Embodiment Construction

[0030] A technique for weeding and moisture conservation in apple orchards with low stock in the Loess Plateau area, the specific implementation scheme is as follows:

[0031] 1. Laying time and width requirements

[0032] (1) Cloth covering in late autumn and early winter

[0033] Immediately after applying the basal fertilizer in the orchard in autumn, it should be completed before the soil freezes. Orchards with relatively warm winters, shallow permafrost, and strong winds should be covered in late autumn and early winter.

[0034] (2) spring covering cloth

[0035] Immediately after the 5cm thick topsoil thaws, the sooner the better. Orchards with relatively cold winters, deep permafrost layers, and low winds are best covered in spring.

[0036] (3) Laying width

[0037] The laying width of the ground cloth should be 70-80% of the maximum branch spread of the tree crown, because the absorption roots of apple trees are mainly concentrated in this area, and the rainwate...

Abstract

The invention discloses a soil moisture preserving and weeding technique for a loess plateau area dwarf stock apple orchard. The method adopts a ground fabric which can stop sunlight directly radiating a ground surface; the ground fabric is solid in structure, which can stop weed penetrating the ground fabric, and then the ground fabric can inhibit the growth of the weeds and kill the weeds; the ground fabric is paved on the ground, the ground temperature remarkably increases in every spring, the root activity is improved, in particular to dwarf stock apple trees with shallow root systems ; the ground fabric is weaved, interweaved positions between warp and weft are provided with fine pores, and then the ground fabric has water permeability and air permeability; when rainfall is large in the orchard, excess water can form runoff, soil nutrients can be retained, and waterlogging damage to the roots can be avoided; the ground fabric has a certain tensile strength, and then can resist external force pulling and dragging in a general production condition; and after the ground is covered with the ground fabric, overwintering insects in soil can be stop coming up from the soil, and reproduction and infection of germs in the soil can be prevented and relieved.

Description

technical field [0001] The invention relates to a technology for moisture conservation and weeding in apple orchards, in particular to a technology for moisture conservation and weeding in apple orchards with low stock in the Loess Plateau region. Background technique [0002] Apple short stock intensive cultivation technology is an advanced apple production technology commonly used by developed countries in the world. Because of its high light efficiency, labor saving, early fruit, high yield, and fast renewal, it has been widely used in the loess plateau apple producing areas of my country in recent years. Rapid promotion and application. However, because the roots of dwarf apple rootstocks are generally distributed shallowly in the soil, their water requirements are higher than those of arborized rootstocks, and they are sensitive to water deficits. However, the annual rainfall in the Loess Plateau region is mostly concentrated between 430 and 560 mm, and presents a The u...
