Root division zone drip irrigation system for agricultural non-point source sewage purification and application thereof

Abstract

The invention discloses a root division zone drip irrigation system for agricultural non-point source sewage purification and application thereof. The root division zone drip irrigation system comprises a conical water pool, a coupling type micro-power water quality purifier and a claw type drip irrigation device, the conical water pool communicates with a rural non-point source sewage pipeline through a water inlet pipe, the coupling type micro-power water quality purifier is arranged in the conical water pool, and the claw type drip irrigation device communicates with a clear water pool in the center of the conical water pool. During use, rural non-point source sewage flows into the conical sewage pool through the water inlet pipe to be purified, purified water conducts root division zone irrigation on crops through the claw type drip irrigation device, the drip irrigation system is ingenious in structure, energy-saving and environment-friendly, accurate water-saving drip irrigationcan be achieved, and it is guaranteed that root systems of the crops are evenly distributed and grow; and the system has the characteristics of low operation energy consumption, simple operation, environmental protection, high efficiency, improvement of sanitary conditions of rural areas, and beautification of rural environment.

Description

technical field [0001] The invention relates to the technical field of agricultural drip irrigation, in particular to a root zone drip irrigation system for purification of agricultural non-point source sewage and an application thereof. Background technique [0002] With the rise of global temperature, water resources are increasingly scarce. The lack of water resources seriously restricts the development of agriculture in my country. Irrigation with point source sewage has become one of the environmental protection ways to alleviate the shortage of water resources; at present, the most commonly used irrigation methods are flood irrigation, furrow irrigation, drip irrigation and sprinkler irrigation, etc., and drip irrigation and sprinkler irrigation have obvious advantages in terms of high efficiency and water saving; From the perspective of water, drip irrigation can achieve precise irrigation, so that plants can absorb water and nutrients more fully; [0003] Agricultural...

AI Technical Summary

Problems solved by technology

[0004] There are many domestic studies on drip irrigation and sprinkler irrigation. Most of the existing drip irrigation technologies use reservoirs or groundwater as drip irrigation water sources, which wastes a lot of water resources. In terms of precision irrigation, most scholars' research mainly focuses on precise monitoring and quantitative fertilization. On the other hand, it is rare to use local non-point source sewage for precise irrigation of the root zone.
