Technology for cultivating florescent large seedlings of peach protected cultivation

Abstract

The invention discloses a technology for cultivating florescent large seedlings of peach protected cultivation. A cloth bag or a root control device is taken as a container; culture substrate is the mixture of turf, vermiculite, sandy soil and cow dung; a small amount of bag-control slow release fertilizer is auxiliarily applied; common one-year peach seedlings are planted in the substrate; from earlier June, 0.3% of urea and 0.3% of monopotassium phosphate are applied to the leaf surface once every 10 days; from earlier July, plastic strips the width of which is 2.5cm are wound tightly around the main stems for 3-4 rounds and are bound for once to twice at 10-20cm on grafting unions, so as to limit the transportation of tree body nutrition to roots and promote the formation of flower buds on branches. The invention provides the technology for cultivating peach seedlings used for peach protected cultivation with more growth, branches and flower buds for production and solves the production technical problems of peach seedlings which have high yield in the same year in which the seedlings are planted.

Description

technical field [0001] The invention relates to a method for cultivating peach seedlings under protected cultivation into large flowering seedlings. The cultivated peach seedlings can be planted in the same year and bear fruit in the same year, thereby improving the early benefits of protected cultivation of peaches. Background technique [0002] Peach is a perennial deciduous fruit tree of the subgenus Prunus in the Rosaceae family. Its fruit is soft and juicy, and has a pleasant flavor. It is a popular fruit. Peach fruit has high nutritional value. It is rich in many candy gums and contains various vitamins and mineral elements, especially high iron content. It is not only a fruit suitable for all ages, but also beneficial to women and children. [0003] The peach seedlings currently cultivated in production are mainly one-year-old seedlings, which cannot be planted in the same year and have a high yield in the same year; there are few technologies for facility cultivation...

AI Technical Summary

Problems solved by technology

[0008] Adopt the method of above-mentioned 1~4, higher technical level is required to the producer, and the peach seedling branch of cultivating is not ideal, and flower bud quantity is less

For technology 3, spraying paclobutrazol on the tree body is faced with the problem of suspicious chemical residues; the ring cutting treatment adopted in technology 4 increases the risk of tree gum flow and pathogen invasion
