Water and fertilizer integrated system for greenhouse

Abstract

The invention provides a water and fertilizer integrated system for a greenhouse. A structure of the water and fertilizer integrated system comprises a water well, wherein the water well is connected with a three-way connector through a water outlet pipe; the three-way connector is respectively communicated with water inlets of the water well, a non-purified water tank and a water purifier; a water outlet of the water purifier is communicated with a purified water tank through a pipeline; a common water pump is arranged on the non-purified water tank and the purified water tank; a water outlet of the water pump is communicated with a water and fertilizer mixing tank through a pipeline; the water and fertilizer mixing tank is communicated with a drip irrigation system; and the pipelines are respectively provided with valves. According to the water and fertilizer integrated system disclosed by the invention, purification or no purification is selected according to water quality, so as to provide better growth conditions for plants in the greenhouse.

Description

technical field [0001] The invention relates to a greenhouse water and fertilizer integrated system. Background technique [0002] At present, many modern agricultural enterprises use drip irrigation when irrigating greenhouses. When the temperature is high in summer, the evaporation effect is strong, and the concentration of impurities in the water is high. The irrigation water for drip irrigation should be purified before drip irrigation, otherwise the plants are susceptible to diseases. , also affect the normal growth of plants. In winter, when the evaporation effect is weak, the water does not need to be purified. At present, there is no integrated water and fertilizer system for greenhouses that can choose to purify or not purify water. Contents of the invention [0003] The purpose of the present invention is to provide an integrated water and fertilizer system for greenhouses, which can choose to purify or not purify water according to water quality, so as to provi...
