Embodiment 1

[0024] A kind of " U " shape tree shaping method that the present invention proposes improves jujube illumination and ventilation effect, comprises the following steps:

[0025] S1, dig a hole: the main root of jujube seedling is pruned, and then the ground is leveled, with reference to 1.8 times of jujube seedling root size digging is wide, with reference to 1.2 times of jujube seedling root depth digging is deep, and the row spacing between pit and pit is 2m, The distance between plants is 5m to ensure that the roots of jujube seedlings can fully stretch in the pit;

[0026] S2, planting: according to mass ratio 12:3:1, the subsoil of digging pit, organic fertilizer and root-absorbing powder are mixed and fill in pit bottom layer, and the thickness of filling is 4cm, chooses in mid-October, and jujube seedling is planted in pit. In the center, add small wooden piles to fix after filling the soil;

[0027] S3, anti-cold: Cultivate 20cm high soil platforms at the base of juju...

Embodiment 2

[0031] A kind of " U " shape tree shaping method that the present invention proposes improves jujube illumination and ventilation effect, comprises the following steps:

[0032] S1, dig a hole: pruning the main root of jujube seedlings, then leveling the land, digging pit width with reference to 2.1 times of jujube seedling root size, digging pit depth with reference to 1.4 times of jujube seedling root depth, the row spacing between pits and pits is 3m, The distance between plants is 6.5m to ensure that the roots of jujube seedlings can fully stretch in the pit;

[0033] S2, Planting: According to the mass ratio of 15:4:1, mix the subsoil, organic fertilizer and rooting powder of the excavated pit and fill it into the bottom of the pit. In the center, add small wooden piles to fix after filling the soil;

[0034] S3, anti-cold: Cultivate a 25cm high soil platform at the base of jujube seedlings to fix it, set up the tree tray before freezing on the soil, water the jujube tre...

Embodiment 3

[0038] A kind of " U " shape tree shaping method that the present invention proposes improves jujube illumination and ventilation effect, comprises the following steps:

[0039] S1, dig a hole: pruning the main root of the jujube seedling, then leveling the land, digging the pit width with reference to 2.4 times of the jujube seedling root size, digging the pit deeply with reference to 1.5 times of the jujube seedling root depth, the row spacing between the pit and the pit is 4m, The distance between plants is 8m to ensure that the roots of jujube seedlings can fully stretch in the pit;

[0040] S2. Planting: According to the mass ratio of 18:5:1, mix the subsoil, organic fertilizer and rooting powder of the pit and fill it into the bottom of the pit. In the center, add small wooden piles to fix after filling the soil;

[0041] S3, cold protection: cultivate a 30cm high soil platform at the base of jujube seedlings to fix it, set up the tree tray before freezing on the soil, ...

Abstract

The invention belongs to the technical field of fruit tree body shaping, particularly relates to a U-shaped tree body shaping method for improving illumination and ventilation effects of jujube trees, and solves the problems that in the prior art, the growth of the jujube trees is mostly unbalanced in tree body structure, the management work difficulty of insecticide spraying, picking and the like is large, and the jujubes are not good enough in yield and quality and common in taste. The U-shaped tree body shaping method for improving illumination and ventilation effects of jujube trees comprises the following steps: digging pits according to the sizes and depths of roots of jujube seedlings; after the pits are stuffed with soil and fertilizer, planting the jujube seedlings in the centers of the pits; taking cold-proof measures on the jujube trees; selecting two strong branches which are full in bud leaves and opposite in pairs along the row spacing direction for fixing and shaping; and cutting back the vigorous buds on the main branches, and thinning or flattening competitive branches of extension branches of the main branches. By designing a U-shaped jujube tree body, on one hand, illumination and ventilation required by the jujube trees in the growing period are greatly guaranteed, and on the other hand, mechanical operations including pesticide spraying, harvesting and the like can be greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of fruit tree shaping, in particular to a U-shaped tree shaping method for improving the lighting and ventilation effects of jujube trees. Background technique [0002] Jujube deciduous small tree, sparse shrub, up to more than 10 meters; bark brown or taupe; long branches, short branches and budless branchlets (that is, new branches) are smoother than long branches, purplish red or gray brown, zigzagging , with 2 stipules, the long spines can reach 3 cm, thick and straight, the short spines are curved, 4-6 mm long; the short branches are short and thick, rectangular, emanating from the old branches; the branchlets of the current year are green, drooping, single Young or in clusters of 2-7 on short branches. Jujube trees are temperature-loving trees, relatively drought-tolerant, and also relatively waterlogging-tolerant, and suitable watering is enough. However, the growth of jujube trees, especially when j...
