Good method of transplanting cotton seedlings

When the cotton is in seedling stage, due to various reasons, the phenomenon of lack of seedlings and ridges often occurs, which requires transplanting seedlings. The traditional method of transplanting seedlings is to use a transplanter to make a hole in the hole, use the transplanter to take the seedlings from the seedlings, insert the holes, and pour the water. The survival rate of such a seedling method is low, and the seedlings that are transplanted are always long. What is the problem? Is it watering? According to tradition, the seedling roots are injured when the seedlings are transplanted, and the water absorption capacity of the seedling roots is affected. Therefore, sufficient water must be poured. However, the actual situation is not the case. When the mowing device is used to take the seedlings, the soil in the mowing device is compacted. Although the root is injured, it is not fatal. The problem of not watering is not large, and the water is poured. The problem came, and the inherent stress of the compacted soil under the action of water (produced when the seedlings were taken) was fully released. This release completely broke the capillary roots of the original injured seedlings, and the capillary roots of the seedlings were broken. It is the mouth of the seedling who drinks water. What is the use of the mouth without water? The dry transplant seedlings are transplanted without watering at the time and watered on the next day. When the internal stress of the seedling blanks is released gradually over time, the water stress is gradually released and the survival rate of the cotton seedlings is lower than the original. 20% increase to 90%, and the growth in the later period is also very good. Of course, we must pay attention to some operation methods without watering and transplanting seedlings. Do not move the seedlings in the middle of the day. It is best to use rainy cloudy days after 2:00 in the afternoon. The roots of the seedlings should be earth-rooted, if a few hay are used on the seedlings. It is better to use a triangular knot to press the top (sun protection). This method can be applied in all types of transplants, especially for those dicotyledonous crops that are not easily relocated.
