Abstract

The invention discloses a branch detection type water and fertilizer integrated irrigation system and a control method. The system comprises a main water pipeline, a branch pipeline, a fertilizer suction device and a water and fertilizer integrated control system. The fertilizer suction device comprises a venturi tube, a fertilizer mixing tank, a branch pipeline check valve and the like. The waterand fertilizer integrated control system comprises an electric flow regulating valve, an electromagnetic flow meter, a PH sensor, an EC sensor and a programmable logic controller. The water and fertilizer integrated intelligent control system realizes follow-up control of openness of the electric flow regulating valve according to detected PH/EC values so as to continuously adjust fertilizer concentration to keep in a certain range. Accurate, intelligent and automatic management of water and fertilizers is realized, and low cost and availability for utilization in severe environments are realized.

Description

technical field [0001] The invention belongs to the field of irrigation, and in particular relates to a water and fertilizer integrated irrigation system and method for branch detection, which is suitable for smart agriculture and can realize water and fertilizer integration and automatic management. Background technique [0002] Water is the source of life and a necessary condition for the development of agricultural production; fertilizer is an important guarantee for increasing agricultural production and high yield. The traditional fertilization method is to fertilize first and then water. This production method has brought about a series of problems such as waste of water and fertilizer resources, soil acidification, and water environmental pollution. It has become a bottleneck restricting the sustainable development of China's agriculture. The integration of water and fertilizer is a new technology of high-efficiency water-saving and fertilizer-saving agriculture recog...
