Large-scale hydroponic soilless culture device

Abstract

The invention relates to a large-scale hydroponic soilless culture device. The large-scale hydroponic soilless culture device comprises a liquid storage tank, a culture bed and a filtering device. The liquid storage tank is provided with a water outlet and a water inlet, the water outlet of the liquid storage tank is communicated with one end of the culture bed through a water inlet pipe, the other end of the culture bed is communicated with the water inlet of the water storage tank through a water return pipe, and a water pump is arranged between the water outlet of the water storage tank and the water inlet pipe. The large-scale hydroponic soilless culture device is characterized in that the filtering device comprises a water inlet filtering component and a water return filtering component, the water inlet filtering component is arranged between the water pump and the water inlet pipe, and the water return filtering component is arranged between the water inlet of the water storage tank and the water return pipe; the whole of the water return filtering component is a three-stage screen filter. The large-scale hydroponic soilless culture device has the advantages that due to the fact that the water inlet filtering component and the water return filtering component are designed for filtering nutrient solutions twice and the three-stage screen filter is adopted in the water return filtering component, the nutrient solutions can be recycled, and the large-scale hydroponic soilless culture device is beneficial to popularization in a large scale, simple in structure and little in investment.

Description

technical field [0001] The invention relates to a soilless cultivation device, in particular to a large-scale hydroponic soilless cultivation device. Background technique [0002] Soilless cultivation refers to the method of cultivating crops with nutrient solution or solid substrate plus nutrient solution without using natural soil; soilless cultivation is to replace the soil environment with the artificially created root environment of crops, in addition to satisfying the needs of crops for mineral nutrition, water and oxygen. In addition to the needs of the environment, these environments can also be manually controlled and adjusted, so that the products produced by it are superior to soil cultivation in terms of quantity and quality; , weeding and other labor processes, and gradually realized mechanization or automation in the whole soilless cultivation production, greatly reducing labor intensity, saving labor, and improving labor efficiency; , Soil secondary salinizat...

Problems solved by technology

The application of soilless cultivation in my country started relatively late, and is still in the stage of development and testing. In order to achieve large-scale, intensive and automated production of soilless cultivation, a large investment in equipment and high technical requirements are required, so it is not easy to scale up.
