Fruit tree grafting method

Abstract

The invention discloses a fruit tree grafting method which includes the steps: firstly, collecting scions, selecting and culturing grafted branches in a growth period of fruit tree branches, and cutting off the grafted branches in a dormant period of fruit trees; secondly, preserving the scions, sealing one end of each cut branch by the aid of wax liquor, enabling the other end of the branch to be inserted into nutrient solution of the fruit trees, and sealing the end surfaces of the branches by the aid of wax liquor after the branches absorb a certain nutrient solution of the fruit trees; thirdly, grafting the scions, obliquely cutting rootstocks, cutting off woodiness in the obliquely cut rootstocks, obliquely cutting one side of each grafted branch, cutting off surface layers of the other side of the grafted branch, and enabling the grafted branches to be inserted into obliquely cutting ports of the rootstocks; finally, performing wrapping. According to the method, the grafted branches are cultured, the cut grafted branches are soaked into the nutrient solution of the fruit trees, vitality and health of tree buds needed by grafting are ensured, grafting success rate and effect after grafting are ensured, and a grafting period is shortened by increasing contact area between grafting surfaces and grafting skins.

Description

technical field [0001] The invention relates to the field of cultivation and production, in particular to a method for grafting fruit trees. Background technique [0002] Fruit tree grafting is one of the methods of asexual reproduction of fruit trees, that is, to take branches or buds on a plant of a good variety and connect them to an appropriate part of another plant, so that the two can be combined to form a new plant. The connected branches or buds are called scions or buds, and the plants connected to the scions or buds are called rootstocks. Adopt the new plant of grafting propagation, promptly can keep the excellent character of its mother plant and can utilize the advantageous characteristic of stock.

Due to the uneven growth of the branches before the dormancy period, the buds on some branches have not strong v...

Problems solved by technology

[0003] At present, the grafting strips used in the fruit tree grafting process are the branches cut on the fruit trees during the winter dormancy period. Due to the uneven growth of the branches before the dormancy period, the buds on some branches have not strong vitality, and the nutrients contained in the branches Insufficient, the tree buds with weak vitality have a slow survival process after grafting and are prone to graft failure. Insufficient nutrients contained in the branches will further reduce the quality of the tree buds on the branches;

[0004] Present grafting technology all adopts prior art, but in fruit tree grafting process, because the bark contact surface between grafting branch and rootstock is little when grafting due to conventional grafting technology, grafted tree bud and rootstock grow together completely The grafting period is long, and it is prone to accidents, diseases or sudden changes in the weather, which will lead to grafting failure.
