Problems solved by technology

[0002] In recent years, with the continuous development of the walnut industry and the continuous emergence of new varieties, it has become an urgent task for the walnut industry to renew young young trees and low-quality and low-yielding walnut trees. In addition, the investment in rebuilding the garden is also a factor that cannot be ignored. Using high-grafting, on the original seedlings and low-quality and low-yielding trees, good varieties are grafted in batches in a planned and purposeful manner. It can maintain a certain yield, and can regenerate improved varieties, and high-grafting can produce early results and high yields. However, in mountainous areas with low temperatures, due to the abnormal climate in recent years, the survival rate of walnut tree grafting is lower, which seriously restricts high-grafting. Normal development of excellent walnut trees

Embodiment 1

[0016] Select a batch of seedling, low-quality, and low-yield walnut trees less than 12 years old, and use the following high-quality replacement method for operation:

[0017] 1. For the collection of scions, before the tree body germinates in early spring, select the excellent mother tree for picking ears, and collect the scions from branches that are free from diseases and insect pests, have a strong growth and a small pith center, and have a thickness of more than 1-1.2 cm. The cut of the mother tree is immediately sealed with paint, and the two ends of the scion are sealed with wax, and stored in a rural cellar at minus 3 to zero degrees;

[0018] 2. Grafting. The grafting time is on April 13th. The grafting method specifically includes (1) Draining water, sawing 2-3 saw cuts on the trunk of the tree to be grafted, in a spiral staggered miter saw, and the depth is 5 One part; (2) Scion cutting, select the fresh and substantial scion stored in step 1, cut it 12-15 cm long,...

Abstract

The invention relates to a method for high grafting and head change of walnut trees. The method comprises the following steps: collecting scions, grafting, removing unwanted sprouts, letting in fresh air, binding rods and a support, performing flower thinning, pruning and trimming, and protecting seedlings from cold. The grafting survival rate of the method for high grafting and head change of walnut trees reaches up to more than 95%, and wound healing is fast, operation is convenient, and grafting efficiency is high, and can improve drought resistance ability. The method is early in fruiting, early in high yield, good in branching ability, high in fruit spur fruit setting, compact in branches, and convenient in management.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for replacing high-quality walnut trees with high-quality ones.
