What day is the first day of September?

On the first day of the ninth lunar month, it is the autumn harvest season. Farmers clean up their yards and repair granaries and grain depots. Arrange and store grain, and exchange old and new grain.

China has a vast territory, and the climate between north and south is very different, so the harvest time of main crops is different. Roughly in the Yangtze River valley, around the autumnal equinox, it is time to harvest rice and plow wheat. In the lower reaches of the Yellow River, corn and sorghum have been harvested at this time. In the upper reaches of the Yellow River, crops have also reached the threshing floor.

The poem "The Book of Songs Wandering in July" wrote: "Build a garden in September and harvest crops in October. Millet, millet, rice, millet, millet, millet, wheat. " The poem "July" was originally a popular ballad in the early years of the Zhou Dynasty, which was convenient for farmers to recall their farming activities in the past year. Therefore, according to the purpose of autumn harvest and winter storage, September can be roughly regarded as the time when farmers start harvesting and storing crops such as rice grains.

Step 2 store new grain

Saving grain for a rainy day is enough to adjust the prosperity and regret of a year, so the ancients had the practice of "three years of ploughing, there must be more than one year". China's famine relief system (the relief measures taken in times of famine in ancient times) appeared in the Zhou Dynasty. The "constant square meter" method of building and storing grain began in the Warring States period, when the grain was cheap, and when it was expensive, it was sold at a reduced price to adjust the price of rice.

Rumor: On a rainy day in September, crops will be reduced in late autumn.

If it rains on the first day of September, it indicates that crops will be reduced in late autumn.

As the saying goes, "an autumn rain brings a cold." Whenever it rains in autumn, the weather becomes cool. If there is rainy weather on the first day of September, it indicates that the temperature will drop faster and the weather will get colder and colder. It is very unfavorable for late autumn crops that are still in the growing period. The emergence of low temperature will slow down or stop the growth of crops, especially late rice, which will lead to the early termination of the growth period of late rice, the increase of empty grains in rice, and the reduction of production or poor harvest.
