How to prevent cucumber from appearing

Cucumber bent melon is also called malformed melon, which is a physiological disease. The reasons for causing cucumbers to bend melons are as follows:

First, excessive leaf picking is easy to cause cucumber bending; second, too many single plants in the early stage; third, small flowers in the ovary when flowering, long quality is not good, even if flowering, the nutrients obtained later are less, easy It causes the curved melon; the fourth is the normal long-fruited melon strip, which takes a certain time when the fruit is inflated. If the condition is slightly bad, it will form a curved melon. Therefore, it is very important to use fertilizer in the later stage. Fifth, the initial growth of the results is normal melon, if the nutrients can not be supplied in time, will soon form a curved melon; sixth is the long fruit cucumber formed, when encountered in the expansion of the leaves encountered obstacles, will also form curved melon; It is caused by potassium deficiency and boron deficiency caused by high temperature. Generally, the daytime temperature should not exceed 32 degrees, and the daytime should be controlled between 25-30 degrees. Eight is sometimes too much or a single use of nitrogen fertilizer or chicken manure, pig cow dung, potassium fertilizer, phosphate fertilizer is insufficient, and cucumber cucumber is also prone to occur. Or other malformations.

Prevention and treatment methods: First, do not prematurely remove too much of the bottom leaves. The yield of cucumber depends mainly on the photosynthesis of the leaves to increase the yield. As long as the bottom leaves do not yellow, generally do not remove them too early, unless the bottom leaves are functionally prematurely aging, they can be removed.

In order to prevent premature senescence of cucumber leaves, it is necessary to use NPK and microbial fertilizers as well as multi-element mineral fertilizers and organic fertilizers in fertilization. In the early stage, organic fertilizers and NPK fertilizers have been used in the base fertilizer, and now it can be used per mu. 20 kg of microbial agents and 20-30 kg of multi-element mineral fertilizer were applied to promote the growth of cucumber roots, supplement nutrients, and prevent cucumber roots and premature senescence of leaves.

The second is: watering should be diligent, but the amount of watering should be less. The interval between watering in the high temperature period should not be too long. Do not exceed 32 degrees during the day. Generally, the daytime control is between 25-30 degrees;

The third is: the yield per plant cannot be too high, and the excessive yield per plant will increase the burden on the plant. In the early stage, if the melon is too much or the melon is not picked up, the leaves will age quickly and the bent melon will be formed easily.

The fourth is: timely removal of the bent bones that have occurred, you can also use the small stones to climb the bottom to make it straight; the other leaves can spray 200 times liquid compound microbial fertilizer or Shuofeng 481, spray once every 7 days 2-3 times, it has good control effect on the prevention and treatment of curved melon, sharp melon and big belly melon.
