Problems solved by technology
[0002] Due to problems such as population growth, reduction of arable land, resource shortage, and environmental degradation, traditional food crop production faces huge challenges in terms of yield and safety.
In order to cope with this situation, plant factories emerged as the times require. In order to meet the nutritional needs of plant growth, nutrients need to be supplemented artificially. It is an ideal choice to replace traditional water irrigation with nutrient solution rich in various nutrients; Water is used to export the nutrient solution used by plants for purification and reuse. It is necessary to design a set of efficient and fast nutrient solution circulation treatment system. However, many circulation treatment systems in plant factories cannot achieve the desired effect. The bacteria are not thorough, the effluent contains suspended solids of small particle size, and the concentration of each ion in the nutrient solution cannot be monitored in real time and automatically adjusted, etc.

Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings of the description.
[0016] Firstly, prepare the nutrient solution at the initial stage of system operation, the real-time monitoring control system 9 automatically opens the solenoid valve F1, controls the condensed water tank F to add condensed water to the nutrient solution pool 1, and reads the data from the first liquid level gauge 2 to control the total amount in the pool. According to the nutrient composition and demand required by the cultivated plants, the real-time monitoring and control system 9 automatically controls each nutrient solution mother liquid tank, adds nutrients to the nutrient solution pool 1, and removes impurities in each mother liquid irrigation through the filter group 5 such as adding the mother liquor calcium nitrate A in the mother liquor tank, the real-time monitoring and control system 9 calculates the required amount as required, then op...

The invention discloses a system achieving automatic control and circulating utilization of a plant nutrient solution. The system is mainly composed of a nutrient solution automatic circulating system, a nutrient solution ion composition online monitoring and controlling system, a nutrient solution online monitoring hardware system and the like, and the system can be used for plant factories and long-term plant cultivation tests and can also be applied to circulating utilization of a nutrient solution for cultivating crops in water shortage areas such as plateaus, deserts and frozen soil. According to the system achieving automatic control and circulating utilization of the plant nutrient solution, the structure is simple, full-automatic real-time monitoring is achieved, operation is convenient, the purification effect is good, the energy utilization rate is high, and the system particularly solves the problem that the labor force is insufficient in a special environment.
Description
technical field [0001] This patent relates to an automatic regulation and recycling plant nutrient solution system, which can be used in plant factories and long-term plant cultivation experiments; it can also be applied to crop cultivation nutrient solution recycling in water-deficient areas such as plateaus, deserts, and frozen soils. The structure of this patent is simple , Fully automatic real-time monitoring, easy operation, good purification effect and high energy utilization rate. Background technique [0002] Due to population growth, reduction of arable land, resource shortage, environmental degradation and other issues, traditional food crop production is facing huge challenges in terms of yield and safety. In order to cope with this situation, plant factories emerged as the times require. In order to meet the nutritional needs of plant growth, nutrients need to be supplemented artificially. It is an ideal choice to replace traditional water irrigation with nutrien...
