Technique and method for cultivation and management of trimmed apple tree with reverse drooping branch

Abstract

The invention discloses a technique and a method for cultivation and management of a trimmed apple tree with reverse drooping branches, belonging to the fruit tree cultivation technique, in particular to a technique and a method suitable for cultivation and management of a trimmed apple tree with reverse drooping branches. The technique adopts a method of improving soil conditions without deep plowing, the amount of farmyard manure per mu is more than 6000kg, fish protein is sprayed to increase nutrients and organic fertilizers and trace elements are also applied. Generally, 100kg of fruits need 8-10kg of fertilizers. The types and quantities of the trace elements are determined according to measurement results, and noconboron and noconcalcium can be used. The fertilizers are applied in three stages, e.g. after bagging fruits of trees, during the fruit enlargement period and in September and are spread over the field, the trees are irrigated after application of the fertilizers, the branches are drawn to promote flower formation, the fruits are thinned and bagged, and biological agents and high-efficiency and low-toxicity pesticides are used for pest and disease control, thereby reducing the fruit pollution caused by use of pesticides. The method transforms the vegetative growth of apple trees into the reproductive growth, thereby improving the yield and quality of the fruits. Moreover, the method facilitates the formation of the shape of the apple trees with reverse drooping branches, promotes the high and stable yield of the fruits of the apple trees, improves the quality of the fruits, and overcomes the defect of alternate yields of the trees.

Description

technical field [0001] The invention belongs to the fruit tree cultivation technology, in particular to a technology and method suitable for the cultivation and management of apple trees by shaping the inverted branches of apple trees. Background technique [0002] my country's current fruit tree cultivation management mainly refers to the management of soil, fertilizer, water, and pest control. Generally, after the fruit trees lose their leaves in autumn, the orchard is deeply plowed, combined with deep-buried organic fertilizers, watered with winter water, and before the fruit trees germinate in spring, they are sprayed to kill the fruit trees. Insecticides, and water permeable to promote fruit trees to germinate, and then water, fertilize, and spray insecticides and fungicides in time as the fruit grows, often due to carelessness in the amount of fertilization and watering, resulting in vegetative growth and reproductive growth of fruit trees The unbalance of apple trees, e...

[0002] my country's current fruit tree cultivation management mainly refers to the management of soil, fertilizer, water, and pest control.

Insecticides, and water permeable to promote fruit trees to germinate, and then water, fertilize, and spray insecticides and fungicides in time as the fruit grows, often due to carelessness in the amount of fertilization and watering, resulting in vegetative growth and reproductive growth of fruit trees The unbalance of apple trees, especially the inverted drooping apple tree, once the imbalance of vegetative growth and reproductive growth is formed, it will cause excessive branching, closed canopy, and a large number of comb branches will be formed during winter pruning, resulting in waste of tree nutrition. , delay the formation of fruit tree shape, affect the fruit yield of fruit trees, and reduce the quality of fruit, resulting in the size of the fruit tree yield
