Abstract: According to the development of the agricultural machine in our country, the demand of the depths loosen machine is increased quickly. Therefore, a digital display of multifunctional depths loosen machine has designed. Refers to the experiment standard of JB/T6274.1-2001 The grist seeding-machine requirement GB/T5668.1-1995 The rotary tillage machinery experiment method JB/751016-1999 The gushing pole spraying machine product quality analysis. This article that proceeds from two mostly ways of interior function test and field experiment discusses the technology of agricultural machines. The machinery will bring both manufacturer and the owner of agricultural machinery. At the same time, it also has evident social benefit. This machinery can be operated easily, maintained conveniently and it has very high credibility. It’s foreground of popularize is wider.
