The proverb "cover the wheat with the third layer this winter and sleep with steamed bread next year" means that the heavier the snow in winter, the thicker it will be spread on the crops like a quilt, and the better the wheat harvest next year. This is because in the north, a thick layer of loose snow is like covering wheat with a quilt to keep out the cold. The cold nitrogen in snow is easily absorbed and utilized by crops. The low temperature of snow water can freeze the overwintering pests on the surface, and it will also bring benefits to agricultural production and bring more harvests in the coming year? .

This is an agricultural proverb about crops, and similar sentences include:

1, no sowing in spring, no harvest in autumn.

2, jujube buds, cotton planting. ?
