What farming can we do at the vernal equinox?

Irrigation in spring, drilling wells to save water, applying jointing fertilizer well, and paying attention to preventing late frost and freezing injury; South China still needs to continue to do a good job in drainage and flood prevention. Early rice seedling raising in Jiangnan and Jianghuai areas has started, and the weather changes frequently in early spring. Attention should be paid to soaking seeds to accelerate germination when cold air comes, and sowing in sunny days when cold air ends.

Most areas in South China, such as river valleys, have the highest temperature, with an average of 18℃ to 20℃. In the south, except for the marginal mountainous areas, the average daily temperature rose steadily to above 12℃ in 1978, which is beneficial to planting crops such as rice and corn, and is also very suitable for afforestation.

However, before and after the vernal equinox, there is often a strong cold air intrusion in South China, and the temperature drops obviously, as low as 5℃. Sometimes a small stream of cold air comes one after another, forming a low temperature and rainy weather that lasts for several days, which is not good for agricultural production. According to this feature, we should make full use of the weather forecast, grasp the cold tail and warm head, and sow in time.

Farming refers to agricultural production activities such as ploughing, fertilization, sowing, field management (weeding, lodging prevention, spraying pesticides, insect prevention, cold prevention, freezing prevention, drought prevention, watering, waterlogging prevention, irrigation and drainage), harvesting, harvesting, storage, and six livestock management (feeding and disease prevention).

Agricultural activities cover fruits and vegetables, flowers and trees, Chinese herbal medicines, edible fungi, grain and oil, aquatic products, livestock, pesticides, fertilizers, seeds, agricultural machinery and facilities.
