Problems solved by technology

[0003] Since the greatest potential for my country's agricultural water saving lies in the field, at present, surface irrigation such as border irrigation, furrow irrigation, flood irrigation and other irrigation methods are usually used. It is easy to form compaction, and the water content of the surface soil is too high, which makes the soil permeability poor and the crop root system has difficulty breathing
And with the development of modern large-scale agricultural operations, mechanized crop transplanting is bound to become a trend. However, conventional ground irrigation cannot meet the needs of mechanized transplanting crops due to poor mobility, slow water flow, and long irrigation duration. requirements

Abstract

The invention discloses an irrigation system; the irrigation system comprises a water conveying hose and a water spraying device, wherein the water conveying hose can move in any direction; and the water spraying device is connected with the water conveying hose; the water spraying device comprises a first branch pipe, a micro-spraying belt group and a bypass valve group, wherein the first branch pipe is connected with the water conveying hose; the micro-spraying belt group comprises a preset number of micro-spraying belts; the micro-spraying belts are respectively connected with the first branch pipe; the bypass valve group comprises bypass valves corresponding to the micro-spraying belts one to one; one ends of the bypass valves are mounted in the first branch pipe; and the other ends of the bypass valves are connected with the corresponding micro-spraying belts. According to the invention, through the adoption of the water conveying hose, the irrigation system is convenient to move; through the adoption of the micro-spraying belt mode, spraying irrigation is rapidly and uniformly carried out to satisfy requirements on timely supplemental irrigation of mechanically transplanted crops and save irrigation water; and furthermore, a situation that crop root systems are hard to breathe due to poor soil permeability caused by overhigh water content of a surface soil is avoided, so that the production efficiency of the crops is increased.

Description

technical field [0001] The invention relates to the technical field of farmland water-saving irrigation, and more specifically relates to an irrigation and fertilization system. Background technique [0002] my country is a country with severe drought and severe water shortage. Fresh water resources only account for 6% of the world's total. The dwindling water resources make people realize the importance of water conservation. Among them, agricultural water accounts for as much as 80% of my country's total water volume, so how to save agricultural water has become the focus of my country's water-saving work. [0003] Since the greatest potential for my country's agricultural water saving lies in the field, at present, surface irrigation such as border irrigation, furrow irrigation, flood irrigation and other irrigation methods are usually used. It is easy to form compaction, and the water content of the surface soil is too high, which makes the soil permeability poor, and th...
