What is Xiaoman? Will it rain?

Every year from May 20th to 22nd, when the sun reaches 60 degrees, it is in full bloom. "Twenty-four solar terms" said: "In mid-April, small people are full, and small things are full." At this time, the seeds of summer sowing crops such as wheat in the northern region have begun to be full, and the wheat grains seem to be full. In fact, they are only "half full" and have not yet matured, so they are called "little full". Summer harvest, summer sowing and Shimonoseki are the prelude to three busy summers, and it is also a busy season for farmers in a year.

According to meteorologists, from the perspective of climate characteristics, during the period from Xiaoman solar term to Mang solar term, all parts of the country entered summer one after another, the temperature difference between north and south further narrowed, and precipitation further increased. Meteorological data show that after Xiaoman, high temperature weather above 35℃ began to appear in some areas of China.

Xiaoman solar terms should pay close attention to the prevention and control of pests and diseases in wheat fields, and prevent dry hot winds and sudden thunderstorms and hail attacks. South China should pay close attention to rice topdressing and weeding, and summer crops should be harvested and dried in sunny days. During this period, we must pay attention to watering "wheat yellow water", pay close attention to preventing and controlling pests in wheat fields, and enhance the growth of wheat. At the same time, some effective windproof measures should be taken to prevent dry hot wind and sudden thunderstorm and gale.
