Abstract
In order to ensure the quality of furrow fertilization, improve the efficiency of operation and reduce the cost of production, a kind of furrow fertilization machine with stable performance is needed. This design of orchard ditching fertilizer machine is mainly composed of walking tractor, ditching device, fertilizer device, lifting device and soil covering mechanism.
First of all, based on the analysis of the current situation, structure and principle of the orchard ditching and fertilizing machine, this paper puts forward its design scheme, which is characterized by simple and compact structure, low requirements for various parts, and easy production and processing; the machine works reliably and can better meet the ditching and fertilizing work of the orchard. Then, the main technical parameters are calculated and selected; then, the main parts are designed and checked; finally, the assembly drawing and main parts drawing are drawn by AutoCAD drawing software, and three-dimensional design is carried out.

Key words: Orchard; Ditching Device; Fertilization Device; Soil Covering Device
