System for water-fertilizer-pesticide integral automatic irrigation with nitrogen-phosphorus-potassium online detection function

Abstract

The invention discloses a system for water-fertilizer-pesticide integral automatic irrigation with a nitrogen-phosphorus-potassium online detection function. The system is characterized in that technologies such as an embedded system control technology, a database technology, an information collection and transmission technology and a frequency-conversion and multi-channel partitioned control technology are adopted for remote control of concentrations and flow rates of water, fertilizers and pesticides, and the water, fertilizers and pesticides can reach plant roots via an irrigation pipeline system; users and experts can monitor crop growth conditions, soil demands for water, fertilizers and pesticides and climate environmental parameters at any time so as to conduct network-based supervision and control of crops in a plantation area; remote control of water irrigation, fertilization and pesticide application can be conducted effectively in time; and complete technologies and methods suitable for intelligent and remote control of irrigation, fertilization and pesticide application in water-saving agriculture are formed; and thus, automation, intelligence and informationalization levels of the irrigation system are increased, and purposes of water saving, fertilizer saving, pesticide saving, yield growth and income increase are achieved.

Description

technical field [0001] The invention relates to an irrigation system, in particular to an automatic irrigation system integrating water, fertilizer and medicine with an online detection function of nitrogen, phosphorus and potassium, and belongs to the technical field of agricultural equipment. Background technique [0002] Most of Xinjiang is an arid area with precipitation less than 200mm, 94% of the arable land in Xinjiang is irrigated agriculture, and the water shortage in spring is 1.5×109m 3 ~2.0×109m 3 Therefore, water-saving irrigation is the only way for Xinjiang agriculture, and it is the key to alleviating the shortage of water resources in Xinjiang, improving the utilization rate of water resources, realizing efficient and sustainable use of water resources, and the sustainable development of agriculture. [0003] To develop water-saving irrigation, micro-irrigation, drip irrigation and other irrigation systems need to be equipped with corresponding control head...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the automatic irrigation equipment for water, fertilizer and medicine is foreign technology, which is expensive, operation and maintenance are very difficult, and farmers and technicians often have no countermeasures.
