Talking about the transformation of oxidation pond

Beginning of spring: Literally, it means the beginning of spring. The plan of the year lies in spring, which is the busiest time of the year for farm work. All plants revive and germinate, farmers weed, collect fertilizers, clear ditches and drain water to prevent waterlogging and promote crop growth.

Rain: The weather gets warmer, the snow melts, the air is moist, it begins to rain, and the rainfall increases. Commonly known as: rain and spring rain are as expensive as oil. At this time, the crops grew rapidly under the rain, and at the same time, Da Chun made a production work plan.

Surprise: Spring thunder began to sound, the weather was fine and the climate was warm. Animals hibernating underground were awakened to the excavation activities, and trees began to take root and sprout. This time is the best time for fruit grafting, and early rice is ready to raise seedlings and plant trees.

Equinox: Spring with warm climate has arrived, and the time between day and night is equal. Farmers should do a good job in field fertilizer and water management in the middle and late stages of spring sowing crops, plough fields in winter leisure, prepare enough agricultural production materials such as seeds, fertilizers and plastic films, plant trees, improve and protect the ecological environment and adjust the climate.

Qingming: The weather is fresh and warm, and plants are sprouting new branches. Stepping into spring is the best time, and a spring outing in the suburbs is to sweep graves. The whole country has entered the busy agricultural season, with early and middle rice sown one after another, wheat jointing and rape flowering, and field management cannot be relaxed.

Grain Rain: Heavy rainfall and long time have promoted the rapid growth of cereal crops. Farmers enter rice seedling raising, sow corn early and prepare for spring ploughing. There is a saying in agricultural proverbs that "the drought will not reach May 13th". If there is no rain or little rain in Grain Rain, it is a sign of drought, so we should make preparations in advance.

Changxia: With the beginning of summer, a new summer is coming, and everything is thriving. Because of China's vast land area and different geographical and climatic factors, long summer mainly refers to the area south of the Yellow River. In spring, flower crops enter the yellow maturity stage and are harvested in time. Jiangsu and Zhejiang will enter the rainy season, and the rainy season is about to begin, so we should prepare for flood control. Even in rainy weather, we should guard against germination and mildew of Koharu harvest and do a good job in drought resistance and seedling protection.

Xiaoman: The grain of wheat crops is full and immature. In Koharu, farmers harvested crops, sowed soybeans, corn and other large-scale spring crops, planted rice, and began to enter the busy farming season.

Ear seed: the season when summer-ripe and summer-sown crops are busy harvesting and sowing. Wheat, barley and other crops with awns have matured, and the intense summer harvest has begun. At the same time, it is also a busy season for summer sowing, so ear planting is also called "busy planting". In the season of awning, mid-season rice that has not been transplanted should be planted quickly; If it is postponed again, the vegetative growth period of rice will be shortened due to the increase of temperature, and the growth period will be easily affected by drought and diseases and insect pests, and the yield will not be high. This is the truth of the agricultural proverb "busy planting".

Summer solstice: With the arrival of hot summer, China has the longest day and the shortest night. Some areas will be dry. In order to enhance drought resistance and win a bumper harvest in agriculture, it is an important measure to store rainwater in these areas. At the same time, mosquitoes, rats and ants are active in summer, so it is necessary to strengthen field management in summer, remove weeds in time and prevent pests and diseases.

Slight summer heat: the climate is dominated by high temperature and little rain, the climate is getting hotter and hotter, and the summer heat is rising. In the face of the turning point of Mei's flood and drought, farmers are doing a good job in flood control, strengthening water storage and drought prevention, and striving to achieve both flood control and drought prevention.

Great summer: the hottest period of the year, with intense heat in most areas. Farmers should do a good job in intertillage weeding, field fertilizer and water management, and pest control in Da Chun. Thermophilic crops, the growth rate reached its peak. It is necessary to strengthen the management of water and fertilizer in the field. Late rice should be transplanted before beginning of autumn.

Beginning of autumn: The cool autumn begins, the hot summer slowly recedes, and the temperature begins to drop. Late rice needs intertillage weeding and irrigation to prevent drought. Grasp the autumn sowing. Cotton topping promotes the development of autumn cotton.

Summer: The hot summer has passed. Late rice is in a critical period of growth. In order to ensure the water supply of farmland in winter and spring, water storage should be done well during this period. Basin is a busy season for harvesting mid-season rice.

Millennium: The temperature dropped obviously, the weather turned cold, it began to rain in Mao Mao, and the sunshine time became shorter. Actively take corresponding agricultural technical measures to reduce or avoid the harm of autumn rain. In addition, we should catch rainwater to store water. Cotton is picked in batches, and the field management of autumn corn and other crops is strengthened in the later stage. Sow buckwheat and other late autumn crops.

Autumnal Equinox: It marks the beginning of autumn, commonly known as "an autumn rain and a cold", and cold air strikes. In terms of crops, we will continue to do a good job in field management of late rice. Cotton seed selection and flower picking. Winter wheat and rape should be prepared before sowing. At the same time, we should pay attention to clearing the sun, controlling soil moisture and preventing waterlogging, and do a good job in the quality and progress of production in Sanqiu. Make full use of the meteorological conditions with less rain and good soil moisture in autumn, seize the opportunity to do a good job in afforestation and strive to improve the survival rate of saplings.

Cold dew: a sign that the temperature drops, the vegetation gradually withers and the weather turns cold. At this time, it is the suitable period for direct seeding rape in the Yangtze River basin and planting winter wheat in Jiangbei area. Agricultural production should be harvested and sown in sunny days; On the other hand, according to local conditions, we should take various effective farming measures such as deep ditch and high compartment to reduce wet damage and improve sowing quality.

First frost: it's freezing. At this time, it is the harvest season of crops in Da Chun. In production, farmers should be instructed to harvest at the right time, and then plough the farmland, sow spring-sown crops, and cover them with plastic film for insulation to ensure the smooth growth of spring-sown crops.

Beginning of winter: Winter starts here. Climatic conditions are suitable for rape transplanting. Wheat with short growth period and strong elasticity should also be sown, because there are many strong cold air attacks in the later period of beginning of winter, and the temperature often drops greatly. If the temperature after sowing is low and the seedling emergence is slow, the yield will be affected. Do a good job in harvesting and drying late rice. Do a good job of sweeping up the winter wheat sowing.

Xiaoxue: The temperature drops rapidly, and it generally begins to snow in the Yellow River basin, entering the snow season. Prevent the damage of frost to crops, and at the same time do a good job of keeping livestock warm and cold.

Heavy snow: the snowfall is increasing, and there is snow on the ground. The low temperature of snow water can freeze the overwintering pests on the surface and bring benefits to agricultural production. However, it is also necessary to strengthen the field management of spring flowers such as winter wheat and rape.

Winter solstice: strong cold air indicates that winter is coming, and cold winter is coming. In agricultural production, strengthen the management of fertilizer and water in spring sowing crops, and focus on antifreeze. It is also the slack season, and we are doing the work of collecting farm manure in our spare time.

Slight cold: the climate is cold and the temperature is low. Accumulate fertilizer to make fertilizer, repair water conservancy, start greening and planting trees, and clean up and transform fish ponds.

Great cold: the coldest time of the year. The activity of agricultural production decreased obviously, mainly to prepare for fallow and planting plan in the coming year.
