Abstract

The invention discloses an automatic monitoring soilless culture device which comprises a trough body, a U-shaped drain pipe, a liquid level meter, a liquid inlet pipe, a solenoid valve, a PLC device and an alerter connected with the PLC device. The water inlet end of the U-shaped drain pipe is arranged on the bottom inside the trough body, the water outlet end of the U-shaped drain pipe is arranged outside the trough body, the height of the water outlet with the solenoid valve is smaller than that of the water inlet end, the liquid level meter is arranged in the trough body and is connected with the signal input end of the PLC device, and the liquid inlet pipe is arranged on the trough body and is communicated with the inner portion of the trough body. The automatic monitoring soilless culture device achieves automatic monitoring and alarm on culture media and culture environments of a soilless culture system. The automatic monitoring soilless culture device achieves the automatic monitoring and alarm on the content of culture solutions in a culture process, reduces difficulty of soilless culture, and improves culture efficiency.

Description

[0001] technical field [0002] The invention relates to a soilless cultivation device, in particular to an automatic monitoring soilless cultivation device. Background technique [0003] Historically, the symbol of agricultural civilization is the degree of human intervention and control over crop growth and development. Practice has proved that it is relatively easy to control the environmental conditions of the aboveground part of the crop, but it is very difficult to control the underground part (root system control) under conventional soil culture conditions. The emergence of soilless cultivation technology has enabled human beings to obtain the ability to precisely control all environmental conditions for crop growth, including inorganic nutritional conditions, so that agricultural production may completely get rid of the constraints of natural conditions and completely follow human wishes. Towards automation, mechanization and factory production methods. This wi...
