All-branch grafting method for fruit tree

Abstract

The invention discloses a full-branch grafting method for a fruit tree and belongs to the technical field of agriculture. The method comprises the following steps: (1), scion selection and storage, wherein the scions are collected and are subjected to moisture-holding storage at a low temperature after being sealed by wax; (2), old tree shaping, wherein the tree is shaped at the height of 2.5-3.5 m, unwanted side branches are removed, and 3-5 important main branches are reserved; (3), punching, wherein punching is performed at the smooth part of a selected big tree trunk or a principle branch side surface with the scion interval of 19-21 cm; (4), grafting, wherein the well cut scion is inserted into a stock notch by the right hand to reach an extent that the lower end of the scion is propped against the bottom of the stock notch, and the scion and the stock are in alignment and close contact on two surfaces; (5), binding up, wherein a layer of mulching film plastic cloth is bound up at the scion part, and two layers bound up at the non-scion part; and processes such as bud picking, water fertilizing, wind protection, disbranching, spraying and insect prevention are carried out after grafting. According to the invention, the grafting technology has the advantage that the fruit bearing area of the old tree is increased, and also has the advantages of high survival rate, thriving tree vigour, high yield, quickness in shaping, simplicity in maintenance and the like.

Description

technical field [0001] The invention relates to a method for grafting whole branches of fruit trees, which is suitable for peaches, apricots, pears, apples and other varieties, and belongs to the field of agricultural technology. Background technique [0002] The renewal of fruit tree varieties is an important link in the development of modern agriculture. In recent years, its update speed has shown an accelerated trend. The new varieties have high prices and good benefits, and are deeply loved by fruit growers and consumers. However, this also brings another problem, that is, whether the old varieties of orchards will stay. Due to the lack of suitable grafting techniques, many farmers cut down old fruit trees in a short-sighted manner. , Planting new varieties has resulted in a huge waste of resources and has also greatly damaged the ecological environment. The examples of cutting hawthorn trees and apple trees in the past few years are not uncommon. How to enable fruit f...

Problems solved by technology

[0003] In the past, the grafting of new varieties was usually "high grafting and head replacement", that is, grafting new varieties on the top of the branches of old fruit trees in order to increase the yield, but it often backfired. Due to too few grafting points, the photosynthesis of the trunk and its own Contradictions in growth can easily lead to poor tree vigor, slow growth in two or three years, and even the danger of dead trees. Therefore, in recent years, fruit farmers seldom use grafting to update varieties, and most of them cut down old trees and plant new ones. According to incomplete statistics, in the first 5 years of apple variety renewal in Jinan City, fruit farmers cut down nearly 100,000 mu of fruit trees and planted new red Fuji apples. Therefore, it is difficult for everyone to see Xiao Guoguang and Da Guoguang now. Wait for the variety
