What causes pepper plant death
Pepper cultivation is very common in our country, and the planting area is also very large. Although there are many people growing peppers, various problems often arise during pepper cultivation. Among them, plant death is a very common one, and plant death can seriously affect pepper yield and reduce economic benefits. So what causes pepper plant death? Today, the editor will give you a brief introduction. Let's take a look below!
1. Sudden clearing after heavy rain
When growing peppers, if heavy rain is followed by sudden clearing, especially in summer. Then the soil moisture evaporates very quickly, and because the soil moisture content is very high after heavy rain, the soil becomes oxygen-deficient, and the absorption capacity of the roots decreases. Therefore, the water absorption rate of the roots is far slower than transpiration, causing the pepper plants to rapidly lack water, and the seedlings show a wilting state. This situation is also called false death. If the false death state cannot recover as soon as possible, then all parts of the seedling will be severely short of water, thus causing the pepper to completely die.
2. Excessive watering
When growing peppers, watering is essential, but if too much water is applied or water accumulates in the soil after heavy rain. Then it is very easy to cause soil oxygen deficiency, and the carbon dioxide content will also increase as a result. This causes the reducing effect of the soil to become too strong, and it is also easy to produce various toxic substances such as hydrogen sulfide. It is very unfavorable to the protoplasm of the pepper seedling roots. The absorption function of the pepper roots will also be inhibited as a result, and the roots are also prone to various adverse phenomena such as poisoning and root rot. And when the seedlings lack nutrients and water, it is naturally easy for plant death to occur.
3. Poor disease resistance
The disease resistance of peppers is usually not very strong. If the peppers are injured during growth for various reasons. For example, if agricultural operations, strong winds and heavy rain cause plants to rub against each other or lodge. Then the disease resistance of the peppers will be greatly weakened, leading to a greater chance of pathogen spread. If there is also a high-temperature and high-humidity environment, then it will also cause rapid reproduction of pathogenic bacteria, thus triggering a large number of pepper plant deaths. Therefore, everyone must pay attention to doing a good job in pepper protection, reducing wounds, enhancing the disease resistance of peppers, and reducing plant death.
4. Other reasons
In addition to the above reasons, diseases can also cause infectious plant death in peppers. For example, damping-off and bacterial wilt, etc. There are many ways pathogens can spread, such as air and rainwater, etc., causing the pepper development cycle to be greatly shortened, thus triggering large-scale plant death. In addition, improper fertilizer application can also cause pepper plant death. When applying organic fertilizer, if it is not fully decomposed or the fertilizer concentration is too high. It is easy to cause pepper seedlings to wilt, disrupt the metabolic function of peppers, and cause various adverse phenomena such as pepper plant death.
The above is a brief introduction to what causes pepper plant death. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
