The leek grows thinner and thinner. How to plant it to make the leek grow stout?

Summary: leek grows thinner, how to plant to make leek grow thick?

If the first stubble leek is very fine, this situation obviously belongs to insufficient nutrition. However, if the second and third crops of leek are relatively fine, this situation is actually difficult to solve even through fertilizer and water. Scientific Xingnong looked at some of the views of other friends on leek not stout, think their views are indeed a bit far-fetched, let's talk about it below.

If the problem of weak growth of leek is summarized, the root cause is insufficient nutrition supply, but if you ask the root, there are many factors leading to insufficient nutrition supply, such as leek diseases and insect pests, too high planting density, shortage of fertilizer and water, etc., no matter what the reason will lead to poor growth of leek.

However, there is also a situation in which leeks are cut more and more finely. For this situation, scientific agriculture thinks it is normal, but it is unreasonable to say that the more they are cut, the thicker they are. After all, the leek had accumulated sufficient nutrients at the initial stage of growth. However, after cutting a few crops, the roots of the leek had basically aged. The ability of the roots to transport nutrients was already a lot worse. It was unrealistic to expect that the leek would still be strong at this time.

Of course, in addition to eliminating diseases and insect pests, strengthening topdressing management can improve the growth potential of leek, but even so, it is difficult to catch up with the first crop of leek. The best way is to implement the strategy of recuperation, so that leeks can have enough growth space to reproduce.

After the first crop of leek is cut, the root of leek will redevelop and produce many new leeks. At this time, the density of leek in the field will increase greatly. The photosynthetic utilization rate of single leek is insufficient, and the space density is too large to cause leek to grow well. Therefore, a better solution is to pick seedlings in the field and reduce the density of leek in the field.

When entering the second or third crop, topdressing is needed at this time. It is usually thought that leek lacks nitrogen fertilizer, so nitrogen fertilizer supplement is enough, but this practice is obviously not enough. Nitrogen fertilizer can promote nutrition extension and promote green color of leek leaves, but phosphorus and potassium fertilizer are also indispensable. Supplementing phosphorus and potassium fertilizer helps strengthen plant roots and stems and improve plant disease resistance. For leek fertilization can be used to spray leaves can be faster effect. However, this could only be said to improve the growth of leeks. It was still difficult to expect them to grow like the first leek.
