Fish vegetable commensalism water fertilizer processing system and method

Abstract

The invention relates to the technical field of soilless culture, in particular to a fish vegetable commensalism water fertilizer processing system and method. The fish vegetable commensalism water fertilizer processing system includes a primary solution storage device, a pressure mixing device, a slow releasing device, a spraying device, and a control device; the primary solution storage device is connected to a material inlet of the pressure mixing device through a first pipe, solenoid valves are arranged on the first pipe; the slow releasing device and the spraying device are connected to two material outlets of the pressure mixing device through pipes respectively; first proportional valves are arranged on the pipes; the solenoid valves and the first proportional valves are connected to the control device. The slow releasing device is started to apply a fertilizer in an early stage and a ripe stage of a crop; the slow releasing device and the spraying device are started in a vigorous stage of the crop, the slow releasing device is started to supply a macroelement nutriment solution, the spraying device is started to supply a microelement nutriment solution, accurate high efficiency fertilization and fertilizer supplement can be achieved, the fertilizer can be efficiently utilized, the yield and the quality of vegetables can be improved, the growth time of the vegetables is shortened, the working load is reduced, and intelligent accurate water fertilizer management can be achieved.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to a fish and vegetable symbiosis water and fertilizer treatment system and method. Background technique [0002] As the population continues to grow and resources and energy continue to decrease, the pressure on the ecological environment is becoming more and more pressing. Traditional arable land agriculture is facing enormous pressure and many problems. [0003] Soilless cultivation and integration of water and fertilizer is an effective means to solve the plight of traditional agricultural development. The fish and vegetable symbiosis model combines circulating aquaculture and soilless cultivation technology, uses water treatment technology to recycle aquaculture wastewater, and then uses it as waste water. Soil cultivation and nutrient solution cultivation of vegetables have the characteristics of remarkable ecology, high efficiency and sustainability. The nutrien...
