Farming began after rain and solar terms. What if there is not enough sunshine? After wheat sowing, it rains on cloudy days, which has little effect, especially in most arid areas of Gansu Province, where there is no watering condition. It is a good thing that cultivators can't wait for the next rain after sowing wheat. When it rains in autumn, it can basically meet the water needed for the growth of wheat seedlings before winter. Moreover, it rains on cloudy days, and after sowing, the loose soil surface can be naturally practical, forming a natural upper solid soil, and the wheat roots are deeply planted. The germination of wheat seeds must meet a certain water content, which is also a necessary condition for the germination of all crop seeds. When sowing wheat, if the soil moisture content is poor, farmers should spray water on the wheat seeds in advance to let the seed coat absorb water and expand slowly, which can speed up the germination and excavation time after sowing. Therefore, it is more important for wheat to emerge quickly, completely and neatly with continuous rain, sufficient water and thorough seed coat after sowing.

It usually takes about 7 days for wheat to germinate after sowing. Although it rains on cloudy days, as long as the temperature does not drop below 12℃ during this period, there is no problem for wheat seeds to germinate and emerge. If it rains on cloudy days, it is sunny and sunny, hard skin may form on the soil surface, which may pinch wheat seedlings and affect growth. When the soil surface is half dry, use a hoe in the morning. In short, after wheat is sown, it is necessary to ensure that the seeds germinate at a certain humidity and temperature before they can germinate and be unearthed. Although it rains on cloudy days, the temperature will not drop too much, which can generally meet the needs of seed germination and growth. It rains on cloudy days, which can not only make the soil fully wet and collect water, but also increase the time of germination and excavation. Not only does it have no influence, it also has more benefits such as accelerating seedling emergence, naturally stabilizing the soil, collecting rain and crouching wet, promoting seedling growth, and being conducive to safe overwintering.
