Method for restoring ill and injured trunks and branches of crowns of fruit trees

Abstract

The invention discloses a method for restoring ill and injured trunks and branches of the crowns of two fruit trees. According to the method, restore of the ill and injured trunks and branches of onefruit tree is achieve by utilizing the treetops of the other fruit tree next to the fruit tree. The method includes the steps that the middle of April is selected as the time for restoring the injuredbranches and trunks of the fruit trees, and restore is completed by means of a grafting method under the condition that the twigs stay in a germination period and buds on the twigs do not germinate;the growth tendency and state of the twigs on the branches and trunks of the two fruit trees are observed, and the grafting method is determined according to the growth tendency and state of the twigson the branches and trunks of the two fruit trees; shoots below grafting incisions are controlled to germinate, and the redundant shoots are removed in time; binding bands on the grafting incisions are untied one and half months later; after the branches and trunks completely survive, one strong branch of each tree is reserved, and the other branch of each tree is cut off from the upper portion of a connection port. The defects that instead of carrying out restore, ill twigs are directly cut off in the prior art and therefore damage and yield reduction are caused to the fruit frees are overcome. Through effective restore of damaged parts, the fruit trees recover to a luxuriant state, and production of fruits is continued. The method is simple in technical operation and easy to learn.

Description

technical field [0001] The invention relates to a method for repairing fruit tree trunk branches, in particular to a method for repairing crown diseases and residual trunk branches of fruit trees. Background technique [0002] After fruit trees enter adult fruit, they are faced with the challenges of the natural environment. The trunk or backbone branches will inevitably suffer from diseases and insects, which not only affect the tree body, but also affect the yield and fruit quality. During the pruning season during the dormant period, almost all the branches that have been damaged by diseases and insect pests have been disposed of. [0003] For the branches of fruit trees affected by diseases and insect pests, the common pruning method in fruit tree producing areas is: as long as the branches are found to be damaged by diseases and insect pests, either use an ax to cut off the whole branches, or use a hand saw to saw off the branches. Just think about it: It takes about 1...

Problems solved by technology

Just think about it: It takes about 10 years or more to cultivate a general backbone branch, and this kind of backbone branch bears a lot of tasks of flowering and fruiting. Once this big tree removes the backbone branch, it can remove 1 / 5-1 / 3 Left and right output, but also affect the further increase in output after many years! It is almost impossible to re-cultivate the original branches, and this traditional method of dealing with sick branches is becoming less and less acceptable
