Embodiment 1

[0017] Example 1: (1) Preparation of cuttings: In mid-to-late January, cut 1.0cm thick, full buds, robust, and highly lignified vegetative branches as scions; the collected scions were wax-sealed within 5 days: melting point 68℃ industrial paraffin wax and The beeswax is mixed in a ratio of 10:1, heated to 100-110℃, the scion is quickly dipped in the wax liquid for wax sealing, and the entire branch is required to be sealed; after the wax seal, the braid is boxed with air holes on both sides of the box; Store the cabinet in an environment with a temperature of 5-10℃ and a relative humidity of 75-85%;

[0018] (2) Selection of rootstocks for large trees: select the large iron walnut trees and miscellaneous walnut varieties that grow from the base after the death of the frost tree body, the tree age is 3-10 years, and the tree body is healthy;

[0019] (3) Grafting method:

[0020] 1. Grafting time: mid-March-early April grafting;

[0021] 2. Grafting technique: use splitting method,...

Embodiment 2

[0022] Example 2: (1) Preparation of cuttings: In early February, cut 2.0cm thick, full buds, robust, and highly lignified vegetative branches as scions; the collected scions were wax-sealed within 5 days: industrial paraffin and beeswax with a melting point of 68°C Mix according to a ratio of 10:1, heat to 100-110°C, quickly dip the scion in the wax liquid and wax seal, and seal the entire branch; pack the wax-sealed braid in a box, with ventilation holes on both sides of the box; The cabinet is stored in an environment with a temperature of 5-10℃ and a relative humidity of 75-85%;

[0023] (2) Selection of rootstocks for large trees: select the large iron walnut trees and miscellaneous walnut varieties that grow from the base after the death of the frost tree body, the tree age is 3-10 years, and the tree body is healthy;

[0024] (3) Grafting method:

[0025] 1. Grafting time: grafting when the new shoots are more than 30cm;

[0026] 2. Grafting technique: use splitting method, ...

Abstract

The invention belongs to the technical field of fruit tree cultivation and particularly relates to a novel grafting reformation method for large Yunnan walnut trees. The method is characterized in that the selection of scions and stocks, grafting time and a grafting technology are improved; by the adoption of technical means of grooving water drainage and delayed grafting, the grafting survival rate of the large walnut trees is remarkably improved. The method is simple to operate and easy to popularize.

Description

Technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and particularly relates to a new method for the transformation and grafting of large walnut trees in Yunnan. Background technique [0002] Walnut is one of the world’s important oil-bearing dried fruit species. Its kernels, branches and leaves, peel, seed shell, pollen and wood can all be used. Walnut kernels are especially famous for their rich nutrition and are of high value for comprehensive development and utilization. "Iron crops" and "money trees" are a fine perennial economic tree species. [0003] Yunnan Province is the origin and main producing province of my country's famous high-quality walnuts. With a planting area of ​​nearly 40 million mu, it has become an important green pillar industry in Yunnan mountainous areas, ranking first in the country in terms of yield and quality. However, in recent years, the production development in some areas has been too fast, and the probl...
