The latest green pepper leaf curl. What's going on?

Green peppers are planted in spring and harvested in summer. Chili peppers are usually planted in farmers' homes, but sometimes there are some minor problems, such as the leaves of green peppers are curly, which may have been very good before, but suddenly one day I found that the leaves of green peppers were curled. What is the reason for this? let's take a look at the specific reasons and how to effectively prevent this phenomenon.

1. Lack of water

When soil moisture is missing, the root system will lose water and dry up, and it will also lose its absorptive capacity, and the root system will not absorb too much water, then the leaves will be short of water, the plants will be short of water, and eventually the leaves will be curled because of the loss of water. In this case, it is best not to touch the leaves. You can water them in time when the transpiration is small in the evening, but don't water so much at first and gradually return to normal watering.

2. High temperature

If you enter the summer, the external high temperature, transpiration is very large, and the soil temperature will also rise, if there is a lot of soil moisture at this time, it is easy to boil the roots, if there is no water, the leaves will be curled to reduce transpiration to ensure that the leaves will not wither. For this reason, it is best to control the temperature at any time, sometimes you can build a sunshade net, or cover other items to cool down, if the greenhouse planting temperature will be easier to control.

3. Virus disease

Pepper can be infected with a variety of viral diseases, many viral diseases will cause leaf wrinkling, curling, but the symptoms after infected with viral disease are more obvious, it is easy to identify whether infected with viral disease caused leaf curling, if so, timely treatment, this is not just a problem of leaf curling, it is best to use corresponding agents to control the disease and eliminate the virus. But spray should pay attention to the use of concentration, do not damage the leaves.

4. Insect pests

Insects such as aphids, planthoppers, you, and mites all suck the sap of leaves or plants, and spread viral diseases at the same time. It is found that these worms are usually larvae clustered on the back of leaves or branches. As soon as they are found, they can be brushed away and collected in containers. Finally, put the pesticide water agent directly to death. Then the entire planting area should be sprayed with chemicals, including ridges.

5. Improper management

Sometimes insufficient soil nutrition, little fertilization, lack of nutrition, will also produce leaf curling phenomenon, if there is little humus, a lot of nitrogen fertilizer, pepper plant growth resistance decreases, there is no resistance, adaptability is very weak. Therefore, in addition to choosing suitable soil, we can also apply more mature farm manure, deciduous soil and so on. Use less chemical fertilizer and nitrogen fertilizer alone.

Green pepper leaf curl is mainly due to these reasons, in fact, there may be other reasons, everything should be judged according to the actual growth, focusing on preventing aphid damage and virus diseases, the two are closely related. Lack of water and high temperature are physiological reasons, which need to be paid attention to.
