Wheat didn't sprout in winter, even in rainy days. Will it affect the emergence rate?

After wheat sowing, in case of continuous rainy days, if the rain is heavy, there will be water in the field for a long time, or the soil will be sticky. After the rainy days, the soil permeability will be poor, and the surface soil will harden and agglomerate, so that the wheat seedlings cannot break through the soil layer. If the weather improves after a heavy rain after sowing, you should worry about the poor emergence rate. However, if it is in a continuous rainy day after sowing, as long as the temperature is not very low, it is conducive to seedling emergence, so it is unnecessary.

Generally speaking, if we must choose to plant wheat before or after it rains, we usually plant it before it rains, because wheat is usually planted on sticky land. After the heavy rain, we can't sow immediately because it is difficult to sow. At this time, we must strengthen field drainage to prevent water accumulation. After the weather is fine, the hardened surface should be broken to accelerate the evaporation of water and improve the germination rate of wheat.

After continuous rainy weather, loosen the soil to avoid soil hardening, resulting in poor seedling emergence, which is helpful for wheat seedling emergence. At present, the rainfall in autumn is usually relatively small, and it will not be a rainstorm. On the contrary, it will rain continuously. This silent Mao Mao rain has no adverse effects except slowly wetting the soil to promote seedling emergence. When planting wheat, it is necessary to level the field and make a good drainage ditch to ensure timely drainage during waterlogging and convenient watering during drought. Only in this way can we ensure the high yield of wheat.

It usually takes about 6-7 days from sowing to emergence of wheat. If it rains after sowing, the ground will be dry by the time the wheat emerges, so it should be treated in time. When wheat was unearthed, the ability of covering soil was relatively poor. When the tide ebbs in the morning, the scabs on the surface are scraped off gently with a vegetable rake, which provides good conditions for unearthed wheat seedlings. Our ancestors called it "scarred wheat seedlings". Some seeds are sown deep and shallow, some are completely exposed, some are sown too shallow, and will soon dry up after the sun is exposed. It is difficult to sow all the seedlings at once without rain at this time.
