Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and in particular relates to an air pressure type fertilization and pesticide application device. Background technique [0002] Fertilizer is a kind of substance that provides essential nutrients for crops, improves soil properties, and improves soil fertility. When the soil cannot provide the nutrients needed for crop growth, fertilization must be carried out. Existing fertilizer spreaders are driven by the power output shaft to rotate the fertilizer spreader to spread the fertilizer by centrifugal force. There are two types of single disc and double disc, which have the disadvantages of complex structure and uneven fertilization. The fertilizer machine can only spread the fertilizer of solid particles, and does not have the function of spraying liquid fertilizer. Contents of the invention [0003] The object of the present invention is to provide an air pressure type fertiliza...
