Pepper spring advanced cultivation field management method

Abstract

The invention discloses a pepper spring advanced cultivation field management method, comprising the following steps of (1) temperature adjustment: after field planting, plastic films tightly cover a greenhouse, and grass felts additionally cover the greenhouse at night; (2) watering and intertillage: after field planting and seedling survival, seedlings are water once more according to the soil moisture content, namely, the hardening of seedlings is carried out, and the intertillage is carried out for three times during hardening the seedlings; (3) topdressing: after field planting and before blooming, if the soil is lack of fertilizer, topdressing is carried out once, 10kg of nitrogen phosphorus and potassium compound fertilizer or urea are applied in every 667 square meters; (4) pruning and support erection: when first grown pepper is borne steadily, branches and lower lateral branches are all removed in time, the nutrition of main branches is prevented from being seized, and the development of fruits is not influenced; (5) growth regulator application: in the initial stage of blooming, a growth regulator is applied in order to prevent flower dropping and increase the fruit setting rate; (6) harvesting: the price of spring advanced pepper is higher in the early period, and the pepper can be sold in time when the market price is higher according to the growing condition of the fruits. The pepper spring advanced 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 early spring 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 t...

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
