A kind of capsicum leaf pruning method

Abstract

The invention belongs to the field of plant culturing, and relates to a pepper whole-twig leaf picking method. The method comprises the steps that when the length of a lateral twig below a dichotomousbranch of the stem of a pepper plant reaches 1-6 cm, the lateral twig is smeared, and smearing is conducted for once every 2-8 days until there exists no germinated lateral twig below the dichotomousbranch of the stem; when a cotyledon starts becoming yellow, 2-5 pairs of true leaves above the cotyledon on the stem are removed; 2-5 pairs of blades of the true leaves from top to bottom are removed when a pair of true leaves left at the downmost position on the stem become yellow; all true leaves below the dichotomous branch of the stem are removed when a pair of true leaves left at the downmost position on the stem become yellow. The method has the advantages that the operation is convenient, a plant group structure can be improved to improve the ventilation and light transmission performance of the parts, close to the ground, of plants and reduce air humidity, the photosynthetic efficiency is improved, the plants can grow and develop to be more robust, plant diseases and insect pestscan be effectively controlled to increase the percentage of fertile fruit, lateral twigs and blades located below the dichotomous branch of the stem can be removed in batches, and therefore the influence on the growth of the plant is small.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and relates to a method for pruning and picking leaves, in particular to a method for pruning and picking leaves of peppers. Background technique [0002] Due to resource constraints, there is constant competition for resources such as light, heat, water, and fertilizer between plant individuals and internal organs in nature. The purpose of agricultural production is to obtain agricultural products with good yield and quality. It is a waste for plants to produce too many organs. Artificial pruning, pruning and removal of some leaves and side branches of plants can reduce redundant growth and ensure healthy growth of plants. development. [0003] In nature, due to the luxuriant branches and leaves of the plants, they shade each other, resulting in poor ventilation and light transmission near the ground, high air humidity, and easy to form conditions for disease prevalence; in addition, the leaves...

AI Technical Summary

Problems solved by technology

Among them, after the door pepper reaches 5 maturity, it is more used to remove all leaves and side branches on the main stem at one time, but when the door pepper reaches 5 maturity, the side branches on the main stem are relatively large, which consumes a large amount of assimilation products. Remove all the leaves on the main stem at one time. The lower leaves are old and easy to become a channel for pathogens to invade, while the middle and upper leaves are still strong and can perform photosynthetic functions. If they are removed too early, the photosynthetic capacity of the plant will be affected; in addition, the leaves on the main stem Side branches will also germinate and grow, affecting ventilation and atmospheric humidity, resulting in a high incidence of diseases

[0006] CN201210335450.7 discloses a method for pruning capsicum indefinitely. The method first "topping or twisting" the side branches on the main pole only interferes with the growth of the side branches, but does not remove the side branches; but waits until the middle and late stages of growth, All the side branches are removed, which affects the ventilation and light transmission of pepper plants in the early stage of growth to a certain extent, and increases the risk of disease occurrence; and increases the labor cost by "picking or twisting branches" in the early stage and "extracting" in the later stage.
