Pepper is a favorite vegetable for many people. In rural areas, there are not many farmers who grow pepper. However, in the process of planting peppers, we often find that some of the pepper leaves are rolled up, which affects the quality of the pepper. So, what is the cause of the pepper roll? How to prevent it?
1. Physiological factors lead to
Performance: The physiologically induced pepper leaf is mainly characterized by the leaves rolling up, and also thickening and hardening, the photosynthesis is weakened compared to the normally stretched leaves.
the reason:
1. The soil environment is relatively dry and the planting environment is relatively dry;
2. Usually use too much nitrogen fertilizer, caused by the lack of other trace elements in the soil.
Control method:
Reasonable watering management keeps the surface of the soil moist, properly ventilates, and immediately replenishes various trace elements.
2. Fertilization and medication lead to
Reason: Spraying pesticide or foliar fertilizer directly on the leaves of pepper, but the pepper leaves are rolled up due to inaccurate concentration or operation time.
Control method: water spray on the leaves, usually need more than three times, clean and dilute the pesticide on the surface of the pepper leaves to reduce the phytotoxicity.
3, the field appears in the Hummer
Reason: The presence of thrips in pepper cultivation also affects the surface of the plant. This is mainly because the thrips cause damage by sucking the juice on the leaves, so the problem of capsicum leaves is prone to occur over time.
Prevention and treatment methods: timely use of drugs, can be used in the parts of their regular activities, especially the back of the leaves should not be ignored.
4, sassafras caused
Reason: Most of the sassafras are gathered on the back of the leaves, and the flower buds and young fruits are in different positions. After the leaves are damaged, most of them are rolled up.
Control method:
1. Clear field weeds and litter in a timely manner;
2. Preferred healthy seedlings.
The above is the analysis of the reasons for the leaf rolling up during the pepper planting process and the comprehensive prevention and control technology compiled by Huinong. I hope to help you.
