According to the twenty-four solar term song, talk about the relationship between the twenty-four solar terms and agricultural production!

beginning of spring: Literally, it is the beginning of spring. The plan of the year lies in spring, which is the busy time of farm work in a year. All plants revive and sprout, and farmers remove weeds, collect fertilizers, clear ditches and drain water to prevent waterlogging, and promote crop growth.

rain: the weather is getting warmer, the snow and ice are melting, the air is moist, and it begins to rain and the rainfall increases. Commonly known as: rain and spring rain are as expensive as oil. At this time, crops grow rapidly under the rain, and at the same time, Da Chun production work plan is formulated.

Startling: Spring thunder begins to sound, the weather is clear and the climate is warm, which awakens the hibernating animals in the underground and the trees begin to take root and sprout. At this time, it is the best time for fruit grafting, and early rice is ready to raise seedlings and plant trees.

vernal equinox: spring with warm climate has arrived, and the time of day and night is equal. Farmers do a good job in the field fertilizer and water management in the middle and late stages of spring crops, plow the fields in winter fallow, prepare agricultural production materials such as seeds, fertilizers and agricultural films, and plant trees to improve and protect the ecological environment and adjust the climate.

Qingming: The weather is fresh and warm, and the plants are sprouting new branches. It is the best time to step into spring, and the spring outing in the suburbs is to sweep the graves. The whole country has entered the busy farming season, with early and middle rice sown successively, wheat jointing and rape blooming, and field management cannot be relaxed.

Grain Rain: The heavy rainfall and long time promote the rapid growth of cereal crops. Farmers enter rice seedling raising, sow corn early and prepare for ploughing in spring. Nong Yan has the saying that "the drought will not last until May 13th". If there is no rain or little rain in Grain Rain, it is a sign of drought, so make preparations in advance.

long summer: With the beginning of summer, the new summer is approaching, and everything is thriving. Because China has a vast land area and different geographical and climatic factors, long summer mainly refers to the area south of the Yellow River. Spring flower crops enter the yellow ripening stage, and harvest them in time. Jiangsu and Zhejiang will enter the rainy season, and the rainy season will begin, so we should make good preparations for flood control. Even in rainy weather, we must guard against sprouting and mildew of Koharu harvest, and do a good job in drought resistance and seedling protection.

xiaoman: the grains of wheat crops are full and immature. Farmers harvest crops in Koharu, sow large areas of spring crops such as soybeans and corn, and plant rice, and begin to enter the busy farming season.

awn seed: the season when summer-ripe and summer-sown crops are busy harvesting and planting. The awned crops such as wheat and barley are ripe, and the intense summer harvest begins. At the same time, it is a busy season in summer sowing, so the awn seed is also called "busy planting". In the season of awning, the 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 stage will be vulnerable to drought and pests and diseases, and the yield will not be high. This is the truth of the agricultural proverb "busy planting".

summer solstice: when the hot summer comes, the day is the longest and the night is the shortest in China. There will be drought in some areas. In order to enhance the drought resistance and win a bumper harvest in agriculture, it is an important measure to grab and store the pre-storage 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 control 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. Faced with the turning point of plum flood and drought, while doing a good job in flood control, farmers have strengthened water storage and drought prevention, striving to achieve both flood control and drought prevention.

great summer heat: the hottest period in the whole year, with scorching heat in most areas. Farmers should do a good job in intertillage weeding, field fertilizer and water management, and prevention and control of pests and diseases in Da Chun. Thermophilic crops, the growth rate reached its peak. Field management of water and fertilizer must be strengthened. Transplanting late rice should be done before beginning of autumn.

beginning of autumn: The cool autumn begins, the hot summer gradually recedes, and the temperature begins to drop. Late rice needs intertillage weeding and irrigation in case of drought. Pay close attention to autumn sowing. Cotton topping promotes the development of autumn cotton.

summer: the hot summer is over. Late rice is in a critical period of growth. In order to ensure the water supply for farmland in winter and spring, we should do a good job of water storage during this period. The basin is a busy season for harvesting mid-season rice.

Millennium: the temperature dropped obviously, the weather turned cold, the drizzle began, and the sunshine time became shorter. Actively take corresponding agricultural technology measures to reduce or avoid the harm of autumn rain. In addition, we should seize the rain 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 well.

autumnal equinox: it marks the beginning of a crisp autumn, commonly known as "an autumn rain and a cold rain", 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 collection. Winter wheat and rape should be prepared before sowing. At the same time, we should pay attention to clear the sun, manage soil moisture and prevent waterlogging, and do a good job in the quality and progress of Sanqiu production. Make full use of the meteorological conditions with little rain and good soil moisture in autumn, seize the opportunity to do afforestation and strive to improve the survival rate of saplings.

cold dew: a sign that the temperature drops, the vegetation withers gradually, 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 furrows and high compartments, to reduce wet damage and improve sowing quality.

first frost: It's cold and frosty. 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 plow the farmland, sow the spring crops, and use plastic film to cover the temperature to ensure the smooth growth of the spring crops.

beginning of winter: Winter begins here. Climatic conditions are suitable for rape transplanting. Wheat with short growth period and strong springiness 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 is low after sowing, the seedlings will emerge slowly and 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.

light snow: the temperature drops rapidly, and it generally begins to snow in the Yellow River basin, entering the snow season. Prevent frost from harming 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 ground 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: the strong cold air indicates that the cold winter is coming and the cold winter is coming. In agricultural production, strengthen the management of intertillage fertilizer and water for spring crops, and focus on antifreeze. It is also the slack season, and we do the work of collecting farm manure in leisure.

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

severe cold: the coldest time of the year. The activity of agricultural production activities has obviously declined, mainly to prepare for rest and planting plan in the coming year.
