Abstract: According to the agronomic planting characteristics of Xinjiang orchards, this paper designs a rear-hanging ditch fertilizing and covering machine.The machine uses a herringbone shovel opener to create a certain depth of groove on the ground, the depth can be adjusted in the range of 20 cm-30 cm, fertilize in the groove opened, and finally use a double disc type soil cover mechanism to complete the soil cover operation.Through field tests, the ditching depth, fertilization depth, fertilization uniformity and soil covering effect of the machine have reached the technical requirements.When the operating speed is 2 km/h, the overall operation of the implement is relatively stable. When the operating speed reaches 3 km/h, the fluctuation of the implement is significantly enhanced, and the depth of the ditch and the fertilization depth are significantly changed.During the operation, there is no fertilizer blocking phenomenon, and the effect of covering soil is good.The overall mechanism of the machine is simple, the operation is convenient, the operation performance is relatively stable, it has a good effect of ditching fertilization and covering the soil, and can meet the agronomic requirements of orchard fertilization.
