Abstract

The invention relates to an intelligent variable rate fertilization adjustment device and a control method. The intelligent variable rate fertilization adjustment device includes a frame traction device, a deep loosening soil preparation device, a variable rate fertilization device and a variable rate fertilization control device. The deep loosening soil preparation device includes a rotary tilling device and a deep loosening device. The variable rate fertilization device includes a single fertilization device, a fertilizer discharge pipe, a fertilizer box and an electrical control box. The variable rate fertilization control device includes an embedded industrial personal computer, a single chip microcomputer, an opening degree adjustment stepped motor driver, a speed adjustment stepper motor driver, an opening degree sensor, a speed sensor and a soil nitrogen content sensor. Variable adjustment in the fertilization process can be realized according to the nitrogen content of soil, and precision fertilization for each position of a plot can be realized. Moreover, the intelligent variable rate fertilization adjustment device has the advantages of simple structure, reasonable designand easy popularization, the problem of fertilizer application in the process of crop fertilization can be fully solved, fertilizers can be effectively utilized, and environmental pollution and wasteof fertilizers can be avoided.

Description

technical field [0001] The invention relates to an intelligent variable fertilization device and a control method, in particular to a novel, highly efficient and fertilizer-saving variable fertilization adjustment, which is applied to crop fertilization in the crop production process and belongs to the technical field of agricultural machinery. Background technique [0002] Variable fertilization technology is an important part of precision agriculture, and has achieved significant economic and social benefits abroad. Variable-variable fertilizer applicators have been studied in depth in developed countries, and their related technologies have been perfected and commercialized day by day. As early as the 1990s, the United States carried out the application of soil testing and formula fertilization technology, and the United Kingdom, Germany, Canada, Australia and other countries also carried out research and application one after another, while my country only began to apply...
