Abstract

The invention relates to a system and method for disinfecting a soilless culture medium. The system for disinfecting the soilless culture medium comprises a drip irrigation system, a medium groove, a liquid storage pool, a liquid storage barrel and an electrolysis device. The drip irrigation system is arranged above the medium groove. The bottom of the medium groove is connected with the liquid storage pool through a liquid return pipe. Two submerged pumps are arranged at the bottom inside the liquid storage pool. One submerged pump is connected with the liquid storage barrel through a filter. The liquid storage barrel is further connected with an inlet of the electrolysis device through a booster pump. An anode liquid outlet of the electrolysis device is connected with the drip irrigation system through an anode terminal liquid return pipe and a cathode liquid outlet is connected with the liquid storage pool through a cathode terminal liquid return pipe. The invention further provides the method with the system for disinfecting the soilless culture medium adopted. According to the system for disinfecting the soilless culture medium, a disinfecting closed loop and a nutrient solution supply closed loop are obtained through a three-way valve, the automation degree is high, the energy consumption is small, pathogenic microorganism generated in the medium is thoroughly killed, occurrence and transmission of root transmission diseases can be effectively controlled, and residue and pollution are avoided.

Description

technical field [0001] The invention relates to a soilless cultivation substrate disinfection system and method, belonging to the field of soilless cultivation of facility vegetables. Background technique [0002] Soilless cultivation gets rid of the limitation of soil on agricultural production. Light materials such as peat, vermiculite, and rock wool are used as cultivation media, and at the same time, watering nutrient solution is used to provide sufficient water and nutrients for crops. Compared with soil cultivation, soilless cultivation can create a rhizosphere environment suitable for crop growth by adjusting the composition and characteristics of nutrient solution, and at the same time prevent crop physiological obstacles caused by continuous cropping and soil salt accumulation. [0003] According to whether the nutrient solution is recycled or not, soilless cultivation can be divided into open and closed methods. In the open soilless cultivation system, since the n...
