Tree irrigation method and system

Abstract

Embodiments of the present application provide a tree irrigation method and system. The method comprises: on a ground circumference with a preset radius by using the trunk of a tree as the center of a circle , punching at least one pipe holding hole in a direction perpendicular to the ground, wherein the length of the pipe holding hole is matched with the length of an irrigation pipe; inserting an irrigation pipe in each pipe holding hole, wherein the irrigation pipe is a pipe which is provided with a plug at the lower end and is fully distributed with micropores on the pipe wall; connecting the upper end of the irrigation pipe to a first connection pipe three a tee, so that an annular water pipe is formed above the irrigation pipe and is connected to a water source; and after backfilling the pipe holding hole with the irrigation pipe by using soil, opening the water source and supplying water to the water pipe, so that columnar wet body using the irrigation pipe as an axial center is formed, and finally an annular irrigation area that is centered on a root of the tree is formed around the root of each tree. Thust, the trees irrigation method and system can solve the disadvantages existing in a scheme of applying an existing water-saving irrigation technology to deep rooting trees irrigation, and on the basis of water saving, the entire root system of trees can be uniformly and tridimensionally irrigated.

Description

technical field [0001] The embodiments of the present application relate to the field of irrigation, in particular to a tree irrigation method and system. Background technique [0002] With the increasingly serious shortage of water resources in our country, water-saving irrigation technology has become an important technology for the development of agriculture and forestry. In the prior art, more commonly used water-saving irrigation techniques include drip irrigation technology, etc., so-called drip irrigation (drip irrigation), refers to the use of plastic pipes to send water to the roots of crops through the dripper on the capillary with a diameter of about 10 mm for local irrigation. For irrigation, when the drip irrigation technology is used for ground irrigation, the amount of water is limited each time, the wet body formed is small, and the wet depth of water generally does not exceed 0.5 meters. For agricultural production, such shallow irrigation (wetting depth o...

AI Technical Summary

Problems solved by technology

For agricultural production, such shallow irrigation (wetting depth of water) is basically sufficient, but for trees with deep root systems such as fruit trees (the root depth of general fruit trees is 2 meters to 3 meters, and some are even as deep as more than ten meters). In other words, if this kind of shallow irrigation is carried out for a long time, the root system of trees will not extend to the deep layer, but most of them will be distributed in the shallow layer of the surface. This kind of shallow root system is very unfavorable for the wind resistance, frost resistance, nutrition and water absorption of trees. , in severe cases, only the roots under the dripper are very developed, while the roots far away from the dripper become weak or even shrink because they cannot be properly irrigated. Technical barriers to the application of similar water-saving irrigation techniques in deep-rooted tree irrigation
