Problems solved by technology

[0005] Due to the lack of a simplified tree shape suitable for high-density cultivation of jujube trees, many jujube orchards experience canopy closure in about 3-5 years after fruiting, and the yield and quality decline rapidly.

Embodiment Construction

[0022]For the jujube trees that were built live in the garden, in the winter of the year after grafting, the central trunk was cut short at a distance of 60 cm from the ground. 2 short cuts. In the second year, when pruning in summer, select the new jujube heads from the uppermost secondary branches of the center trunk as the extension branches of the center trunk, and choose one of the new jujube heads from the next three secondary branches with a large opening angle and strong The new jujube heads of the new jujube heads are reserved as the extension branches of the first layer of fruiting branches, and all other new jujube heads that are not used as extension branches on the tree are removed, and the opening angle of the extension branches of the fruiting branch groups is adjusted to 90 degrees; 100 centimeters from the ground, cut short the extension branches of the central trunk, keep 1 short cut for the uppermost secondary branch, leave 2 short cuts for the next 3 second...

Abstract

Disclosed is a simplified tree form reforming method suitable for a high-density jujube orchard. Since the grafting year of direct seeding and orchard building or the planting year, by about five-year continuous reforming, a jujube head form tree is formed with tree height of 2.5-3.5 meters, branch spreading of 1-1.5 meters, central trunk bending upwards, and 10-20 bending horizontally stretching fruiting branch groups directly inserted on the central trunk. The reforming method is suitable for wide-row dense-planting high-density jujube orchards (tree row space is 0.5-1.5m*3-4.5m), and simple in reforming. The reformed trees are slim and high, the branches are well-spaced without crossing, large row space can be guaranteed under high-density conditions, good ventilation and light permeability are achieved, high and stable yield and good quality are guaranteed, mechanical operation is facilitated, manpower for cutting is saved by more than 80%, and the problems that the high-density jujube orchard is prone to closing, complex to manage and the like are solved.

Description

technical field [0001] The invention relates to a simplified tree shaping method suitable for high-density jujube orchards. Background technique [0002] Due to its unique advantages such as early flowering and fruiting, early high yield, high yield per unit area, good quality, convenient management, mechanization, faster renewal of varieties and recovery of yield, and economical use of land, dwarf dense cultivation has become the main development of fruit trees at home and abroad. trend. Since the reform and opening up, the low-density cultivation of large fruit trees such as apples and pears has developed rapidly, and has achieved very significant economic and social benefits in production. On the other hand, along with the sharp rise of labor costs in recent years, it is imperative to simplify cultivation to save labor and labor. [0003] jujube( Ziziphus jujuba Mill.) is an important fruit tree native to my country. Due to the characteristics of strong stress resist...
