are well grey, big and high quality. Broad beans don't need dung, as long as they are trapped in ash. Broad beans are a handful of ash, and the horns are piled up. Tiles are made from blanks, and sweet potatoes are planted from ashes. It is not a coincidence to grow hemp. We should be diligent in weeding with water and feces. There is no coincidence in growing hemp, as long as you are full in winter. There are two sheds of grass and flowers, just going to plow and rake in the field. Flowers and plants, fertilizer to households. Seed and agricultural seed construction should be good for children, good for planting, and a variety of food. Good flowers bear good fruit and good plants grow good rice. Good seedlings will plant, and good flowers will bear good peaches. Plant good seedlings and saw good gourds. What seeds, what seedlings, what gourds, what gourds. The plant is not good, the seedling is not straight, and a gourd is crooked. Three years of good things will change if you don't choose. A grain of miscellaneous grains is not too small, and it will not be picked for three years. If we don't choose seeds for three years, we won't be able to increase production. If you don't choose to farm, you will be exhausted. If the seeds are impure, people will die. If the seeds are not good, it is difficult to guarantee the harvest. Seeds are bought cheaply, and the open space is large. Good seeds produce good seedlings, and bad seeds produce barnyard grass. If the seeds are not selected properly, barnyard grass will grow all over the field. A thousand calculations are not as good as a good variety. The grain is not adjusted and the harvest is not good. Seed selection every year, the output is increasing. The more fanning the flames, the stronger the species. Always choose the seeds of grain and forge the mill forever. If you change rice seeds, you will have extra rice. Adjusting wheat seeds is like feeding them again. Good planting of stubble fertilizer. Choose good seeds to plant, with two ridges at the top of one ridge. Look at the fields, choose the seeds, look at the fields. One is quality, and the other is quantity. Don't be fooled by seed selection in the field. Picking in the field, choosing in the field, busy for a long time, sweet for a year. Seeds are afraid of floating on the water, and grains are afraid of bending. Home selection is better than field selection, and field selection is better than washing. Choosing a field is not as good as choosing a field. Choosing a field requires selecting grains. When the seeds pass through the fan, the inferior seeds are easy to see. Seedlings grow well after screening. The seeds are round and the roots of the seedlings are strong. I'd rather go hungry than stop growing grain. Choosing seeds is a coincidence, and a big ear is full of particles. Clever seed selection, big and full ears. Three thousand grains, sixty wheat and eight hundred sorghum are good. Three thousand grains, sixty wheat, good peas and eight seeds. Wheat has a short stem and a long beanstalk. Wheat has short stems and beans have long spikes. Good grain has no ears, and good wheat has no leaves. Choose a stick and stick the gun in your waist. Drop both ends, plant in the middle, and the corn cob will not be sharp enough. Sorghum should be sharp and corn should be medium. Rice is full of water and has round grains. Tian Tian, good experience, busy for a while, sweet for a year. Seeds are kept every other year, so don't worry about sowing time. Millet yellow, choose seeds to hide. Corn will go bad in winter if it is not dried. A bucket of seeds is better than a bucket of gold.
