Abstract

The invention provides a dual-purpose fertilizing device capable of accurately preparing a fertilizer and irrigating clear water and an EC+PH adjusting method thereof. According to the device, a water feeding system and a fertilizer feeding system are arranged in a fertilizer mixing tank; a backflow pipeline is arranged on the fertilizer mixing tank and a fertilizer feeding pipeline; a fertilizer concentration acquisition device and a pH acquisition device are arranged on the backflow pipeline, and are connected with a fertilizer preparation control system respectively through data lines; and the fertilizer preparation control system is electrically connected with a fertilizer suction electromagnetic valve and a fertilizing pump. Key parameters of an algorithm and a control way are adjusted in real time according to a parameter change situation on the basis of a closed-loop control principle and PID (Proportion Integration Differentiation) adjustment and in combination with the object features of a fertilizer liquid reaction process, in particular the non-linear process features of PH parameter change, and accurate and stable control of EC and PH of a fertilizer liquid is realized by using a most proper control strategy and corresponding regulation and control parameters under different working conditions of a fertilizer preparation reaction process.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a dual-purpose fertilization device for precise fertilizer distribution and clean water irrigation and an EC+PH adjustment method thereof. Background technique [0002] In the 1970s, my country began to introduce irrigation and fertilization technology and carry out related technology research and promotion. Although great progress has been made in irrigation intelligent control, the country has not yet achieved breakthroughs in automatic precision fertilizer distribution control research and related equipment research and development. However, the most practical applications in China are still foreign fertilization systems such as Israel and Italy, and the system construction cost is expensive. Therefore, it is necessary to integrate multi-disciplinary and existing scientific research results to develop an economical and practical water and fertilizer i...
