| Protectionability cultivation is the trend of agricultural development. The machinery can increase the soil organic matter, improve structure of the soil, avoid water erosion and wind erosion, strengthen soil fertility,heighten grain output and it can be made for agricultural sustainable development. zero tillage coverage fertilization can less the pieces of agriculture, increase the availability of chemical fertilizer and it can reduce activity cost .this mode can save operating time as well as improve the quality and quantity of crops. the machinery of protectionability cultivation, especially, the experimentalize of exemptlillage machinery have just began in our country. it has less function and has no intelligence ,2BMXS-3/10 numerical display versatile exempttillage sowing machine has the ability totillage, sow, fertilize, shootpoison ous water ,numerical display and soon. It's a compound exenpttillage machinery which is widely used and high utility.soitis really asymbol. But it can't work for longer time. So some part of it is not mature and researched on, it is meaningful.This thesis covers the analyzing the experiment of mended-digital display (DD)zero tillage circumrotate machinery ,its capability and technical indicators as follows: Firstly, a tractor serves several purposes; Secondly, good flexibility; Thirdly, choiceness performance and credibility;Fourthly, expanding serviceable range; Fifthly, improving the quality of labor;Sixthly, supplying another choiceness equipment;Seventhly, picking up agricultural continuable development.After analysis the economical efficiency of 2BMXS-3/10 , and predicting its being extended feasibility ,once it will launch ,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.
