What is the latest yellow pepper leaf?

Pepper is a very common vegetable in our life. The market demand in China is also very large, and basically there are cultivation all over the country. When we plant chili peppers, we often encounter many problems that affect the yield of chili peppers. Especially in the pepper seedling stage, and the leaves yellowing is one of them. So what is the reason why the leaves of pepper seedlings turn yellow? The following editor will give you a brief introduction, let's have a look!

1. High temperature and drought

After the pepper seedlings were planted, their roots were still in a fragile state. Therefore, we need to promote the squatting of pepper seedlings through water and fertilizer management, but if we are in a hot and dry environment, then the absorption of water and fertilizer in the roots of pepper seedlings will be affected, resulting in yellow leaves in the lower leaves of the plant due to malnutrition. If it is caused by this reason, then we should properly spray foliar fertilizer and timely watering to slow down the seedlings as soon as possible. Especially in summer, it is very easy to have high temperature yellow leaves, so we must pay more attention to it.

2. Nitrogen deficiency and magnesium deficiency

Pepper seedlings in the growth process, the demand for nutrition is relatively large, if the lack of some kind of nutrition, then it is easy to have a lot of problems. If the pepper is short of nitrogen, the plant will be thin, low, and the leaves will be thin, small and yellowed, and in severe cases, the leaves will fall. Therefore, we should pay attention to the application of nitrogen fertilizer, but not too much, to avoid the excessive growth of chili peppers. Magnesium deficiency can also lead to yellow pepper leaves, which usually occur at the beginning of fruit, and the veins of the old leaves gradually turn yellow, and then gradually spread to the whole leaf along the vein. If you are short of magnesium, spray solutions such as magnesium sulfate every other week or so.

3. Potassium deficiency and calcium deficiency

In addition to nitrogen deficiency and magnesium deficiency, potassium deficiency is also a major cause of yellow leaves in pepper. If the pepper plant is deficient in potassium, it will gradually lose the green and yellow leaves from the leaf edge. And the leaves in the middle of the plant will gradually yellowing, at this time to properly spray twice potassium dihydrogen phosphate, can also increase the proportion of potash fertilizer when topdressing. Finally, calcium deficiency will also cause the upper leaves of the plant to turn yellow, and the plant will be dwarfed as a result. The leaves around the growing point of the plant gradually stop growing and die in severe cases. If this happens, spray calcium chloride every five days or so.

4. Drug damage and fertilizer damage

When planting pepper for fertilization, if the dosage is improper, then the plant is very easy to produce drug damage and fertilizer damage. If it is not treated in time, the yield of yellow leaves will be reduced, and heavy will lead to death. Pepper leaves will be scorched and yellowed after drug damage, but there is no expansibility. After the occurrence of fertilizer damage, pepper leaves will appear yellowing, atrophy and other phenomena. Therefore, when suffering from fertilizer damage and drug damage, we should pay attention to timely watering for dilution, and we can also apply appropriate amount of foliar fertilizer or growth regulators, and then carry out mid-ploughing work and take remedial measures.

The above is a brief introduction to the reason why the leaves of pepper seedlings turn yellow. That's all for today's introduction. This article is for reference only. I hope it can be helpful to everyone.
