What is the cause of dead pepper seedlings?

Pepper planting is very common in China, and the planting area is also very large. Although there are many people who grow chili peppers, there are often some problems when growing chili peppers. Among them, dead seedling is a very common one, which will seriously affect the yield of pepper and reduce economic benefits. So what is the cause of the death of pepper seedlings? Today, the editor will give you a brief introduction. Let's take a look at it.

1. Rainstorm and sudden sunny

When growing chili peppers, if the heavy rain suddenly clears up, especially in summer. Then the rate of soil water evaporation will be very fast, and because the soil water content is very large after the rainstorm, which leads to the lack of oxygen in the soil and the decrease of root absorption capacity. Therefore, the rate of water absorption in the roots is far less than that of evaporation, resulting in rapid water shortage of pepper plants and wilting of seedlings. This situation is also known as fake death, if the fake death state can not be restored as soon as possible, then all parts of the seedlings will be seriously short of water, resulting in the complete death of pepper seedlings.

2. Overwatering

Planting and watering chili peppers is essential, but if there is too much watering or if the soil accumulates water after heavy rain. Then it can easily lead to lack of oxygen in the soil, and the content of carbon dioxide will increase as a result. Resulting in soil reduction is too strong, but also easy to produce a variety of hydrogen sulfide poisons. It is very disadvantageous to the protoplasm of pepper seedling root. The absorption function of pepper root will also be inhibited, and the root is also prone to poisoning, retting and other adverse phenomena. But the seedling lacks the nutrition, the moisture, naturally also easy to appear the dead seedling phenomenon.

3. Poor disease resistance.

The disease resistance of pepper is usually not very strong, if the pepper is injured due to a variety of reasons in the process of pepper growth. For example, agricultural operations, strong winds and heavy rain cause plants to rub against each other and lodge. As a result, the disease resistance of chili will be greatly weakened, resulting in a greater chance of transmission in the Icefield Temple. If there is a hot and humid environment, it will also cause the rapid propagation of pathogens, which will lead to a large number of dead seedlings of pepper. Therefore, we must pay attention to the protection of pepper, reduce wounds, enhance the disease resistance of pepper, and reduce the phenomenon of dead seedlings.

4. Other reasons

In addition to the above reasons, the disease can also lead to infectious dead seedlings of chili peppers. For example, Rhizoctonia solanacearum, bacterial wilt and so on, the pathogen can spread through many ways, such as air, Rain Water and so on, which greatly shorten the development cycle of pepper and lead to a large area of dead seedlings. In addition, improper application of fertilizer will also lead to the death of pepper seedlings. When applying organic fertilizer, it is not fully mature or the concentration of the fertilizer is too high. It is easy to cause pepper seedling wilting, pepper metabolic function disorder, resulting in pepper seedling death and other adverse phenomena.

The above is a brief introduction to the cause of dead pepper seedlings. That's all for today's introduction. This article is for reference only. I hope it can help you all.
