What does the rainstorm on March 9 portend?

It rained heavily on March 9, and there are two kinds of folk sayings. One means there is no shortage of rain in dog days, and the other means it will be cold in March.

1, "There is a lot of rain and snow in March and September, and there is no shortage of rain in dog days."

The meaning of this proverb is easy to understand. If there is a lot of rain and snow on March 9, there will be relatively more rain in the dog days of the next year, and there will be no drought. From the perspective of agricultural planting, the dog days in 2022 began in July 16, when summer sowing crops were in the stage of emergence and jointing, and the water demand was relatively large.

2. "It is rainy in March and cold in March."

Literally, this proverb says that if it rains during March 9, there may be a chill in late spring in March. In March, the solar term arrived. From the perspective of crop planting, the crops in the field have begun to turn green, and spring ploughing and spring sowing have also entered the preparation stage. If there is late spring cold at this time, on the one hand, winter crops growing in the ground may be frozen. For example, for wheat, the impact of late spring cold is still great, and if it is serious, it may be completely harvested.

Basic knowledge is about three or nine days.

Sanjiu refers to the three cold days from winter to Sunday to everyone's day, which is the coldest time in a year. The algorithm of "three nine days" is to calculate a "nine" every "nine days" according to every day of the winter solstice (official calendar). The first nine days are called "Yijiu", the last nine days are called "Erjiu", and so on. The coldest period of the year is "March 9th". Until the 81st day of "999", the weather will be warm when "nine peach blossoms bloom".

This method of calculating the March 9th cold weather has been circulated among the people in China since ancient times, with a history and lack of records. The method of counting nine has been popular at least in the Northern and Southern Dynasties. Liang Zongzong wrote in the Chronicle of Jingchu: "It is cold to use the number of winter solstice days, 998 1 day." In the traditional culture of China, nine is the extreme number, which is the largest, largest and longest concept. Nine nines is eighty-one, which is the "maximum" number. Ancient people in China believed that from the date of winter solstice to September of August1year, spring would definitely come.
