Problems solved by technology
[0002] Drought, water shortage, backward technical level, and serious lack of scientific and technological innovation capabilities are important obstacles restricting the sustainable development of my country's agriculture. The traditional irrigation model has extensive water management and poor accuracy of fertilizer ratio, which not only seriously wastes water resources and fertilizers. Raw materials are not conducive to the growth of crops, and cause a certain degree of pollution to the environment. At the same time, the existing technology is relatively cumbersome for the accuracy detection of soil components in the crop growth environment, and the environmental requirements are high, which hinders the effective water and fertilizer required by the crops. Precise Irrigation Control Technology of Concentration Ratio

The invention discloses a device and method for online detection of active ingredients in soil, which includes a water passage and a nutrient solution passage. The nutrient solution passage is mixed with the water passage and then connected to the entrance of the water and fertilizer mixing passage. The nutrient solution passage is connected to the water and fertilizer mixing passage through a fertilizer pump. The water and fertilizer mixing passages are connected to the sampling and detection system. The water passage, the nutrient solution passage and the water and fertilizer mixing passages are all equipped with flow control meters. The nutrient solution passage, the water and fertilizer mixing passage and the sampling and detection system are all equipped with solenoid valves. All flow control meters and solenoid valves are all connected to the host computer control system. The invention has reasonable design, simple structure, easy operation, good equipment stability and reliability, and high degree of intelligence. It can effectively solve the intelligent problems existing in the existing water and fertilizer proportioning irrigation systems. There are many defects and deficiencies such as low degree of chemicalization, rough artificial operation, excessive use of water and fertilizer.
Description
【Technical field】 [0001] The invention belongs to the field of agricultural irrigation and electromechanical control, and in particular relates to a device and method for online detection of effective components in soil. 【Background technique】 [0002] Drought, water shortage, backward technology level, and serious lack of scientific and technological innovation capabilities are important obstacles restricting the sustainable development of agriculture in my country.
