Problems solved by technology

[0006] The purpose of the present invention is in order to overcome the problem in the prior art, provide a kind of tree form and pruning method thereof suitable for the transformation of densely planted jujube gardens in Xinjiang, the improved cylindrical tree shape suitable for the transformation of canopy closed jujube gardens, while maintaining the existing planting Under the condition of density, the tree shape is transformed in rows, which not only does not cut down the jujube trees, but also solves the problem of ventilation and light transmission in the jujube orchard, and is conducive to the mechanized management of the jujube orchard, saving labor and cost

Embodiment 1

[0018] A kind of tree shape suitable for the reconstruction of Xinjiang densely planted jujube garden of the present invention is characterized in that the jujube tree shape is designed as follows: the tree height is 1.8-2.5m, and the stem height is 40-45cm, along the central leading stem 18-20 secondary branches are distributed in a spiral pattern, which are divided into 3 layers. The first layer has 6-7 secondary branches, and the length is 7-9 nodes, 70-80° or natural branch angle; the second layer 7 ~8 secondary branches, 8~9 nodes in length, branch angle 80~90°; 4~5 secondary branches in the third layer, 5~6 nodes in length, branch angle 100~110°; layer spacing 25-35cm, the canopy is layered and cylindrical, the lower part is larger and the upper part is smaller.

Embodiment 2

[0020] The jujube orchards are densely planted with gray jujubes in Xinjiang, and the row spacing is 1.5-2m, and the jujube orchards are transformed;

[0021] S1. Plastic pruning in the first year: after the stems are cut off at a distance of 15cm from the surface, when the jujube heads germinate, the jujube heads with strong growth at the top are selected as the extension branches of the central leading stem. Keep 6-7 secondary branches, the bottom secondary branch is 40-45cm away from the ground, pick the heart when the secondary branch on the central leading trunk grows to 7-9 nodes, and keep the remaining 6-7 secondary branches to keep growing naturally , and use the methods of pulling branches, separating branches, and supporting branches to promote the branching angle of the secondary branches to 70-80°, forming the first layer of fruiting branch groups. If the tree vigor is weak in the first year, reduce the secondary branches retained. quantity;

Abstract

The invention discloses a tree shape suitable for the reconstruction of densely planted jujube gardens in Xinjiang and a pruning method thereof, belonging to the technical field of agriculture and horticulture. The design of the jujube tree type is: tree height 1.8-2.5m, trunk height 40-45cm, 18-20 secondary branches scattered in a spiral pattern along the central leading trunk, growing in 3 layers, with 6-7 secondary branches on the first layer. Secondary branches, 7-9 nodes in length, 70-80° or natural branch angle; 7-8 secondary branches in the second layer, 8-9 nodes in length, 80-90° in branch angle; 4 in the third layer ~5 secondary branches, 5~6 nodes reserved in length, branch angle 100~110°; layer spacing 25~35cm, tree crown is layered cylindrical, the lower part is larger and the upper part is smaller. The present invention solves the problem of poor ventilation and light transmission in super-high-density jujube gardens in Xinjiang when the crown shape is reduced; fully utilizes the space results, increases the number of fruit jujube strands, and solves the problem of jujube tree fruit parts moving outward; simplifies plastic surgery Pruning technology to reduce labor costs; provide suitable tree shape for the implementation of mechanized management in densely planted jujube gardens in Xinjiang.

Description

technical field [0001] The invention relates to the technical field of agriculture and horticulture, in particular to a tree shape suitable for the transformation of densely planted jujube gardens in Xinjiang and a pruning method thereof. Background technique [0002] As the fruit with the most ethnic characteristics, jujube has high edible value. Xinjiang jujube has bright color, thin skin, soft and sweet taste, and outstanding nutritional value. It is widely welcomed by jujube consumer groups, so it has very good market competitiveness and Development prospects, among them, the excellent quality of Xinjiang Junzao, compared with similar products, its fruit shape is large, thin skin, thick flesh, sweet and mellow taste, its vitamin C, protein, mineral content are higher than similar products, known as "China's first jujube", gray jujube is suitable for dense planting because of the positive correlation between early yield and branch volume, so Xinjiang Junzao and gray jujub...
