Irrigation system based on water transport quantity automatic control material

Abstract

The invention discloses an irrigation system based on delivery automatic-control material, which relates to an irrigation system. The invention adopts a pump (20) to lay out irrigation pipe network in the soil (10); the terminal of the irrigation pipe network is communicated with water source (40) by a valve (30). The structure of the pipe (20) is that the cross section from the inside to outside is provided with an inner pipe (23), a frame (21) and an outer pipe (22) in sequence; the frame (21) is composed of permeable or semipermeable pipe; the outer pipe (22) is an outer delivery automatic-control pipe; the inner pipe (23) is normal hollow pipe or a conveyance pipe made of strongly permeable material. The invention, water transmission property of which can change according to the water content of plant soil, so as to save irrigation water, provide more proper environment for plant growth and is applicable to irrigation fields which relates to elivery automatic-control, such as agriculture, gardens, forestry practice, etc.

Description

technical field [0001] The invention relates to an irrigation system, in particular to an irrigation system for automatically controlling materials based on water delivery. Background technique [0002] The traditional irrigation methods mainly include: flood irrigation, watering, sprinkler irrigation, drip irrigation, micro-irrigation, seepage irrigation, negative pressure irrigation and other methods and automatic irrigation methods based on automatic control technology based on soil suction, soil change, biological morphology and other characteristics. The main problem is that these methods form a water surface or a highly saturated soil layer on the soil surface when irrigating vegetation. Under natural conditions, the evaporation of water surface and soil moisture is relatively large, which wastes a large amount of water resources; The cost of automatic control technology based on soil suction, vegetation shape, and growth status is relatively high, and the water-saving...

AI Technical Summary

Problems solved by technology

[0004] 1. While irrigating vegetation, the traditional irrigation method forms a water surface or a highly saturated soil layer on the soil surface. Under natural conditions, the water surface and highly saturated soil have a large amount of water evaporation, wasting a lot of water resources

[0005] 2. The traditional irrigation method is easy to over-irrigate, causing excess water to infiltrate into the area beyond the influence of vegetation, and the vegetation cannot be used, wasting water resources

[0006] 3. Processes such as flood irrigation, sprinkler irrigation, drip irrigation, and infiltration irrigation cannot control the amount of irrigation water according to the growth status of vegetation, and human intervention or control systems are required to realize irrigation operations

[0007] 4. Using an irrigation system based on electronic control and automatic control of soil and vegetation information, the water saving effect is better, but the cost is high
