Pepper autumn delay cultivation field management method

Abstract

The invention discloses a pepper autumn delay cultivation field management method, comprising the following steps of (1) nutrient and water management: seedlings are watered once in 5-7days after filed planting so as to relieve the seedlings; (2) temperature and humidity management: shading and cooling measures are mainly taken in the earlier stage, so that the occurrence and propagation of virus diseases which are caused by high temperature and drying are prevented; (3) illumination management: after field planting and before blooming and fruiting, on the basis of capping an insect-proof screen, a sunshade net with 40-60% of sunshade rate still needs covering a greenhouse from 10a.m. to 16p.m. in a sunny day; (4) support erection: in order to prevent plants lodging and fruit spur dropping and breakage, supports are erected before blooming and fruiting; (5) plant and fruit adjustment: first grown pepper and lower lateral branches are removed in time, fruits which are formed by blooming in the end of October cannot grow up, and tips are removed in the end of October, so that formed fruits can be promoted to swell; (6) fruit bearing and storage: harvesting is carried out from the end of October to early November, and the harvesting of the fruits can be delayed through methods of reducing the temperature in the greenhouse and controlling water. The pepper autumn delay cultivation field management method is high-temperature-resistant, virus-resistant, strong in growth vigor, centralized in fruiting, and capable of fruiting a pepper variety with big fruits, thick pulp and more frigostabile property and increasing yield, the commodity grade can be improved, disease prevention is facilitated, the continuous selling of products is facilitated, the flower, fruit and leaf dropping of pepper is avoided, and the local economic benefit is greatly improved.

Description

technical field [0001] The invention relates to a pepper cultivation method, in particular to a field management method for autumn-delayed cultivation of peppers. 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...

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
