Apple tree pruning management technology

Abstract

The invention discloses an apple tree pruning management technology. The apple tree pruning management technology comprises the steps of pruning, wherein pruning starts from apple trees of one year old, in the last ten days of November every year, lateral branches are pruned and reserved, one to two layers of lateral branches are reserved every year, three lateral branches are reserved for each layer of lateral branches, and the three lateral branches are distributed appropriately in a trifurcate in average; branch drawing, wherein in the last ten days of May the next year, subsidiary branches on the lateral branches are pruned, the lengths of the lateral branches are kept at not larger than 2 m, and the lengths of the fruit bearing branches on the lateral branches are not larger than 1 m; girdling in the middle ten days of June, wherein girdling comprises girdling of main branches and lateral branches, apple bark with the width of 1-3 cm is cut away through girdling, and the girdling mouths are covered by preservative film. Through the adoption of the apple tree pruning management technology, the ventilation and light transmittance of an orchard can be kept, the occurrence of the internal bark necrosis and the ring rot of apple trees can be effectively prevented and avoided, the yield is increased, and the quality of apples is improved.

Description

technical field [0001] The invention relates to fruit planting, in particular to an apple tree pruning management technique. Background technique [0002] The planting and cultivation time of apple tree is longer, and the level of apple tree is not obvious in the prior art, and ventilation and light transmission are poor. In the old apple orchard, due to the dense row and plant spacing of the fruit trees, the branches between the apple trees grow randomly. Due to the phototropism of the plants, the distance between the apple trees gradually decreases with the growth of the growth years. There are no walking paths in the apple orchard, which makes picking, pruning and fertilizing difficult. Trees occupy people's way, and people have no way to go in the apple orchard. The bottom branches of the tree do not bear fruit where they should bear fruit, only the top of the tree bears fruit, and the fruit in the inner hall is also inferior fruit. Most of the nutrients of the apple tr...

Problems solved by technology

[0002] The planting and cultivation time of apple trees is longer, and the level of apple trees is not obvious in the prior art, and the ventilation and light transmission are poor.

In the old apple orchard, due to the dense row and plant spacing of the fruit trees, the branches between the apple trees grow randomly. Due to the phototropism of the plants, the distance between the apple trees gradually decreases with the growth of the growth years. No walking paths in the apple orchard, making picking, pruning and fertilizing difficult

Trees occupy people's way, and people have no way to go in the apple orchard. The bottom branches of the tree do not bear fruit where they should bear fruit, only the top of the tree bears fruit, and the fruit in the inner hall is also inferior fruit. Most of the nutrients of the apple tree are consumed in the apple tree. On the branches and buds of the tree, small fruit appears on the upper layer of the apple tree, which reduces the quality and yield of apples in the entire apple orchard

Due to the random growth of apple tree branches, it is very easy to cause the distance between the branches to be too small. The closer to the center of the main trunk, the denser the branches are. 1. Poor ventilation, easy to produce canopy phenomenon, apple trees below 1 meter do not produce fruit or bear small fruit, the quantity and quality of fruit produced in the apple orchard decline year by year, make the orchard have poor ventilation and light transmission, and high humidity, causing apple trees to suffer from rough skin Increased chance of ringworm or ringworm
