Rain: At that time, the wheat gradually entered the jointing and booting stage, and the seedlings were fertilized, and the ditch was cleaned and drained to strengthen the field management of rape. Stunned: The management of fertilizer and water should be strengthened in the wheat field, and the soil moisture should be divided into three types: Wang Shui, Black Moisture, Yellow Moisture, Wet Dry Soil and Dry Soil, seedling, irrigation and water saving. Application of coating fertilizer to rape. Early rice is ready to raise seedlings and plant trees.
Vernal equinox: From south to north on both sides of the Yangtze River, early rice has been soaked to accelerate germination, and plastic film has been used to raise seedlings (to prevent cold wave), and the cold tail and warm head are used to grab the eye for sowing. We will continue to manage wheat and rape and do a good job in afforestation, improve and protect the ecological environment and adjust the climate.
Qingming: The north and south of the Yangtze River have entered the busy farming season. Early and middle rice are sown successively, wheat is jointing, rape is blooming, and field management cannot be relaxed. Sowing corn and peanuts. Grain Rain: At this time, it is the busy season for rural areas to prepare for wheat cutting, rice transplanting and cotton planting.
Long summer: When the spring flower crops enter the yellow ripening stage, they should be harvested in time. After long summer, Zhejiang will enter the rainy season, and the rainy season will begin, so it is necessary to prepare for flood control. Xiaoman: The summer crops in the north and south of the Yangtze River have matured one after another, and they are harvested in a sunny way. The late management of wheat field should be strengthened in northern China. Spring corn, sorghum, intertillage, weeding and ridging are particularly important. Ear seed: We should pay close attention to the cultivation and management of early rice, timely cultivate and bake fields to improve soil temperature, and pay attention to the prevention and control of pests and diseases. Sow late rice at the right time.
Summer solstice: We should seize the opportunity to strengthen field management in summer, clear weeds in time, and control pests and diseases. Summer heat: Summer heat is facing the turning point of plum flood and drought. While doing a good job in flood control, all localities should grasp the weather forecast information in time, strengthen water storage and drought prevention, and strive to achieve both flood control and drought prevention.
Great summer heat: a warm-loving crop, its growth speed has 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: For late rice, intertillage should be used for weeding, and irrigation should be used in case of drought. Pay close attention to autumn sowing. Cotton topping promotes the development of autumn peach (cotton). Summer: At this time, late rice is in a critical period of growth.
Bailu: cotton is picked in batches, and the field management of autumn corn and other crops is strengthened in the later stage. Autumnal Equinox: 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. Cold dew: The cold dew solar term is the suitable period for direct seeding rape in the Yangtze River basin, and winter wheat is planted in Jiangbei area.
First frost: It is necessary to strengthen the cultivation and management of rape and garden vegetables. The accumulation of funds for forest fire prevention should also be implemented as soon as possible. Beginning of winter: Do a good job in harvesting and drying late rice. Do a good job of sweeping up the winter wheat sowing.
Xiaoxue: Do a good job of keeping livestock warm and wintering.
Heavy snow: It is necessary to strengthen the field management of spring flowers such as winter wheat and rape.
Winter Solstice: Strengthen the field management of spring flowers such as winter wheat and rape. Great cold: main farming activities: accumulating fertilizer, making fertilizer, repairing water conservancy in winter, starting greening and planting trees, and cleaning and transforming fish ponds.
Twenty-four solar terms originated in the Yellow River Basin. As far back as the Spring and Autumn Period, four solar terms, namely, mid-spring, mid-summer, mid-autumn and mid-winter, were set. After continuous improvement and perfection, by the Qin and Han Dynasties, the 24 solar terms had been completely established. Including beginning of spring, Rain, Sting, Vernal Equinox, Qingming, Grain Rain, long summer, Xiaoman, Mangzhong, Summer Solstice, Slight Summer Heat, Great Summer Heat, beginning of autumn, Summer White Dew, Autumn Equinox, Cold Dew, first frost, beginning of winter, Light Snow, Heavy Snow, Winter Solstice, Slight Cold and Severe Cold.
The 24 solar terms are divided according to the position of the sun on the ecliptic. Depending on the sun starting from vernal equinox, every advance of 15 degrees is a solar term; After a week's operation, I returned to vernal equinox, which is a tropical year, which is 360 degrees, so it is divided into 24 solar terms.
