Device and method for collecting water in orchard

Abstract

The invention discloses a device and a method for collecting water in an orchard. The method comprises the following steps: finishing the ground; mounting movable supports; covering a black water-collecting plastic film over 0.06mm; punching; fixing a water guide pipe in a ground hole in the bottom of a water collecting pit. The device comprises iron wires, the water-collecting film (having the water guide pipe), and the movable supports. The film is fixed by threading No. 12 iron wires through a film edge fixing pipe; a water guide hole is formed in the film; the water guide pipe is adhered to a corresponding position of the water guide hole; the movable brackets are arranged at both ends of the film; two support arms are connected with the iron wires, and the two iron wires are parallel. According to the device and the method disclosed by the invention, a mode in which rainwater is uniformly received by the soil surface is changed into a time-space distribution mode in which rainwater is received by deep soil at multiple points in a concentrating manner, such that rainwater directly reaches to a root system distribution layer of a fruit tree to strength the rainwater infiltration depth, reduce the evaporation loss of water in soil and prolong the retention time of rainwater in soil, more water is provided for growth of fruit trees in case of not increasing water supply, and therefore the yield and the quality of fruits are improved.

Description

technical field [0001] The invention belongs to the technical field of orchard management, in particular to an orchard water collection device and method. Background technique [0002] The Loess Plateau is one of the two eugenic areas for apples in my country. The apple industry has become a pillar industry in the Loess Plateau. The traditional soil management mode has led to the degradation of soil moisture in orchards, and the decline in fruit yield and quality. The research results show that the water content of the 3-9m soil layer of the apple field section in the Loess Plateau for more than 14 years is basically close to the field withering humidity of the local soil, and the strong transpiration and evaporation of apple trees consume the annual rainfall infiltration, and Continuously use the soil to effectively store water, promote the further drying of the deep soil, and form a soil biologically usable desiccation layer. The evolution trend of the desiccation layer i...

Problems solved by technology

To sum up, except for infiltration irrigation technology, all technologies are based on the fact that the surface is the receiving surface for rainfall, and the rainwater is received by the surface soil, that is, the rainfall is firstly received by the surface soil, and the soil moisture is controlled according to the stage of evaporation, atmospheric control, and soil water conduction. The rate control stage and the diffusion control stage are carried out. The soil water loss is closely related to the rainfall frequency and rainfall, which cannot effectively reduce the water evaporation loss. Especially for the rainfall of <15mm, when the surface soil is relatively dry, it cannot...
