Abstract

The present invention relates to the field of fertilization technology, and especially relates to a fertilization test platform, which comprises a soil tank, a trolley, an air-conveying fertilizer apparatus and a measurement and control system. The trolley is arranged on a track and is driven to move along the direction of the track by a hydraulic motor. The air-conveying fertilizer apparatus comprises a motor, a fan, a fertilizer applicator, a fertilizer sowing pipe and an air supply pipe. The motor drives the fertilizer applicator to convey the fertilizer into the fertilizer sowing pipe. One end of the air supply pipe is connected with the fertilizer sowing pipe, and the other end of the air supply pipe is connected with the fan. The measurement and control system comprises a control unit and an acquisition unit. The acquisition unit comprises an air pressure sensor, an air speed sensor and a speed measurement encoder. By means of the fertilization test platform, the condition of a paddy field can be repeatedly simulated. Meanwhile, during the air-conveying fertilizer sowing process, parameters such as air pressure, air speed, the displacement of the trolley, the speed of the trolley and the like, can be acquired and processed in real time. Therefore, the fertilizer sowing amount of a fertilizer sowing wheel at different rotation speeds in different intermittent rotation conditions and the distribution state of the fertilizer can be tested.

Description

technical field [0001] The invention relates to the technical field of fertilization, in particular to a fertilization test bench. Background technique [0002] In the process of rice production in my country, the fertilization link has been using artificial hand fertilization. This fertilization method applies a large amount of fertilizer, and the fertilizer is unevenly distributed in the field, and the amount of fertilizer absorbed by the rice seedlings is inconsistent, resulting in great differences in the growth, height, and ear size of the rice, which directly affects the rice yield. With the drainage of the production process, the water containing fertilizers is discharged into rivers, which seriously pollutes production and domestic water. At present, the ideal fertilization method is "rice side deep precision fertilization", which can well ensure the positioning, quantitative, uniform and reliable fertilization of rice transplanting, and can ensure uniform and stabl...
