What does the technology of growing wheat mean "light snow never leaves the soil, and heavy snow never leaves the mother"?

Light snow never leaves the soil, that is, it grows wheat in solar terms, and the growth of wheat comes from the soil. Heavy snow never leaves mother, which means that wheat is planted in heavy snow season. The temperature is too low for wheat to germinate at all. So remind friends of wheat farmers not to plant wheat after light snow, and don't think that wheat can be planted as long as the ground is not frozen after light snow.

No one can be sure when the heavy snow will fall. Freezing wheat before winter has become an important work to prevent freezing damage and protect seedlings. Watering the wheat needed in the future once in early winter can prevent the seedlings from freezing injury and death caused by rapid temperature change. Planting wheat after returning straw to the field requires watering, which will also promote straw rot.

The green period of wheat usually occurs in March. During this period, the weather is unstable. What I fear most is "chilly spring". Sudden cold current will cause freezing damage to wheat, especially affecting yield. "It rains in March during the wheat harvest season, and wheat is afraid of cold in March." If the weather is stable in March, there will usually be a good harvest, especially when it rains, and wheat can be replenished in time. However, the weather is warm and cold in March, and the newly grown wheat leaves have poor resistance and are easy to freeze to death, and pests and diseases may break out.

The wheat harvest season is the most terrible season. The right place and the right time are indispensable, especially in the past when wheat was harvested artificially. It is most important to seize the opportunity. During this period, the weather changes dramatically, and strong winds and heavy rains will have a great impact on the wheat harvest. When the wheat fell, it basically stopped filling. According to the rural view, although agriculture depends on the weather to get food, it cannot be separated from the management of science, technology and experience. Many years ago, people passed down these experiences in the form of folk proverbs, which can be said to be our precious wealth.
