Water-saving dried area fruit tree irrigating device and using method thereof

Abstract

The invention relates to a water-saving dried area fruit tree irrigating device and a using method thereof. Water infiltration is the main reason for causing waste of the irrigation of the loess plateau, and inter-row grass growing has the defects of rich water competition and easy disease and insect parasitism. The action of covering films in fields for preventing water from infiltrating is not obvious, and plastic films can cause the environmental pollution. The water-saving dried area fruit tree irrigating device adopts the technical scheme that a water holding film is provided with breather holes, a separating zipper and drip pipe holes; a water seepage plate consists of drip pipe interfaces, an anti-clogging clamp plate and a water groove, and the water groove is provided with water guide holes; and the water seepage plate is arranged in the water holding film, and the drip pipe interfaces of the water seepage plate are connected with an irrigating pipe. When the water-saving dried area fruit tree irrigating device is used, the water holding film is embedded near a fruit tree; the zipper on the water holding film is zipped; the drip pipe interfaces of the water seepage plate are connected with the irrigating pipe; and then water is transported into the water holding film through a pipeline system. The water-saving dried area fruit tree irrigating device adopts a brand new water-saving irrigating design and can effectively prevent water transpiration and infiltration and achieve ideal water-saving irrigating effects when being applied to the loess plateau and desertification areas.

Description

technical field [0001] The invention relates to an irrigation device and a use method, in particular to a water-saving irrigation device and a use method for fruit trees in the arid area of ​​the Loess Plateau, and belongs to the technical field of agricultural engineering. Background technique [0002] The Loess Plateau in Northwest my country is mostly arid and semi-arid. On the one hand, the annual rainfall is small, and the soil evaporation is large; on the other hand, the soil layer is deep, and the irrigation water is easy to infiltrate and run off quickly. In addition, fruit tree production requires a lot of water, so water-saving irrigation and promotion of fruit tree production are the key technologies for fruit tree production in this area. Due to the deep soil layer of the Loess Plateau (average 50-80 meters), the soil is loose and the water infiltrates quickly. Water infiltration is the main reason for the waste of irrigation water in the Loess Plateau, but tra...

Problems solved by technology

Planting grass between rows (such as planting clover or alfalfa, etc.) can reduce field pollution and has a certain effect on preventing water evaporation and infiltration, but it also has the following disadvantages: first, there is competition between grass and fruit trees for fertilizer and water; second, grass is beneficial to The parasitism of diseases and in
