Tree shape and pruning method of pear tree with slow tree potential and fruit dropping prevention

Abstract

The invention discloses a tree shape and a pruning method of a pear tree with slow tree potential and fruit dropping prevention, and the pear tree with slow tree potential and fruit dropping prevention is 2.4-2.6m high with 50-60cm pure height, and four main branches are reserved in two layers on the trunk; the upper main branch is one, at the top of the trunk, the opening angle is 70-80 degrees,and 1-2 lateral branches are reserved on the upper main branch; the distance between the three main branches of the lower layer and the main branch of the upper layer is 60-80cm and is staggered withthe main branch of the upper layer, the opening angle of the lower main branch is 60-70 degrees, and three lateral branches are reserved on each lower main branch; each lateral branch is provided witha fruiting branch or a fruiting branch group, and the fruiting branch with a diameter larger than 1cm is fixed on a wire mesh with a height of 2.0-2.2m from the ground height; the tree shape can resist wind damage, greatly reduce fruit dropping and ensure high yield and stable yield; secondly, compared with the conventional pear tree, the tree with slow tree potential and fruit dropping has better ventilation and light transmission conditions, and good fruit quality; thirdly, the tree potential can be slowed down; fourthly, the tree has high fixed truck and high frame, and is suitable for mechanized operation; fifthly, the trimming method is simple, the operation is good, and the method is easy to master.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting and management, in particular to a tree shape and pruning method for slowing tree vigor and preventing fruit drop. Background technique [0002] Existing pear tree shape generally is to grow secondary branch on main branch, and grow fruiting branch on secondary branch. Due to the disordered arrangement of branches, it is impossible to make each fruiting branch evenly irradiated by sunlight, which seriously affects the yield and fruit quality of fruit trees; secondly, the branches and leaves are weak in wind damage resistance, and it is very easy to cause fruit drop due to wind damage, which affects yield Again, the space under the tree is less, seriously affects the operation under the tree of relevant mechanical equipment, causes labor intensity big, labor efficiency is not high. Contents of the invention [0003] In order to solve the above problems, the present invention provides...

Problems solved by technology

Due to the disordered arrangement of branches, it is impossible to make each fruiting branch evenly irradiated by sunlight, which seriously affects the yield and fruit quality of fruit trees; secondly, the branches and leaves are weak in wind damage resistance, and it is very easy to cause fruit drop due to wind damage, which affects yield ; Again, the space under the tree is small, which seriously affects the operation under the tree of related mechanical equipment, resulting in high labor intensity and low labor efficiency
