Efficient peach tree seedling culture method

Abstract

The invention discloses an efficient peach tree seedling culture method. The method comprises the following steps that S1, a seedling culture substrate is stirred and disinfected by using an aqueous solution of potassium permanganate and covered with a plastic film for 45-52 hours, and a rooting agent and a plant growth regulator are added for use, wherein the plant growth regulator is a pesticideplant growth regulator with the effective components including flumetralin and paclobutrazol; a branch with the diameter of 7-10 mm is selected from branches which are 25-32 cm away from a main branch on a peach tree, bark with the length of 2-5 cm is stripped, the substrate is wrapped with a plastic film, the water content of the substrate is 50-65%, and the substrate is tightly tied to be isolated from air; S3, after the branch is processed, the branch takes root 20 days later, the lower end of a tied portion is cut off 120 days later, the plastic film is removed, and the branch is soaked in a nutrient solution for 10 minutes and then planted in soil, wherein a rooting agent is an ABT1 rooting agent. The method is low in cost and convenient to operate and rootstocks are not needed, so that the cultivation period is greatly shortened, the seedling culture efficiency is improved, and the method can be popularized in a large area.

Description

technical field [0001] The invention relates to the technical field of nursery stock cultivation, in particular to a method for efficiently cultivating peach tree seedlings. Background technique [0002] Peach, Rosaceae, Peach, is a small deciduous tree whose fruit is used as a fruit. The flowers are ornamental and the fruit is juicy.

Problems solved by technology

[0003] The propagation methods of peach trees include sowing, cutting, grafting, layering, etc. Among them, the method of raising seedlings by cutting is the most commonly used method, but improper handling will lead to low rooting rate of cuttings

There are also a lot of seeds that are used to propagate and raise seedlings, but the seeds germinate slowly, and the seeds germinate 20-40 days after sowing. to satisfy the market's needs
