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

Embodiment Construction

[0058] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0059] 1. About the pipeline (20)

[0060] 1) the structure of pipeline (20)

[0061] As shown in Figure 2, the structure of the pipeline (20) is: its cross section, from the inside to the outside, is followed by a water-permeable space (23), a skeleton (21) and an outer pipe (22);

[0062] The skeleton (21) is made of permeable or semi-permeable pipes;

[0063] The outer tube (22) is an outer tube of porous permeable material.

[0064] 2) Porous permeable material

[0065] Porous permeable materials can be selected from clay, geotextile, cotton, fine sand, cement mortar, ceramics (such as: tile pipe, clay brick, etc.), porous rubber, glass fine particles, etc. to form the outer tube (22) separately or according to a certain ratio An outer tube (22) is formed. The main usage methods are as follows:

[0066] * Clay material, the proportion is 10% to 99%, the ...

Abstract

The invention discloses a micro-flow irrigation method based on permeable materials, which relates to an irrigation method comprising the following steps. A. the pipelines(20)is adopted in the soil(10) for the layout of irrigation pipe network in which the terminal is communicated to a water source (40) through a valve (30). B. the required irrigation water quantity Q = Ev-E + P is calculated based on the rainfall P in the irrigation region, the soil evaporation E and the vegetation evaporation Ev. C. the valve (30) is manually controlled for the irrigation in accordance of the calculation result. The invention is simple in structure. The moisture evaporation in the soil surface and the ineffective infiltration irrigation loss are decreased. The irrigation water is saved with the uniform irrigation. The method is simple and flexible in the implementation, which is applicable to agriculture, horticulture, forestry irrigation fields related to the automatic water control.

Description

technical field [0001] The invention relates to an irrigation method, in particular to a micro-flow irrigation method based on permeable materials. Background technique [0002] Traditional irrigation technologies mainly include flood irrigation, watering, sprinkler irrigation, drip irrigation, micro-irrigation, infiltration irrigation and other irrigation technologies and automatic control technologies based on soil suction, soil change, biological morphology and other characteristics to synthesize automatic irrigation methods. The main problem is that these methods While irrigating vegetation, a water surface or a highly saturated soil layer is formed on the soil surface. Under natural conditions, the evaporation of water surface and soil water is relatively large, wasting a lot of water resources. Flood irrigation, watering, sprinkler irrigation, drip irrigation and other technologies will lead to infiltration of water, wasting a part of water resources; in addition, auto...
