A fish and vegetable symbiosis water and fertilizer treatment system and method

Abstract

The present invention relates to the technical field of soilless cultivation, in particular to an aquaponics symbiosis water and fertilizer treatment system and method, comprising a raw liquid storage device, a pressure mixing device, a slow application device, a spraying device and a control device. The raw liquid storage device passes through a first pipeline and a pressure The feed port of the mixing device is connected, the first pipeline is provided with a solenoid valve, the slow application device and the spraying device are respectively connected to the two discharge ports of the pressure mixing device through the pipeline, the first proportional valve is provided on the pipeline, and the solenoid valve Both the valve and the first proportional valve are connected to the control device. In the present invention, only the slow application device is started to fertilize in the early stage of crop growth and the mature stage, and the slow application device and the spraying device are started at the same time during the vigorous period, the slow application device is started by supplementing a large amount of nutrient solution, and the spraying device is started by supplementing a trace element nutrient solution, so as to realize accurate Efficient fertilization and supplementation of fertilizers have the characteristics of efficient use of fertilizers, significantly improved vegetable yield and quality, shortened vegetable growth time, and reduced labor intensity, achieving intelligent and precise water and fertilizer management.

Description

Technical field [0001] The invention relates to the technical field of soilless culture, in particular to a fish-vegetable symbiotic 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 urgent. Traditional farmland agriculture is facing tremendous pressure and many problems. [0003] The integration of soilless culture and water and fertilizer is an effective means to solve the dilemma of traditional agricultural development. The fish-vegetable symbiosis model combines circulating aquaculture and soilless culture technology, using water treatment technology to resource aquaculture wastewater, and then use it as a Soil cultivation and nutrient solution cultivation of vegetables has obvious characteristics of ecology, efficiency and sustainability. The nutrient of the soilless culture cycle comes from the b...
