Facility for rainwater collection regulation and control, fertilization and irrigation for greenhouse cultivation

Abstract

The invention relates to a facility for rainwater collection regulation and control, fertilization and irrigation for greenhouse cultivation, which comprises a reservoir, a fertilization pool and a water collection well. One side of the reservoir is connected with the fertilization pool, and the fertilization pool is communicated with the water collection well through a water distribution pipe; an upper part of the outside of the fertilization pool connected with the reservoir is provided with the water collection well parallel to the end face of the fertilization pool; the side walls of the water collection well are provided with a shed surface rainwater collection guide pipe, a pavement rainwater collection guide pipe and a tap water pipe which are communicated with the fertilization pool respectively; and a dirt blocking net is arranged in the water collection well, and a tap water control valve which is opened as required is arranged on the tap water pipe connected into the water collection well. The other side in the reservoir is provided with a sand suction pipe and a drop irrigation main pipe respectively; the end face of the reservoir is provided with a precast cover platein parallel; the reservoir is communicated with the fertilization pool through a water guide pipe; and a fertilizer feeding port is arranged above the corresponding fertilization pool. The facility can relieve limited water resources for sunlight greenhouses, effectively collect rainwater, optimize the water source, improve the night soil coupling and utilizing efficiency, and improve the ecological environment.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an irrigation facility for rainwater collection, regulation, fertilization and irrigation for greenhouse cultivation. Background technique [0002] Some places in China suffer from severe water shortages, such as Tianjin, where there is a large gap between the water supply and demand for agricultural irrigation. The area of ​​solar greenhouses in this area is increasing year by year, flood irrigation with large amounts of water and fertilizers is common, and relying on overexploitation of groundwater to maintain agricultural production will aggravate land subsidence and related related problems. Therefore, fully accumulating about 600mm of annual rainfall resources in this area combined with advanced drip irrigation technology will be the most effective measure to solve water shortage, water and fertilizer waste and environmental pollution. Fertilizer is an impor...
