Three autumn equinox

The farmer's proverb said: "One autumn rain and a cold", "Bai Lu Qiu Qiu is in the night, cold one night and one night." In the autumn equinox, the Chinese Yangtze River Basin and its vast areas north have entered the autumn divided by "waiting average temperature". The northern air -conditioning group began to have certain forces, cool winds, clear air, clear air, wind and sunny, high autumn and refreshing, and the temperature decreased significantly.

The characteristics of fast cooling in autumn make the "three autumn festivals" of autumn harvest, autumn plowing, and autumn species are very nervous. Cotton spit in autumn is a great time to gain. Winter wheat has begun to sow in North China. The Yangtze River Basin and the vast areas of the south are busy harvesting of late rice.

In particular, even the rain will cause the upcoming crops to fall, mildew or germinate, causing serious losses. "Three autumn" is busy, expensive in the word "early". Getting the autumn harvest crops in a timely manner can avoid the harm of early frost and even rainy rain. Broadcasting in the winter in a timely manner can strive to make full use of the calorie resources before the winter to cultivate the safe and overwintering of strong seedlings, laying the foundation for high yields in the coming year.
