Embodiment Construction

[0012] In order to describe in detail the technical content, achieved objectives and effects of the present invention, the following will be described in detail in combination with the embodiments.

[0013] The specific method is:

[0014] 1) Colonization: When planting jujube trees, the plant spacing is 1-1.5 meters, and the row spacing is 2.2-3.5 meters;

[0015] 2) Trunking: Before the jujube tree germinates in spring in the first year of planting, select a strong main bud A 15-30cm above the ground, cut off the trunk above the strong main bud A, and stimulate it to germinate a strong upright growth Zaotou B.

[0016] 3) Cultivate and extend the skeleton branch system: in the summer of the first year, when 6-7 secondary branches grow from the new jujube head B, pick the top-growing main buds of the new jujube head B to stimulate the acceleration of the secondary branches Extend the growth, so that you can increase the extended growth by 1-2 times without topping, and incr...

Abstract

The invention relates to a shaping and pruning method suitable for jujube dense planting. By changing the planting form, the row spacing is adjusted to 1-1.5 meters between rows and 2.2-3.5 meters between rows. This method does not use a plurality of jujube heads as the main branch system for expanding the crown, but uses the whorled secondary branches on the middle upright jujube head as the main branch system for forming the crown, thereby forming a "column" crown. The method makes the layout of the tree structure reasonable, realizes forming in two years, enters the fruiting period in three years, and can achieve high-yield, stable yield, high-quality and high-efficiency cultivation effects. It solves the shortcomings of the conventional jujube cultivation technology, such as slow gardening, late fruiting, easy canopy closure, unfavorable mechanized operation, time-consuming and labor-intensive management, and lack of effectiveness.

Description

technical field [0001] The invention relates to a pruning method for fruit trees, in particular to a method suitable for shaping and pruning jujube orchards with dense planting. Background technique [0002] Fruit tree shaping and pruning is an important part of fruit tree cultivation, among which: jujube tree is a unique national fruit tree in my country, which has its unique branch and bud characteristics. During the cultivation process, according to its cultivation form, choose appropriate shaping and pruning The method is the key to realize high-quality, high-yield and high-efficiency cultivation of jujube trees. [0003] In conventional jujube cultivation techniques, the general plant-to-row spacing forms are: plant-to-plant spacing 2-3m, row spacing 4-5m, 44-84 plants / mu, and the selected tree shape is generally: natural round head shape, happy shape, small crown Evacuation layered shape, etc. Its canopy is formed by many new jujube heads developing into main branch...
