Spring Equinox: Wednesday, March 21, 2018 00:14:29 On the day of the vernal equinox, the sun shines directly on the equator, and the length of day and night is almost equal. Afterwards, the position of direct sunlight gradually moves northward, and the days begin to get longer and the nights shorter. The Spring Equinox is a relatively important solar term. It not only has astronomical significance: the day and night are equal in the northern and southern hemispheres; it also has obvious climatic characteristics. During the Spring Equinox, my country enters a bright spring except for the Qinghai-Tibet Plateau, Northeast China, Northwest China and the northern part of North China. On the vast land, willows are green, warblers are flying, grass is growing, wheat is jointing, and rape flowers are fragrant.
In early spring , when the temperature rises quickly and then remains low for a period of time, this weather phenomenon is called late spring cold. In the south, the main impact of late spring cold is the rot of early rice seedlings. In northern China, it will affect the growth of peanuts, vegetables, and cotton, and in severe cases it will even cause the death of wheat seedlings. There was once a very severe late spring cold snap in the middle and lower reaches of the Yangtze River in China, which happened to be during the vernal equinox, from late March to early April 1976. The loss of grain seeds in Hunan, Jiangxi and Hubei provinces alone amounted to 700 to 800 million jin.
In northern China, especially in the northwest and north China, there is a saying that "nine out of ten years there are spring droughts" and "spring rain is as precious as oil". In the winter when there is little rain and snow, winter wheat is in the overwintering stage and is not very sensitive to water shortages. After entering March, the soil thaws and wheat turns green; spring crops are sown from south to north. If precipitation continues to be low at this time, drought will be obvious and the situation of the seedlings can be imagined.
