Abstract

Disclosed is a walnut which is an important dry fruit tree in China and has rather high economical and nutritive value and broad medical and health functions. The walnuts are widely distributed in China, however, the process of variety improvement is rather slow, the invention provides a walnut scion disinfection and mulching film moisture retention shading grafting method with simple operation and high survival rate for overcoming defects and shortages of the prior art. The invention has the technical proposals of walnut scion disinfection-cutting back and engraftment-rootstock treatment-cuttage tongue grafting-mulching film moisture retention-shading treatment-automatic scion bud bursting from the membrane. The invention has advantages of simple operation, short inoculation time, high seedling rate, high survival rate of over 90 percent, simple method, stable effects, more mature fine variety breeding technique of walnut and wide promotion and application areas compared with a plurality of current grafting methods.

Description

technical field [0001] The invention relates to a method for grafting fruit trees, in particular to a method for grafting walnut scions with sterilized mulching film for moisturizing and shading, which is asexual reproduction of fruit trees and belongs to the field of agriculture. Background technique [0002] Walnut is an important dried fruit tree species in my country. In the international market, walnut, almond, cashew nut, and hazelnut are collectively called the four major dried fruits. It has high economic and nutritional value and a wide range of health care functions. The distribution of walnuts in my country is very wide, except for the distribution in the northeast and the middle and lower reaches of the Yangtze River, it is distributed in other places. Due to its advantages in various aspects, it has taken a relatively large proportion in the conversion of farmland to forests in recent years. At present, there are more than 40 walnut varietie...
