After the vernal equinox, the overwintering crops in most parts of southern China entered the spring growth stage. In central China, there is an agricultural proverb that wheat rises at the vernal equinox and is worth a thousand dollars in an instant. The temperature in most parts of the south continues to rise, but generally it doesn't rain as fast as the vernal equinox. In late March, the average temperature in northern South China is mostly 13℃ to 15℃, and in southern South China it is mostly 15℃ to 16℃. Most of the plateau has been melted by snow, and the ten-day average temperature is about 5℃ to 10℃. 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.
