The old calendar predicted less rain this year.

Xiaoman is approaching, as the old saying goes, "Look at Xiaoman in a year of drought and flood": Is it drought or flood this year? The old proverb is as follows:

First, Xiaoman was dissatisfied and broke the ridge.

"Full" means full of rain. As the agricultural proverb says, "The rivers are getting full when the solar terms are small", which means that under normal circumstances, in the southern part of China, when the solar terms are small and full, there will be more rain, and the water in the rivers will gradually fill up, which indicates that there will be abundant rain in the future.

An agricultural proverb says, "Dissatisfaction leads to a broken spine." . In other words, if there is no rain or less rain in Xiaoman solar terms, it indicates that there will be less rain in the next period, which is easy to cause the phenomenon of field cracking.

It doesn't rain in Xiaoman solar terms, indicating that the subtropical high is weak and the northern ridge of the subtropical high is south. With the northward movement of the subtropical high ridge, the precipitation line in China will also move northward.

Second, it is too small to hold, and the plow is too high.

This agricultural proverb means that if it doesn't rain on the day of Xiaoman solar term, according to the experience of our ancestors, it indicates that there will be little rain in the next period and drought will easily occur. Seed germination and excavation need rain, farmers can only postpone sowing when the soil is dry, and the plough can only be temporarily idle.

"Peasant Proverbs" also said: "Little people have no rain, and husbands have no rain." This agricultural proverb means that if it doesn't rain on the day of Xiaoman solar term, it means there will be less rain in the dog days.

The dog days are the highest and hottest time of the year. At this time, the growth rate of crops is very fast, and the water demand of crops is large. At this time, if it doesn't rain, it is easy to have a "summer drought" and crops will be reduced because of drought.

Three, a little full of thunder, forty-five days.

The farmer's proverb says, "A villain is full of thunder, but he will fall in forty-five days." If it thunders and rains on Little People's Day, it indicates that there will be plenty of rain for a long time to come. The "forty-five days of rain" here does not mean that it will rain in the next forty-five days, but that there will be more rain in the next period.

Fourth, the wheat is windy and empty.

The "strong wind" here is dry and hot wind, which often brings high temperature and drought, leading to early maturity of wheat at milk maturity, which is very unfavorable for the accumulation of organic matter. Wheat will suffer from grain shortage and 1000-grain weight decline, and the wheat yield will be reduced by 20% ~ 30%.

Farmers depend on the sky for food, and ancient farmers were weak in resisting natural disasters. In modern agricultural production, we can spray 400 times of potassium dihydrogen phosphate foliar fertilizer every 7 ~ 10 days during wheat filling period, which can effectively improve the stress resistance of plants and significantly improve the yield and quality of wheat.
