Problems solved by technology

However, in the current high-grafting technology of walnuts, there are generally low survival rate, large rootstock grafting section, easy to rot and affect tree vigor, severe wind breakage after grafting, partial crown or drooping branches, slow crown formation, and tree vigor is easy to decline. And other issues

Embodiment 1

[0033] In December, select the mother tree of an excellent variety of walnut that has already bear fruit, and select the branches of the year that are robust, fully lignified, and free from diseases and insect pests. The thickness of the branches is 1.0-1.5 cm, the buds are full, and the pith is small. Cut the branches at 8-10 cm, quickly seal the cut with paraffin wax and yellow wax at a volume ratio of 3:1 at a temperature of 105 degrees Celsius, and then store the branches at 0-3 degrees Celsius.

[0034] From late March to mid-April every year, select 5-20-year-old walnut trees with little or no fruit bearing but vigorous growth and no pests and diseases. Choose 3-5 robust walnut trees with a thickness of 2-6 cm according to the tree shape and direction. The main branch is grafted; at the straight and smooth place within 15-50 cm from the main branch on the main branch, cut off the upper end, flatten the section with a sharp knife, do not damage the bark, peel off the old b...

Abstract

The invention discloses an adult-walnut-tree total-crown grafting method which solves the problems that the grafting cross section of a traditional adult-tree stump is large, the survival rate is low, and the crown recovery speed is low. The adult-walnut-tree total-crown grafting method includes the technical steps of rootstock selecting and processing, scion selecting and processing, grafting time determining, rootstock and scion cutting, grafting, after-grafting managing and the like. The adult-walnut-tree total-crown grafting method is high in grafting survival rate, negative effects on a tree body can be reduced, the tree vigor can be prevented from being early aged, the crown recovery speed is high, and the yield of a walnut low-yield forest is rapidly improved.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, in particular to a method for grafting walnut trees. Background technique [0002] Walnut is an important woody grain and oil tree species with a long history of cultivation. However, for a long time, forest farmers have mainly adopted the seed propagation method of walnut. The genetic traits are extremely unstable, the offspring vary greatly, the varieties are mixed, the quality is uneven, and the yield is low and unstable. It is difficult to bear fruit and less fruit to bear. [0003] It is the fastest and most effective way to improve walnut quality and walnut yield by adopting high-quality walnuts. However, in the current high-grafting technology of walnuts, there are generally low survival rate, large rootstock grafting section, easy to rot and affect tree vigor, severe wind breakage after grafting, partial crown or drooping branches, slow crown formation, and tree vigor is e...
