The timely replanting of wheat fields that are severely short of seedlings and ridges must be replanted with seeds of the same variety at the seedling stage.
Tightening and thinning the whole field is better, only a few places lack of seedlings, seedlings of wheat, can be transplanted in the three-leaf stage of wheat thinning with soil transplant. When transplanting, do not press on the heart, do not reveal under the white, buried water after covering, and make up the appropriate fertilizer, in order to facilitate the slow seedlings.
Drought and replenishing water should be promptly watered for the wheat fields that are short of seedlings due to drought. Once a day, they should be poured for 3 to 5 days to promote the normal growth of the wheat seedlings and increase the number of seedlings.
The late-seeding wheat fields that are planted with warming and cultivating seedlings, such as the fact that wheat has not emerged after sowing, will experience cooling weather, coupled with high soil moisture, low ground temperature, and insufficient accumulated temperature, will result in prolonged seedling emergence and incomplete emergence. Slug warming to promote early emergence.
Fertilization and growth promotion are more uniform for wheat seedlings, but the basic wheat seedlings are insufficient. You can grab fertilization from the seedlings to the 3-leaf stage, use mainly available nitrogen fertilizers, apply early-appropriate seedling fertilizers, promote early tillering and sub-seedling, and optimize individuals. The purpose of early winter strong hair.
To remove the soil from the cover of the wheat field that caused the seedlings to grow too deep, you can remove part of the soil cover, combined with irrigation and cultivator, improve the ventilation of the soil and promote lateral root development.
Prevention and treatment of pests and diseases before winter wheat is mainly root diseases and underground pests, to take poisonous soil, irrigation and other control measures in time to eliminate pests and diseases, so that weak seedlings as soon as possible.
To prevent salt damage caused by salt damage wheat fields, should be timely cultivating loose soil, using irrigation salt or salt drainage method to reduce soil salinity.
