Symptoms and control methods of green pepper cataplasia

Green pepper, also known as pepper, pepper, sea pepper, pepper eggplant, sweet pepper, belongs to the Solanaceae pepper crop, is an annual or perennial herb, cultivated all over the country, is the main traditional vegetable in our country. It is rich in nutrition, containing protein, organic acids, vitamins, pigments, capsaicin and calcium, phosphorus, iron and other minerals needed by the human body. It can promote appetite and help digestion. Its vitamin C content is very high. Green pepper tender fruit and mature fruit can be eaten fresh, green pepper flesh thick and crisp tender, rich in vitamin C. Green fruit contains about 93.9% moisture, about 3.8% carbohydrates, vitamin C; red ripe fruit contains up to 460 mg of vitamin C. Can be cold, fried, cooking, stuffing, pickling and processing cans, candied fruit.

Characteristics of Green Pepper

1. According to the fruit shape, chili peppers can be divided into five categories: cherry pepper, cone pepper, cluster pepper, horn pepper and lantern pepper.

2. The main root of green pepper is underdeveloped and the root quantity is small. Most of the root groups are distributed in the topsoil layer of 10murmur15cm, and the root system is neither drought-resistant nor waterlogging-resistant. The ability of root regeneration was weaker than that of tomato and eggplant. I can't stand thick fertilizer.

3. Flower drop, fruit drop and leaf drop (commonly known as "three falls") of hot pepper are also easy to occur, which is an important problem in pepper production and has a great impact on pepper yield.

The reasons for the "three falls" are complicated. Early spring flower drop is mainly caused by low temperature affecting pollination and pollen tube elongation; drought in soil and air is also the cause of flower drop; excessive or insufficient nitrogen fertilizer, excessive or insufficient branches and leaves, lack of light and other factors directly affect the balance between vegetative growth and reproductive growth. High temperature and drought lead to the occurrence of virus diseases, or high temperatures and floods weaken the absorptive capacity of roots, physiological disorders of plants, as well as diseases and insect pests (anthracnose, ring disease, cotton bollworm, night moth), causing a large number of "three falls".

Symptoms and control methods of quenching disease of green pepper

Symptoms of green pepper quenching disease:

The diseased part of the young stem showed waterlogged disease spot, the diseased part turned yellowish brown, and then constricted into a linear shape, causing the seedlings to quench or die. Due to the rapid development of the disease, the cotyledons of the seedlings have not yet withered, and the seedlings lodge rapidly when they are still green, that is, sudden collapse. The seedling bed caused the seedlings to collapse and die. White flocculent hyphae grow on the diseased seedlings or on the soil near the diseased seedlings at low temperature and humidity.

Prevention and treatment of green pepper quenching disease:

Select disease-resistant varieties; add soil ratio to Chong Road as base fertilizer; ventilate and control humidity; divide seedlings and seedlings early at the beginning of the disease, spray seedlings with iodine alginate to cultivate strong seedlings; 50% ammonium bromide 500 times solution soak seeds for direct seeding or wash them to accelerate sprouting; methyl topiramate wettable powder 800-1000 times solution mixed with flower and fruit doctors can calcium spray.
