Large-scale soilless culture nutrient solution management system

Abstract

The invention relates to a large-scale soilless culture nutrient solution management system. The large-scale soilless culture nutrient solution management system comprises a nutrient solution circulating tank, a nutrient solution state detecting device, a nutrient solution state regulating device and a control system and is characterized in that the nutrient solution circulating tank is used for providing a nutrient solution for a soilless culture facility; the nutrient solution state detecting device is mounted in the nutrient solution circulating tank and used for detecting the nutrient solution state in the nutrient solution circulating tank and transmitting the detected value to the control system; the nutrient solution state regulating device is communicated with the nutrient solutioncirculating tank, and the control system controls the nutrient solution regulating device to regulate the nutrient solution state in the nutrient solution circulating tank according to the detected value. The large-scale soilless culture nutrient solution management system has the advantages that by detecting the nutrient solution state in the nutrient solution circulating tank and using the nutrient solution state regulating device to regulate the nutrient solution state, automatic omnibearing management and control of the nutrient solution of the soilless culture system of fruit and vegetables of different varieties can be achieved, and stable and efficient production of the large-scale soilless culture device can be achieved.

Description

technical field [0001] The invention relates to the technical field related to soilless cultivation, in particular to a large-scale soilless cultivation nutrient solution management system. Background technique [0002] At present, the soilless cultivation commonly used in China mainly uses nutrient solution to grow various crops. The nutrient solution is generally replaced regularly, or the entire batch of nutrient solution is replaced after the turbidity value reaches a certain critical value during the planting period. However, if we want to ensure the efficient and stable output of the large-scale soilless cultivation system, we must ensure that the conductivity value, pH value, dissolved oxygen value, temperature value and turbidity value of the nutrient solution are stable within a certain range. The cost of nutrient solution is relatively high. If one piece of data does not match, it is very uneconomical to directly replace the entire batch of nutrient solution. Con...
