Abstract

The invention discloses a saline-alkali land greenhouse system in the Hetao irrigation district and belongs to the technical field of saline-alkali land improvement. The system comprises a motor-pumped well and a submersible pump disposed in the motor-pumped well, a water collection tank disposed on the ground surface, a greenhouse frame body, and a transparent greenhouse ceiling disposed on the greenhouse frame body, wherein a water delivery end of the submersible pump communicates with the water collection tank via a pipeline of the motor-pumped well; the transparent greenhouse ceiling is wave-shaped, and the overall transparent greenhouse ceiling forms a certain inclining angle relative to the horizontal direction; rainwater collection pipes are disposed at low-laying parts of the wave shape of the greenhouse ceiling, and water outlet ends of the rainwater collection pipes communicate with the water collection tank; and a solar photovoltaic panel is installed on raised parts of the wave shape of the greenhouse ceiling via a support. According to the invention, the water collection tank is disposed to collect underground water pumped out by the submersible pump and rainwater collected by the rainwater collection pipes and the water is used for spraying irrigation, so that Hetao water is not used, and the underground water level can be lowered and controlled. Soil of a saline-alkali land is taken as planting soil of a planting soil layer, so that plant plantation is achieved.

Description

technical field [0001] The invention belongs to the technical field of saline-alkali land improvement, in particular to a greenhouse system for saline-alkali land in the Hetao irrigation area. Background technique [0002] The Hetao area refers to the "Ji" bend of the Yellow River and its surrounding basins. The large-scale irrigation district in the middle reaches of the Yellow River is the irrigation district with the largest designed irrigation area in China. Affected by unreasonable man-made measures in some areas of the Hetao Irrigation District, a large amount of irrigation water leaked, which caused the groundwater level to rise, resulting in soil salinization and the formation of saline-alkali land in the Hetao Irrigation District. The key to prevention and control is to control the groundwater level and improve the irrigation and drainage system. For the improvement of the Hetao saline-alkali land, there is a lack of a planting system that does not use Hetao water...
