Pepper overwintering cultivation field management method

Abstract

The invention discloses a pepper overwintering cultivation field management method. The method comprises the first step of temperature management, wherein a shed is closed and temperature rises after field planting, the daytime temperature should be controlled between 26 DEG C and 30 DEG C, the night temperature should be controlled between 18 DEG C and 20 DEG C, and generally the rejuvenation can be achieved in 6-7 days; the second step of illumination management, wherein after December, as outside illumination time is shortened and the illumination intensity is weakened, a better-off farmer can hang a reflective curtain on the back wall to improve the illumination inside the shed; the third step of water and fertilizer management, wherein after the field planting and rejuvenation are achieved, the temperature inside a greenhouse is low, the evaporation capacity is low, the frequency of watering should be low as much as possible, and if the day is droughty, watering should be carried out in the mornings in the fine days; the fourth step of disease and pest prevention and cure, wherein peppers should be prevented from developing viral diseases, the scab, the bacterial wilt and the anthracnose, and should be prevented from being affected by polyphagotarsonemus latus, cotton bollworms and oriental tobacco budworms. According to the pepper overwintering cultivation field management method, the pepper species which is high-temperature resistant, antiviral, strong in growth vigor, big in fruits, thick in fruit flesh and cold resistant is provided, the fruits are centralized, the yield can be increased, the grade of the peppers can be improved, diseases can be prevented, the peppers can appear on the market continuously, the phenomena of flower dropping, fruit dropping and leaf dropping of the peppers can be avoided, and local economic benefits are greatly improved.

Description

technical field [0001] The invention relates to a pepper cultivation method, in particular to a field management method for overwintering pepper cultivation. Background technique [0002] Capsicum, also known as hot pepper, sea pepper or pepper eggplant, is native to Central and South America. It has erect stems and alternate single leaves. It is an annual plant in artificial cultivation. It can be divided into cherry peppers, cone peppers, clustered peppers, long There are five types of peppers and bell peppers. When the main stem grows 8-10 leaves, the first flower will be born, and the requirements for temperature and humidity are wider than those of tomatoes and eggplants. [0003] (1) Features [0004] 1. The main root of pepper is underdeveloped and the amount of roots is small. Most of the root groups are distributed in the topsoil layer of 10-15 cm. The root system is neither drought-tolerant nor waterlogging-resistant. Root regeneration ability is weaker than that...

AI Technical Summary

Problems solved by technology

[0006] 3. High temperature and drought induce the occurrence and spread of viral diseases, and high temperature and rainy conditions often lead to the prevalence of viral diseases

[0007] 4. Pepper flower drop, fruit drop and leaf fall (commonly known as "three fall") are also prone to occur. This is an important problem in pepper production and has a great impact on yield

[0011] 3. Water content: The water requirement is not too high, but the root group is underdeveloped, and the soil is not kept moist frequently, so it is difficult to obtain high yields
