Abstract

The invention discloses a soilless cultivation device and a control method. The device comprises a container cover, a ventilation hole, a cultivation frame, a container, a spacer, a first container interlayer, a water supply pipe, a water injection solenoid valve, a second container interlayer, Water source pipe, fertilization solenoid valve, fertilizer supply pipe, controller, display touch screen, first electrode, second electrode, third electrode, cylindrical support, hydrophilic fiber net; the cultivation device of the present invention uses a special cultivation frame, Scientifically and at low cost, it solves the problem of water, oxygen and mineral nutrient supply in soilless cultivation of plants, and makes the detection and control of EC value and humidity in soilless cultivation simple and easy, and online monitoring and management in different places becomes possible. The invention is particularly suitable for intelligent cultivation of household potted plants. The cultivation device has a simple structure, is easy to use, and is easy to popularize.

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 aeroponics. Hydroponics is to directly immerse the plant roots in the nutrient solution to grow, but this method will cause the roots to lack oxygen. The oxygen concentration in the nutrient solution must be controlled by pumping oxygen, and the plant needs to be fixed through the cultivation board, causing management. difficulties and tediousness. Aerosol culture compresses the nutrient solution into an aerosol and sprays it directly on the roots of the crops, and directly applies the oxygen in the air. This method solves the problem of lack of oxygen in the roots during hydroponics, but the equipment investment for nutrient solution atomization Compar...

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.
