Method for repairing sick and disabled branches and trunks of fruit trees by utilizing germinal branches on branches and trunks

Abstract

The invention discloses a method for repairing sick and disabled branches and trunks of fruit trees by utilizing germinal branches on branches and trunks. The method comprises the steps that in the period between March and May, the fruit trees enter a tree sap flowing period, repairing is conducted; sick and disabled wounds of sick and disabled dry branches are cleaned; scab part bark layers are cut off by a cutter, fresh wounds are generated on the edges of the scab parts, the upper ends of the wound edges are cleaned, old barks are cut away, new barks can grow, and the wounds are smeared with a layer of mixed paint; the upper edges of the cleaned wounds are cut into incisions in a shape like the Chinese character of 'ding'; the characteristic that many resting buds can germinate at the lower ends of the fruit tree wounds is utilized to cut back coppice shoots at the lower ends of the fruit tree wounds, short piles are reserved to promote the germination of a plurality of coppice shoots, and a plurality of new branches on the short piles are guided to the upper ends of the damaged parts of fruit trees for successive cuttage grafting one by one; cuttages are subjected to the cottage grafting in the incisions in the shape like the Chinese character of 'ding', and the cuttages and trunks are closely bound through small nails or bandages. After the cuttages survive, the small nails are pulled out, and the plastic binding strips are unfastened. The method is simple in operations, cannot damage trees, and makes the fruit trees keep high yield.

Description

technical field [0001] The invention relates to a method for repairing diseased and residual branches of fruit trees, in particular to a method for repairing diseased and residual branches of fruit trees by using germinated branches on the branches. Background technique [0002] After the fruit tree enters adulthood and bears a lot of fruit, it is faced with the challenge of the natural environment, and it is inevitable that it will be harmed by diseases and insects. Affect yield and fruit quality. Almost all of these diseased and insect branches are disposed of during pruning during the dormant period. [0003] There is a common pruning practice in fruit tree producing areas. As long as the branches are found to be infested by diseases and insect pests, they can be cut off with an ax or a hand saw. Just imagine: it takes more than 10 years to cultivate a large backbone branch carefully, and this kind of backbone branch carries a lot of tasks of flowering and fruiting. Onc...

Problems solved by technology

[0006] In order to solve the technical problems in the prior art of cutting off the whole pest-damaged branches with an ax or sawing off the branches with a hand saw, resulting in reduced yield and low survival rate of single-branch grafting, the present invention provides a tree with an obvious effect of restoring tree vigor, A method for repairing diseased and residual branches of fruit trees by using branches on branches with higher survival rate of grafting
