What are the latest remedies for missing wheat seedlings and broken rows?
Wheat is one of the main food crops in our country, and it has a very large planting area in our country. Although wheat cultivation methods are relatively simple, some problems often occur during cultivation, and missing seedlings and broken rows is one of them. If wheat has missing seedlings and broken rows, it will have a very large impact on its yield. So how should missing wheat seedlings and broken rows be remedied? Below, the editor will briefly introduce it to everyone. Let's take a look together!
1. Causes of missing seedlings and broken rows
When wheat is planted, uneven emergence often occurs for many reasons. Generally, if no seedlings have grown within about 10cm in the wheat rows in a wheat field, then it is basically considered missing seedlings. If there are no wheat seedlings for more than 15 centimeters, it is regarded as a broken row. There are very many causes of missing wheat seedlings and broken rows, for example, extensive management during tillage, resulting in many clods. Or sowing when the soil moisture is yellow moisture, resulting in insufficient subsoil moisture.
When sowing, pay attention to the sowing depth of each sowing hole; some must not be sown deep and some shallow. If the sowing depth is inconsistent or if sowing is missed or skipped, then missing seedlings are also very likely to occur. In addition, seed quality is also a key factor affecting wheat emergence. After sowing, if it is harmed by underground pests, or if the seeds and soil are improperly disinfected, it is easy to cause phytotoxicity, thereby affecting wheat seed emergence. Wheat fields with missing seedlings and broken rows should be dealt with promptly; otherwise, it will not only reduce the utilization rate of land resources, but also reduce yield.

1. Check seedlings and replant
About 4 days after wheat seeds are sown and emerge, we should do a good job of checking seedlings and inspect whether there are missing seedlings. If there are missing seedlings, then replant promptly. When replanting, first we should use seeds of the same variety and soak them in warm water at about 20 degrees for about 4 hours. Then remove them, let the seeds fully absorb water, and keep them in a moist state. When the seeds show signs of sprouting, furrows can be opened for replanting. If the moisture is poor, then water appropriately along the furrow, and after sowing cover with soil and press it firm.
2. Thin seedlings and transplant
After the small seedlings enter the tillering stage, if there are still missing seedlings. Then we should promptly thin seedlings and fill in sparse areas, transplanting while filling in. When transplanting, keep the robustly growing seedlings and remove weak seedlings. When transplanting and covering with soil, pay attention to controlling the depth. Do not press on the heart of the seedling, and do not expose the seedling roots outside. Do a good job of management after planting; if the moisture is poor, water promptly. Some quick-acting fertilizer can be applied appropriately to improve the survival rate and growth speed of the seedlings.
