What month is the cold spring?

"Cold in late spring" describes the season of early spring, which means to describe the cold in early spring. Early spring, also known as Meng Chun, is the first month of spring, which usually refers to the first month of the lunar calendar, specifically the period from beginning of spring to jingle. Early spring is divided from astronomy.

Spring, also known as spring, is the first of the four seasons, which refers to the period from beginning of spring to long summer, including solar terms such as beginning of spring, rain, fright, vernal equinox, Qingming and Grain Rain.

The harm of late spring cold:

"Cold Spring" is a frequent visitor in spring, and its influence covers the north and south of China. From February to April throughout the year, South China and South China have successively entered the busy season of early rice sowing and seedling raising. During this period, cold air and warm air had a positive confrontation. When the northern cold air invades Jiangnan and South China, the cold and warm air are evenly matched, which often leads to low temperature and rainy weather.

When the daily average temperature is ≤ 12℃ and lasts for 3 to 5 days or more, or the temperature drops sharply in a short time, and the daily minimum temperature drops below 5℃, it may cause early rice seedlings to rot and die. The "late spring cold" in the north mainly affects winter wheat and fruit trees.

When the temperature is high in the first spring, winter wheat enters jointing stage, booting stage and even flowering stage, and fruit trees enter flowering or young fruit stage, so the cold resistance drops sharply. In the second spring, cold air strikes and the temperature drops obviously, causing "late spring cold" and even frost damage, which will have a great impact on the production of winter wheat and forest fruits (such as peaches, apricots, walnuts, grapes, etc.). ), in severe cases, it will lead to a significant reduction in forest fruit production or even no harvest.
