What is suitable for planting around the vernal equinox

What crops are suitable for planting at the vernal equinox? What crops are suitable for planting around the vernal equinox?

Spring is suitable for planting rice, corn, soybeans, peanuts, cotton, wheat, sweet potatoes, sesame and other crops. Rice should be sown before Qingming in North China, around April in Northeast China and mid-April in the middle and lower reaches of the Yangtze River. Corn is sown in late March and April in the south, late April and early May in North China, and late April to early May in Northeast China. In northern China, soybeans are usually sown in April-May. Peanuts are usually planted from the end of April to the beginning of May; Sweet potatoes are usually sown from mid-February to mid-April.

What farming activities are there in the spring equinox solar terms?

When the vernal equinox comes, many agricultural preparations will be made in advance, such as purchasing seeds, fertilizers, pesticides, farm tools, etc. needed for spring ploughing, so as to sow in time after the weather clears up. After that, farmers will choose seedling fields, arrange seedling boxes, and then do a good job of seed treatment to increase germination rate and improve germination potential. During this period, seeds and bed soil will be strictly disinfected and soaked intermittently. In recent years, seedling raising technology is also very advanced, as long as there is enough rain, it will not be a problem. According to the weather conditions, people will also pay close attention to the sowing of double-season early rice, quantitative, sparse and even sowing, and cultivate strong seedlings. At this time, we should pay more attention to weather forecast in order to strengthen field management.

Matters needing attention in sowing at vernal equinox

1. There are different forms of water management in the north and south in spring. For example, there is little rain in the north, so we should pay attention to watering. The rainfall in the south is relatively large, so it is necessary to pay attention to the timely discharge of excess water in the field. No matter what crops are planted, water is very important for their growth. We also need to pay attention to the weather when sowing, not in rainy days, to avoid too much water, hinder seed germination and reduce seed germination rate. It is best to keep sunny for 3-4 days after sowing to improve the overall seedling rate of seeds.

2. Fertilization management For some crops that can blossom and bear fruit every year, spring is the season of budding and new shoot growth. At this time, the demand for nutrition of crops is relatively large, so for some crops with new buds, nitrogen fertilizer should be applied in time to meet the nutrition needed for growth. When sowing in spring, base fertilizer should be applied, and the base fertilizer is mainly decomposed farmyard manure. The nutrition of farmyard manure is very comprehensive, which can completely meet the needs of early crop growth. Then, appropriate fertilization should be applied according to the growth of crops in spring to ensure the healthy growth of crops.

3. Temperature management Different crops have different requirements for temperature. The temperature of solar terms in the vernal equinox gradually rises to about 15 degrees, and the temperature is warmer in most areas. It is very suitable for planting corn, rice and other food crops. It is also necessary to adjust the temperature reasonably according to different crops to avoid the influence of temperature on the growth of planted crops. Moreover, the temperature changes greatly in spring, and the temperature difference between day and night is relatively large. We should also pay attention to observing the weather changes, so as to adjust the temperature in time and create a good growth environment for crops.

4. Pest control Spring is the season when everything recovers. Of course, germs and pests are no exception. The environment with high temperature and humidity in spring is most likely to cause various diseases and insect pests and affect the growth of crops. Therefore, we need to do a good job in the prevention and control of pests and diseases when planting at the vernal equinox. Rational fertilization, strengthen water management, control the dosage when meeting the demand of water and fertilizer, and avoid fertilizer damage and waterlogging damage affecting crop growth. Finally, the control of temperature and planting environment. It is necessary to cut off the transmission route of germs, enhance the disease resistance of crops, reduce the incidence rate and protect their own planting benefits.

Twenty-four solar terms farming arrangement

Beginning of spring: Rapeseed topdressing, drainage, intertillage weeding, welcome to apply a large amount of moss fertilizer.

Rain: Barley grains enter jointing and booting stage one after another.

Surprise: Early rice seedling raising and afforestation.

Equinox: We will continue to control wheat and rape, plant trees, improve and protect the ecological environment, and adjust the climate.

Qingming: When rice is sown in wheat festival and rape blossoms, field management cannot be relaxed. Corn and peanut seeds.

Grain Rain: The whole country is ready to cut wheat, raise seedlings and sow cotton.

Long summer: Spring flower crops should be harvested in time when they enter the yellow maturity stage. After the long summer, Zhejiang will enter the rainy season. The rainy season is about to begin.

Xiaoman: The northern region needs to strengthen the late management of wheat fields. Spring corn, sorghum, intertillage, weeding and ridging are particularly important.

Ear seed: early rice cultivation management, timely cutting sun-dried fields, raising soil temperature, and paying attention to pest control. Sow late rice at the right time.

Summer solstice: clear weeds in time and control pests and diseases.

Summer heat: strengthen water storage and drought prevention, and strive to achieve flood control and drought relief.

Summer: We must strengthen the management of water and fertilizer in the field. Late rice should be transplanted before beginning of autumn.

Beginning of autumn: Late rice should be cultivated and weeded, and irrigated in case of drought. Grasp the 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 picking. Winter wheat and rape should be prepared before sowing.

Cold dew: large daily temperature difference is beneficial to late rice fruiting. 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: We should strengthen the cultivation and management of rape and garden vegetables. The accumulation of forest fire prevention funds 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 in 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.

Slight cold: In addition to its own periodic changes, the depth, breadth and intensity of human activities, abnormal atmospheric circulation, smoke and dust from volcanic eruption and many other factors have affected the internal periodic changes of climate.

Great cold: main farming activities: storing and making fertilizer, repairing water conservancy in winter, starting greening and planting trees, cleaning and transforming fish ponds.
