Remedy for lack of seedling and ridge in wheat field

Wheat production is often uneven due to various reasons. In production, no seedlings with a length of 10 cm in the wheat row are lacking, and no seedlings with a length of 16 cm are broken ridges. There are many reasons for lack of seedlings and ridges, such as extensive farming and excessive hoeing; Scutellaria baicalensis seedlings are inadequate; sown seedlings vary in depth and there are missed sowing; poor seed quality; low seedling rate; underground pest damage; seed or soil treatment Inappropriate phytotoxicity; excessive soil salinity; etc. If measures are not taken on wheat fields lacking seedlings and ridges in time, not only will land be wasted, but yields will also be greatly affected. The remedies generally taken are:

Check seedlings for replanting: 3 to 5 days after emergence, soak the seeds of the same variety with warm water at 20 ° C for 3 to 5 hours, and keep them moist after removing them. When the seeds start to germinate, use a hoe or a trencher to open the trenches for replanting. , When the difference is poor, a small amount of watering along the trench, after planting, cover the soil.

Transplanting sparse seedlings: For areas where there is still a lack of seedlings during the tillering stage, thinning seedlings can be replenished on the spot, and they can be transplanted while being weak to stay strong. The depth of soil covering during transplanting is based on the principle of "no pressure on the top and no whiteness on the bottom". After planting, it should be solid at any time, and watered in time when it is lacking. Conditionally, a small amount of quick-acting fertilizer should be applied to facilitate survival and rapid growth.
