Grafting method capable of rapidly fixing incomplete crown of fruit tree

Abstract

The invention belongs to the technical field of plant biology, in particular to a grafting method capable of rapidly fixing an incomplete crown of a fruit tree. A fruit tree where a mesome is sewed off is used as a tree stock and a robust water sprout or a vertical growing branch is selected near a damaged mesome, softened and pulled to a processing face of the tree stock. A to-be-processed position is selected on the branch and used as a bending point, and then the branch is bent over. A grafting cutter is used for cutting along the length direction of the branch to form a cutting face which is 4cm to 7cm long. The cutting thickness is one fourth to one third of the thickness of the branch at the bending point and a cion is formed. Affinity between the cion and the tree stock is strong and healing an injury is fast and easy so that the cion grows fast and robustly. The selected cion is often a water sprout useless for production in grafting operation so that a bearing branch of an entire fruit tree is not influenced and the yield of the year and the yield of the next year are not affected.

Description

technical field [0001] The invention belongs to the field of plant biotechnology, and in particular relates to a grafting method for quickly repairing the incomplete crown of fruit trees. Background technique [0002] Fruit trees are high-yielding, multi-functional economic crops. The fruit market has a large demand space and is a model of high-efficiency agriculture. It plays a huge role in promoting the adjustment of agricultural structure, changing the mode of agricultural economic growth, building modern agriculture, and promoting farmers' income and agricultural efficiency. Since the 1980s, my country's fruit tree industry has developed at a high speed, which has made important contributions to the development of the national economy and also played an important role in improving the quality of life of the people. The fruit is rich in nutrition and medical value, and contains five major nutrients such as sugar, protein, fat, minerals and vitamins needed by the human bo...

Problems solved by technology

However, the problem of transforming into a happy shape is that the three-dimensional effect is not realized, so that the yield per unit land area is not high, and a large number of excessively long branches occur in the tree body every year, resulting in waste of nutrients and a decline in fruit quality; hard branch grafting restores the trunk type and there is a time for recultivation Long (at least 3 to 5 years), there are many excessively long branches in the early stage, resulting in waste of nutrients and decline in fruit quality
