Cultivating method of grape seedlings

Abstract

The invention discloses a cultivating method of grape seedlings. The cultivating method comprises the following steps that 1) a sunshelter is built; 2) river sand is permeated into 1 / 4-1 / 3 soil in the sunshelter, a bed is finished, and the bed is 0.8-1.3 meters wide and 15-25 centimeters high; 3) semi-lignification summer tender tips more than 0.4 centimeter thick are collected to be cut into 3-4 sections of branch sections 20-30 centimeters long, the uppermost leaf is reserved, and a cutting panicle is obtained; 4) the cutting panicle is socked for 1-2 hours, then the root of the cutting panicle is socked and dipped into a rooting agent for 5-10 seconds, and cutting of the panicle is vertically carried out according to an array pitch of 20-30 centimeters and a planting distance of 10-15 centimeters; 5) humidity in the sunshelter is kept to be more than 90%, the temperature is kept to be 20-25 DEG C, and fertilization is carried out after rooting; when roots of the cutting panicle are 3-5 in number and more than 5 centimeters long, sunshading is stopped; tips are bound when the cutting panicle is 25-35 centimeters high, and pinching is carried out when the cutting panicle is more than 50 centimeters high. According to the cultivating method, the conditions of a high temperature, rapid growing and a great number of green branches in summer are utilized to carry out green branch cutting, the survival rate is up to 80-90%, and when the seedlings reach 40 centimeters high, the purpose of grape seedling intermediate propagation can be realized.

Description

technical field [0001] The invention relates to a method for cultivating grape seedlings, which belongs to the technical field of green branch cutting. Background technique [0002] The cultivation and propagation methods of grape seedlings mainly include three methods: cutting, grafting and layering. Among them, cuttings and grafting are the most common. Cuttings, also known as cuttings and cuttings, are one of the propagation methods used by plants. Simply put, a section of plant is inserted into a certain substance to make it take root, germinate, then grow, bloom, and bear fruit. It is to obtain the characteristics of the original plant. The most effective method of consistency is also used in order to protect this feature due to variation in a certain branch of the plant. The conditions required for cuttings are very high. If the cultivation method is improper, it will easily cause the growth of grape seedlings to be weak, which will affect the quality and harvest of ...
