Irrigation method and system

Abstract

The invention discloses a method and a system for irrigation. The method is characterized in that a depression terrain is treated and laid with an anti-seepage film, so as to form a reservoir; after rainwater is collected into the reservoir, the rainwater is led into a water storage tank, filtered and then connected to a moistening-irrigating water feeder through a pipeline; the moistening-irrigating water feeder is put below plant roots; and water is conveyed to the plant roots through a moistening guide pipe of the moistening-irrigating water feeder. The invention provides a novel efficient water-saving damp irrigation technique saving more water, which has the advantages that the technique can automatically regulate water with atmospheric precipitations in damp areas so as to continuously guarantee the water needed by plant growth. The technique of the invention can guarantee the survival and normal growth of plants (crops) to the utmost extent, and can grow the plants (crops) with high economic value or good ecological benefit, such as watermelon, cucumber and other plants of a fibrous root system, as well as fruit trees, forest trees and other plants of a taproot system, so as to achieve the aims of restoring ecosystem and increasing the income of farmers.

Description

technical field [0001] The invention relates to an irrigation technology, in particular to an irrigation method and system suitable for effective water collection and irrigation in karst rocky desertification areas in southern my country. Background technique [0002] Drought is the main limiting factor of the ecological environment in the karst rocky desertification area in southern my country, and it is also the limiting factor that leads to the fragility of the ecological environment system and the reduction of environmental carrying capacity. It seriously restricts the development of agricultural production and rural economy. In karst rocky desertification areas, the limestone is exposed to a high degree, the soil layer is thin, the water retention capacity of the lime soil structure is poor, the soil heats up quickly, and the evaporation is strong. The traditional irrigation technology consumes a lot of water. Even if the drip irrigation system is used, the land seepage ...

Problems solved by technology

In karst rocky desertification areas, the limestone is exposed to a high degree, the soil layer is thin, the water retention capacity of the lime soil structure is poor, the soil heats up quickly, and the evaporation is strong. The traditional irrigation technology consumes a lot of water. Even if the drip irrigation system is used, the land seepage in the karst area is serious. , the water saving effect is not ideal
