Abstract: Aiming at the problems of poor uniformity,low efficiency and shallow furrow of traditional grape organic fertilizing machine,a new kind of grape organic fertilizing machine was designed.The machine consists of four parts:power transmission system,furrow device,fertilization device and hydrulic device.It can furrow deeply,fertilize and cover soil at one time.The results showed that the variation coefficient of the uniformity of fertilization was 11.96%,the brake rate was 0,the averaged fertilization depth was 44.9 cm,and the averaged distance between the root and the fertilizer was 58.1 cm.

Key words: grape fertilizing machine, organic fertilizer, hydraulic pressure
