Abstract

The invention relates to a facility integrating rain regulation and control with fertilizer irrigation for a greenhouse cultivation. The facility provided by the invention comprises a rain collecting tank, a drain grating well, a sedimentation basin, a sand filter, a water reservoir and a fertilizer preparation tank; the bottom of the rain collecting tank is a slope-shaped structure, and the rain collecting tank is connected with the drain grating well through a rain flow guide pipe; the drain grating well is internally provided with a drain grating net and the drain grating well is communicated with a water guide opening on the upper end of the side wall of the sedimentation basin; a first grit chamber and a second grit chamber are arranged in front and back sides of the sedimentation basin in sequence; a baffle plate is arranged on a water inlet end of the first grit chamber and a flow guide pipe on a water outlet end is communicated with the second grit chamber; a water collecting weir is arranged on the upper part of the side wall on the tail end of the second grit chamber and is communicated with a water distributing pipe of the sand filter; the water distributing pipe is located at the bottom of the sand filter, a water collecting pipe is arranged on the upper part of the side wall on the tail end of the second grit chamber and is communicated with the water reservoir; a water guide pipe is arranged on one side of the water reservoir which is adjacent to the fertilizer preparation tank, the water guide pipe is respectively provided with a water output valve, a tap water valve and a water input valve. The facility provided by the invention has the advantages of rational design of structure, simplicity in operation, less investment, wide application, stability in operation and very obvious effects.

Description

technical field [0001] The invention relates to an agricultural irrigation facility, in particular to an irrigation facility for rainwater collection, regulation and fertilization for greenhouse cultivation. Background technique [0002] At present, my country's per capita water shortage is less than 2200m 3 , belongs to the lower middle level, and at the same time, my country is a large agricultural country. Under the dual pressure of cultivated land area and irrigation system, agricultural water use accounts for more than 60% of the country's water use. Under the premise that the cultivated land area cannot be reduced, only a variety of water can be developed. resource channels and improve the utilization of water resources. With the acceleration of urbanization in our country, in order to meet the huge demand of urban residents for vegetables, solar greenhouses have been developed rapidly. For example, in Tianjin, there is a large gap between agricultural irrigation water...
