How to remedy the lack of seedlings and broken ridges in the latest wheat

Wheat is one of the main food crops in China, and it has a very large planting area in China. Although wheat planting method is relatively simple, but there are often some problems in planting, and lack of seedlings is one of them. If wheat seedlings are short and ridged, their yield will be greatly affected. So how to remedy the wheat seedling shortage? The following small series will give you a brief introduction. Let's take a look together!

1. Reasons for lack of seedlings and ridge breaking

When wheat is planted, it often emerges irregularly for many reasons. Under normal circumstances, if the wheat field does not grow seedlings within 10cm of the wheat row, then it is basically a lack of seedlings. More than 15 cm without wheat seedlings is regarded as broken ridge. There are many reasons for the lack of wheat seedlings and broken ridges, such as extensive management during farming, resulting in more rice. Or sowing when the soil moisture is yellow, resulting in insufficient soil moisture.

When sowing, pay attention to the sowing depth of each sowing hole, not some deep sowing, some shallow sowing. If the sowing depth is inconsistent or the sowing is missed, it is easy to appear the phenomenon of lack of seedlings. In addition, seed quality is also a key factor affecting wheat emergence. After sowing, if it is damaged by underground pests, or if the seeds and soil are not disinfected properly, it is easy to cause phytotoxicity, thus affecting the emergence of wheat seeds. However, the wheat fields with seedling shortage and ridge breaking should be treated in time, which will not only reduce the utilization rate of land resources, but also reduce the yield.

II. REMEDIES

1, check seedlings replanting

About 4 days after the wheat seeds are sown, we should check the seedlings to check whether there is a lack of seedlings. If there is a lack of seedlings, we should replant them in time. In replanting, we first need to use the seeds of the same variety and soak them in warm water of about 20 degrees for about 4 hours. Then remove it and let the seed absorb water enough to keep it in a moist state. When the seeds show signs of germination, they can be trenched and replanted. If the moisture content is poor, then water it along the ditch and cover it with soil after sowing.

2. Thinning seedlings and transplanting

If there is still a lack of seedlings after the seedlings enter the tillering stage. Then we have to timely thinning seedlings thin, while transplanting, while replanting. When transplanting, keep healthy seedlings and remove weak seedlings. When transplanting soil, pay attention to control the depth. Do not press down to the heart of the seedling, nor expose the roots of the seedling to the outside. Do a good job of management after planting, and water in time if the moisture content is not good. Some quick-acting fertilizers can be applied appropriately to improve the survival rate and growth rate of seedlings.
