Embodiment Construction

[0022] The present invention will be described in detail below in combination with specific embodiments.

[0023] The present invention provides a kind of red mango high crown replacement method, comprising the following steps:

[0024] 1. Grafting treatment,

[0025] (1) Trunking and cultivating rootstocks. Mango trees around 10 years old are not easy to graft because the trunk is too thick. For this type of tree, they should be cut at a height of 1.2-1.5 meters from the ground, and the original trunk and main trunk should be kept. For a section of the branch, after the main branch sprouts, select 3 healthy and reasonably distributed branches for each main branch, and the rest should be erased as soon as possible. The cutting time is about August after the fruit is picked. The method is to use a saw to cut off the branches so as not to tear the branches. Mango trees in the age of 4-6 have small main branches, which can be directly grafted on the main branches without cuttin...

Abstract

The invention discloses a top grafting canopy replacement method of red mangoes. The specific method comprises the steps of grafting treatment and management after grafting, and carries out the technologies of scion collection and grafting. By adopting the method, the variety can be continuously improved and is quick in upgrading, and newly selected good varieties can be timely grafted on existing trees at any time; the mango trees have strong root systems and adequate nutrition, thereby facilitating the quick growth of canopies. Therefore, if grafting and canopy replacement are finished in the first year, the trees can bear fruit the next year; compared with the method of replanting trees, the method can shorten the immaturity period by about two years; mature, inferior and low-yielding production orchards are transformed into high-yielding, superior orchards with high economic profits in a short time.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for high grafting and crown replacement of red mangoes. Background technique [0002] Ledong County is a well-known mango county in Hainan Province. It has a long history of growing mangoes. There are more than 30 varieties of mangoes. The existing mango planting area is more than 60,000 mu, with an annual output of more than 17,000 tons. It is mainly sold to Beijing, Wuhan, and Shanghai. , Yunnan, Guizhou, Sichuan, Xinjiang, Guangzhou, Qingdao and other provinces and cities. In recent years, due to the messy mango varieties in Ledong County, high-quality mangoes cannot be planted on a large scale. The long tree is tall and tall, and the crown is too dense, resulting in a decrease in yield and quality, which affects the efficiency of the orchard, causing some mango enterprises and fruit growers to destroy trees and replant other crops. In view of t...
