Transplanting and grafting method for mango trees

Abstract

The invention relates to a fruit tree cultivating method, in particular to a transplanting and grafting method for mango trees. The method includes the steps that a seedling is lifted, the 5-10-year-old mango tree is transplanted locally, it is required that a bare root is provided with part of a main root and a lateral root, and in the seedling lifting process, only a trunk and a first-level branch are reserved; the mango afforestation tree transplanted from other provinces is planted, it is required that a bare root of the afforestation tree is provided with part of a main root and a lateral root, only a trunk is reserved in the seedling lifting process, and the height of the trunk ranges from 80 cm to 90 cm; the main roots and the lateral roots sprayed by rooting powder added with water are planted in a garden, then the trunks and the first-level branch are covered with mulch films, grafting is conducted within 20 days after planting, three scions are grafted on one trunk, or 1-2 scions are grafted to one branch. According to the method, the building speed of the mango garden is increased, the non-production period of the mango garden is shortened, the transplanted mango trees quickly enter a startup period, and the method is particularly suitable for being applied to Jinsha river dry-hot valley areas of late-maturing mango main producing areas, with low-temperature danger or cold damage in winter, in sub-suitable mango planting areas.

Description

technical field [0001] The invention relates to a method for cultivating fruit trees, in particular to a method for transplanting and grafting mango trees. Background technique [0002] The dry-hot valley area of ​​the Jinsha River is the main production area of ​​late-maturing mangoes in my country. The development area reached more than 500,000 mu by 2014. Due to the comparative benefits of planting mangoes, it is still developing rapidly. Due to the distinct rainy and dry seasons in this area, the rainy season is from June to October, and the dry season is from November to May of the following year, and there is a lack of water resources in the area. The mango planting area cannot meet the needs of irrigation. After the mango seedlings are planted, the survival rate is low and the growth is slow. Generally, 1-year-old seedlings are planted, and then grafted in the orchard after 2-4 years, and then put into production after 4-6 years, the yield is low, the non-production a...

Due to the distinct rainy and dry seasons in this area, the rainy season is from June to October, and the dry season is from November to May of the following year, and there is a lack of water resources in the area. The mango planting area cannot meet the needs of irrigation. After the mango seedlings are planted, the survival rate is low and the growth is slow. Generally, 1-year-old seedlings are planted, and then grafted in the orchard after 2-4 years, and then start production after 4-6 years. The yield is low, the non-production area is long, and the planting of mangoes is slow.

In addition, the dry-hot valley area of ​​the Jinsha River has a typical three-dimensional climate type. With the increase of altitude, the ripening period of the same mango variety gradually delays. The altitude of mango planting is constantly rising, from the original altitude of 1,400 meters to more than 1,500 meters, and some have exceeded 1,600 meters. Due to the increase in altitude, the temperature in winter is relatively low, and the ability of planted seedlings to resist low temperature damage or freezing damage is weak. Every year encounters different degrees of low temperature hazards, making it difficult to build a garden and the success rate is not high
