Problems solved by technology

Since the water absorption process of plants is a continuous process, all irrigation methods in the past, whether watering, sprinkler irrigation, drip irrigation or infiltration irrigation, are intermittent irrigation. All intermittent irrigation methods are difficult to avoid water infiltration, evaporation and ground runoff. Low utilization rate, resulting in waste of water resources

Abstract

The invention discloses a water-saving irrigation device of improved saline-alkali soil. The water-saving irrigation device of the improved saline-alkali soil comprises a fresh water storage tank, a brine recovery tank, an irrigation salt drainage device and a brine recovery device, wherein the irrigation salt drainage device and the brine recovery device are buried underground, the irrigation salt drainage device is communicated with the fresh water storage tank, the brine recovery device is communicated with the brine recovery tank, the brine recovery tank is communicated with a brine desalination device, and the brine desalination device is communicated with the fresh water storage tank. The water-saving irrigation device of the improved saline-alkali soil is used for soil irrigation and improvement of saline-alkali soil regions, ingeniously combines moistube-irrigation, concealed pipe salt drainage and desalinization technologies, so fresh water is recycled, fresh water resources are saved, the problem of severe fresh water resource shortage of the saline-alkali soil regions is solved, the salt drainage effect is improved, and the saline-alkali soil irrigation and improvement effects are improved.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a water-saving irrigation system for improving saline-alkali land. Background technique [0002] With the continuous deepening of economic development, ecological problems have become increasingly prominent, especially the problem of land salinization in coastal areas has become more prominent. The saline-alkali land in coastal areas has the disadvantages of high salinity, low nutrient, large specific gravity and bulk density, low porosity and permeability coefficient, etc., which greatly restricts the ecological construction and agricultural production in coastal areas. Moreover, in saline-alkali land areas, fresh water resources are severely lacking and irrigation conditions are very limited, which are the main factors affecting plant growth. Therefore, in order to improve the ecological problems in saline-alkali land areas, it is fundamentally urgent to...
