Soilless culture device and control method

Abstract

The invention discloses a soilless culture device and a control method. The device comprises a container cover, a ventilation hole, a culture frame, a container, a baffle cushion, a first container baffle layer, a water supply pipe, a water injection electromagnetic valve, a second container baffle layer, a water source pipe, a fertilization electromagnetic valve, a fertilizer supply pipe, a controller, a display touch screen, a first electrode, a second electrode, a third electrode, a columnar support and a hydrophilic fiber net. The culture device disclosed by the invention is characterized in that by the culture frame which is made specially, puzzles of supply of water, oxygen and mineral nutrients in soilless plant culture are solved scientifically at low cost; detection and control of EC values and humidity in the soilless culture are simple and practical; and online monitoring and management at different places become possible. The device and the method disclosed by the invention are especially applicable to intelligent culture of home potted plants. The culture device has the advantages that the structure is simple; use is easy; and promotion is easy.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a soilless cultivation device and a control method, which are suitable for intelligent cultivation of potted plants. Background technique [0002] Soilless cultivation of plants generally adopts substrate cultivation, hydroponics or aerosol cultivation. Hydroponics is to immerse the plant roots directly in the nutrient solution to grow. However, this method will cause the roots to be hypoxic. The oxygen concentration in the nutrient solution must be controlled by pumping oxygen, and it is also necessary to use the cultivation board to fix the plants, causing management problems. Difficulties and cumbersomeness. Aerosol culture compresses the nutrient solution into an aerosol and sprays it directly on the roots of the crops, directly applying the oxygen in the air. This method solves the problem of lack of oxygen in the roots during hydroponics, but the equipment investment for nutri...

AI Technical Summary

Problems solved by technology

However, matrix cultivation needs to control the instillation of nutrient solution through drippers, etc. During production, the requirements for control and management are relatively high.

In addition, the cultivation medium has high costs in the process of production, packaging, and transportation, and it is difficult to recycle it twice, which also has a great impact on the environment.

Existing cultivation methods, including matrix cultivation, hydroponics and aerosol cultivation, are difficult to realize in automatic control, especially it is difficult to realize the automatic control of small cultivation devices

Among them, hydroponics has a high cost of testing equipment for oxygen detection and control; substrate cultivation and aerosol cultivation have relatively high cost of equipment investment in irrigation control, and have high requirements for the stability of equipment

These factors have made it difficult for traditional small-scale cultivation devices to be automated and intelligently controlled.
