Combined stereoscopic water culture device and method

Abstract

The invention discloses a combined stereoscopic water culture device and method. The combined stereoscopic water culture device comprises a plurality of water culture boxes, wherein the plurality of water culture boxes are placed in a superposed and combined manner, a first water overflow column, a second water overflow column and a third water overflow column are arranged in each water culture box, a fixed round pipe vertically penetrates through the water culture boxes, a plurality of planting holes are formed in the peripheries of the stereoscopic water culture boxes, casings for planting are inserted into the planting holes, and a water pump is placed in the water culture box at the bottommost layer and is used for pumping nutrient solution into the topmost water culture box through an arranged delivery pipe at fixed time. Since the device is simple, runs reliably, is simple to maintain and is convenient to assemble, the device is suitable for forming large-scale planting factories through combination for standard, intensive and high-efficiency planting production; the manufacturing costs of facilities can be greatly reduced, the technical thresholds of use and maintenance are reduced and the yield is greatly improved.

Description

technical field [0001] The invention relates to the field of soilless cultivation, in particular to a combined three-dimensional hydroponic device and method. Background technique [0002] As an advanced planting method, soilless culture has successively appeared matrix culture, hydroponics, and aerosol culture, subdivided into organic matrix culture and inorganic matrix culture; deep flow liquid hydroponics, shallow flow liquid hydroponics, tidal culture, and aerosol culture Wait. In many soilless cultivation methods, it is necessary to provide water, nutrients and oxygen to the plant root system. Water and nutrients are all realized through the nutrient solution, and the supply of oxygen is different in various ways. The substrate culture is similar to the soil, and the oxygen is supplied through the air permeability of the substrate; the hydroponics supplies oxygen through the dissolved oxygen in the nutrient solution; Aeroponics supplies oxygen through the mixture of w...

AI Technical Summary

Problems solved by technology

[0005] Three-dimensional cultivation using aerosol cultivation, first of all, requires relatively high pressure, transmission pipes and nozzles to convert the nutrient solution into mist, the device cost is high, maintenance technology requirements are high, and there are also disadvantages such as high energy consumption and high noise.

The more important disadvantage is that the ability to resist power failure is weak, and a power failure of tens of minutes may cause the death of plants cultivated for several months

[0006] Other methods, such as tidal culture and hydroponics, are more restricted in the application of three-dimensional cultivation

For example, the waterproof requirements and aeration measures of hydroponics; the drop requirements and waterproof requirements of tidal culture, etc., due to many restrictions and difficulties, it is difficult to flexibly assemble into the required three-dimensional cultivation shape according to the needs

[0007] Due to the above reasons, hydroponics, a high-tech planting method, has been difficult to promote and apply on a large scale for decades.
