Based on the 24 solar terms song, talk about the relationship between the 24 solar terms and agricultural production!

The beginning of spring: literally means the beginning of spring. The plan of the year begins in spring. This is the time of year when farm work begins to get busy. Plants and all things revive and start to grow. Farmers remove weeds, store fertilizers, clear ditches, drain water and prevent stains to promote the growth of crops.

Rain: The weather gradually warms up, the ice and snow melt, the air becomes moist, and rainfall begins and increases. Commonly known as: Rain in spring is as precious as oil. Crops grow rapidly under the water of rain at this time. At the same time, a spring production work plan is formulated.

The Waking of Insects: The spring thunder begins, the weather is clear and the climate is warm, awakening hibernating animals underground to emerge and move, and trees begin to take root and sprout. This is the best time for fruit grafting, early rice seedlings, and tree planting.

Spring Equinox: The warm spring has arrived, and the days and nights are of equal length. Farmers pay attention to the management of field fertilizer and water in the middle and late stages of spring crops, plow the winter fallow fields, prepare seeds, fertilizers, agricultural film and other agricultural production materials, prepare for spring plowing, and plant trees to improve and protect the ecological environment and regulate the climate.

Qingming: The weather is refreshing and warm, and the grass and trees are beginning to sprout new branches and buds. It is the best time to go out in spring, and to visit the tombs during spring outings in the countryside. The whole country has entered the busy farming season. Early and mid-season rice are sown successively, wheat is jointing, and rapeseed is blooming. Field management cannot be relaxed.

Grain Rain: Rainfall is heavy and lasts for a long time, which promotes the rapid growth of cereal crops. Farmers are raising rice seedlings, sowing corn early, and preparing for spring plowing. Nong Yan has a saying that "a severe drought will not last until May 13th". If there is no rainfall or less rainfall from rain to Grain Rain, it is a sign of drought, so prepare in advance.

The beginning of summer: the beginning of summer, the new summer is coming, and everything is prosperous. Due to China's vast territory and diverse geographical and climatic factors, Lixia mainly refers to the area south of the Yellow River. Spring flowering crops have entered the yellow-ripening stage and can be harvested in time for clear weather. The Jiangsu and Zhejiang regions are about to enter the rainy season, and the Meiyu flood season has begun. It is necessary to be prepared for flood prevention. In continuous rainy weather, we must be careful to prevent sprouts and mildew in the early spring harvests, and we must also do a good job in drought resistance and seedling preservation.

Xiaoman: The grains of wheat crops are beginning to be full but not yet mature. Farmers harvest spring crops, sow soybeans, corn and other spring crops in large areas, and plant rice, entering the busy farming season.

Grandgrass: The season for busy harvesting and planting of summer-ripened and summer-sown crops. Wheat, barley and other awny crops have matured, and the intense summer harvest has begun. At the same time, it is also the busier season for summer planting, so it is also called Miscanthus. "Busy planting". When it comes to the awn planting season, the mid-season rice that has not been transplanted should be transplanted as soon as possible; if it is delayed further, the vegetative growth period of rice will be shortened due to the increase in temperature, and the growth stage will be prone to drought, diseases and insect pests, and the yield will not be high. This is the meaning of the farmer's proverb "Earns are planted in a hurry".

Summer Solstice: The hot summer is coming, the day with the longest day and the shortest night in our country. Drought conditions will occur in some areas. In order to enhance drought resistance and achieve a bumper agricultural harvest, in these areas, storing rainwater before the rainstorm is an important measure. At the same time, mosquitoes, rats and ants are active in summer, so it is necessary to strengthen summer field management, clear weeds in time, and prevent and control diseases and pests.

Slight Heat: The climate is dominated by high temperatures and little rain. The climate is getting hotter and hotter, and the summer heat is rising. Facing the transitional period between plum floods and droughts, farmers in various places are strengthening water storage and drought prevention while doing a good job in flood prevention, striving to achieve both flood prevention and drought relief.

Great Heat: The hottest period of the year, with most areas experiencing scorching heat. Farmers pay close attention to cultivating and weeding spring crops, managing fertilizer and water in fields, and preventing and controlling diseases and insect pests. Crops that love warm temperatures reach their peak growth rate. Management of water and fertilizer fields must be strengthened. Late rice transplanting should be done before the beginning of autumn.

Beginning of Autumn: The cool autumn begins, the hot summer slowly recedes, and the temperature begins to drop. Late rice requires cultivating and weeding, and irrigation is required when drought occurs. Autumn sowing should be carried out quickly. Picking the tops of cotton promotes the development of autumn cotton.

Sushu: The hot summer is over. Late rice is in a critical period of growth. In order to ensure farmland water use in winter and spring, water storage work should be done carefully during this period. This is the busy season for harvesting mid-season rice in the basin.

Bailu: The temperature drops significantly, the weather turns cooler, continuous rain begins, and the sunshine hours become shorter. Actively adopt corresponding agricultural technical measures to reduce or avoid the damage of autumn rain. In addition, we should seize the opportunity to store water when it rains.

Cotton is picked in batches, and field management of autumn corn and other crops is strengthened in the later period. Do a good job in sowing buckwheat and other late autumn crops.

Autumnal Equinox: marks the beginning of autumn, when the air is crisp and clear. It is commonly known as "autumn rain and coolness", when cold air comes. In terms of crops, we will continue to do a good job in late rice field management. Cotton selection and harvesting. Winter wheat and rapeseed are ready for sowing. At the same time, we must pay attention to harvesting sunshine, managing moisture and preventing stains, and ensuring the quality and progress of production during the "Three Autumn Periods". Make full use of the meteorological conditions of autumn with little rain and light and good soil moisture, seize the opportunity to carry out afforestation, and strive to increase the survival rate of saplings.

Cold dew: The temperature drops, the vegetation gradually withers, and the weather turns cooler and colder. This is the suitable period for sowing rapeseed in the Yangtze River Basin, and winter wheat sowing in the Jiangbei region. Agricultural production requires harvesting and sowing on sunny days; on the other hand, it is also necessary to adapt to local conditions and adopt various effective farming measures such as deep trenches and high compartments to reduce moisture damage and improve the quality of sowing.

Frost: The weather is cold and frost begins. This is the harvest season for spring crops. In terms of production, farmers should be guided to harvest in a timely manner, then plow the farmland, sow the early spring crops, and use mulch to cover and increase the temperature to ensure the smooth growth of the early spring crops.

The beginning of winter: Winter begins here. Climatic conditions are suitable for rapeseed transplanting. Wheat with a short growth period and strong spring characteristics should also be sown early, because there are often strong cold air invasions in the late Beginning of Winter, and the temperature often drops significantly. If the temperature after sowing is low, the emergence of seedlings is slow, and the growth rate is insufficient, it will affect the growth of wheat. Yield. Harvest and dry late rice well. Do a good job in finishing the winter wheat sowing.

Light snow: The temperature drops rapidly, and it usually begins to snow in the Yellow River Basin, entering the snow season. To prevent frost damage to crops, livestock should also be protected from cold and warm.

Heavy snow: The amount of snowfall increases and there is snow on the ground. The low temperature of snow water can freeze to death overwintering pests on the surface, which also brings benefits to agricultural production. But it is also necessary to strengthen field management of spring flowering crops such as winter wheat and rapeseed.

Winter Solstice: Strong cold air marks the approach of cold winter and the arrival of cold winter. In terms of agricultural production, we will strengthen the management of fertilizer and water for early spring crops, focusing on frost prevention. It is also the slack season for farming, so I do the work of collecting farmyard manure during my leisure time.

Xiaohan: The climate is cold and the temperature is low. Accumulate manure, make fertilizer, clean up water conservancy projects, start greening and planting trees, clean and renovate fish ponds.

Big Cold: The coldest time of the year. The activity of agricultural production activities has dropped significantly, mainly in preparation for rest and planting plans for the coming year.
