Coated drip irrigation pipe capable of applying common compound fertilizer

Abstract

The invention relates to a coated drip irrigation pipe capable of applying a common compound fertilizer, and belongs to the technical field of agricultural irrigation. The coated drip irrigation pipe comprises a main pipe and a coated pipe, wherein one side of the coated pipe is split along the axial direction and then coated on the main pipe by virtue of self elasticity; a drainage hole is fabricated at the position of the main pipe coated by coated pipe; the aperture of the drainage hole is 1-1.5mm; the length of the coated pipe is 5-15cm. The coated drip irrigation pipe capable of applying the common compound fertilizer is coated on the main pipe by virtue of the elasticity of the coated pipe, so that a gap is generated between the inner wall of the coated pipe and the outer wall of the main pipe to slowly drip out the water of the drainage hole; the drip irrigation effect is good; the position of the drainage hole can be flexibly changed according to the position of the root; the domestic common compound fertilizer with large particles can be fertilized through the main pipe; the main pipe is not easily blocked. Thus, the problems of short service life, poor drip irrigation effect and high production cost of the existing drip irrigation pipe, and the problem that the common compound fertilizer cannot be applied due to the fact that the position of the drainage hole is a fixed position are solved.

Description

Technical field [0001] The invention relates to a coated drip irrigation pipe capable of applying common compound fertilizer, and belongs to the technical field of agricultural drip irrigation. Background technique [0002] In the process of planting and managing economic forests such as grapes and fruit trees, the roots must be watered. Due to the current lack of water resources, people have changed from flood irrigation and sprinkler irrigation to drip irrigation, which can save a lot of water resources. The dropper used in current drip irrigation generally has four structures. The first is a single-wing labyrinth drip irrigation tape. Although the drip irrigation tape is easy to manufacture and low in cost, the drip irrigation is very uneven, the drip irrigation effect is poor, and the service life is short. Years have been eliminated. The second type is the built-in cylindrical drip irrigation pipe. The drip irrigation pipe has a uniform water supply, a better drip irrigatio...

AI Technical Summary

Problems solved by technology

The droppers used in existing drip irrigation generally have four structures. The first is a single-wing labyrinth drip irrigation belt. Although the drip irrigation belt is easy to manufacture and low in cost, the drip irrigation is very uneven, the drip irrigation effect is poor, and the service life is short. year has been eliminated

The second is the inner garden column drip irrigation pipe. This drip irrigation pipe has uniform water supply, better drip irrigation effect and longer service life, but the dripper is easy to cause blockage. Even if a filter is installed, it can only be used for two to three times. year will cause drip irrigation to be scrapped

The third is the external dripper type drip irrigation pipe, which has a good drip irrigation effect, but its disadvantage is that it is easy to block

The fourth type is the inlaid patch type drip irrigation belt. This drip irrigation belt is the technology introduced from Israel. The drip irrigation is uniform, the effect is good, and the price is cheap. It is widely used at present, but it can only drip imported water-soluble compound fertilizers. Fertilization is expensive. The price of fertilization per mu per year is as high as more than 1,000 yuan

Among the above four structures, the second, third, and fourth structures all have common compound fertilizers that cannot be drip-applied, and compound fertilizers imported from abroad must be drip-applied, and ordinary compound fertilizers will be blocked when drip-applied, causing drip irrigation pipes or drip irrigation belts to be scrapped and The position of the outlet hole is fixed and cannot be flexibly changed with the position of the tree root.
