Embodiment 1

[0018] A method for cultivating peach seedlings in facilities and cultivating flowers, using a mixture of peat, vermiculite, sand and cow dung as a substrate, the volume ratio of peat, vermiculite, sand and cow dung used is 3:0.8:0.8:0.5, and a small amount of auxiliary application Bag-controlled slow-release fertilizer, N:P in the bag-controlled slow-release fertilizer 2 o 5 :K 2 O=2:1:2, use cloth bags or root control devices as root-limiting containers, plant 1-year-old peach seedlings at 60 cm to dry; when the new shoots grow to 10 cm, the top is topped, and the branches are 10 cm long before topping; from 6 From the beginning of the month, spray 0.3% urea and 0.3% potassium dihydrogen phosphate once every 10 days; from the beginning of July, use a 2.5cm wide plastic strip to tightly wrap the trunk 3~4 times at the 10cm point of the grafting joint and bind it once , restrict the transport of tree nutrients to the roots, and promote the formation of flower buds on the bra...

Embodiment 2

[0020] A kind of method of cultivating peach facility cultivation into flower seedling, with bag or root control device as container, cultivation substrate is the mixture of peat, vermiculite, sandy soil and cow dung, the volume ratio of used peaty charcoal, vermiculite, sandy soil and cow dung is 5: 1.2:1.2: 1.5, a small amount of bag-controlled slow-release fertilizer is applied, and N: P in the bag-controlled slow-release fertilizer applied 2 o 5 :K 2 O=2:1:2, plant ordinary 1-year-old peach seedlings among them, fix the stem at 60cm~70cm, cultivate the main trunk to form a tree shape; when the new shoot grows to 10cm, the top is topped, and the branches are extended by 10cm before topping; from 6 From the beginning of the month, spray 0.3% urea and 0.3% potassium dihydrogen phosphate once every 10 days; from the beginning of July, use a 2.5cm wide plastic strip to tightly wrap the trunk 3~4 times at the 15cm place on the grafting joint and bind it once , restrict the tra...

Embodiment 3

[0022] A kind of method of cultivating peach facility cultivation into flower seedling, with bag or root control device as container, cultivation substrate is the mixture of peat, vermiculite, sandy soil and cow dung, the volume ratio of used peaty charcoal, vermiculite, sandy soil and cow dung is 4: 1:1:1, supplementary application of a small amount of bag-controlled slow-release fertilizer, N:P in the bag-controlled slow-release fertilizer 2 o 5 :K 2 O=2:1:2, plant ordinary 1-year-old peach seedlings among them, fix the stem at 60cm~70cm, cultivate the main trunk to form a tree shape; when the new shoot grows to 10cm, the top is topped, and the branches are extended by 10cm before topping; from 6 From the beginning of the month, spray 0.3% urea and 0.3% potassium dihydrogen phosphate once every 10 days; from the beginning of July, use 2.5cm wide plastic strips to tightly wrap the trunk at 10cm and 20cm on the grafting interface for 3~4 Bind two loops to limit the transport...

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...
