Winter irrigation is to irrigate the fields during the winter, so that the soil can increase the water storage capacity and prevent the spring drought in the coming year. This method is commonly used for winter wheat planting in northern China to achieve the purpose of increasing production.
Wintering water can prevent winter wheat from freezing and killing dead seedlings, and save water for the next year. It can be used for spring water, spring drought and early prevention. At the same time, it can reduce the number of bacteria and eggs, lower the number of pests and diseases, and reduce the pests and diseases of Mingchun. It is an important measure to ensure the safe wintering of wheat. The combination of the new high-fat film and Zhuangsuiling can protect the humidity and temperature of the seedlings, prevent disease and deworm, and inhibit the replication of pathogens. It can increase the water absorption and fertilizer absorption of wheat and increase the yield and quality of wheat.
The amount of winter wheat irrigation should not be too large, generally 50-60 cubic meters per 667 square meters. In order to save water, it is necessary to make a channel to prevent flooding. After the winter irrigation of wheat, it is necessary to draw the loose soil in time to bridge the cracks, to break the knot, to ensure the temperature increase, to prevent the wind and the roots from causing the dead seedlings, and to ensure that the wheat can safely pass through the winter.
