旱地整地机械对比研究

Contrast Study of Soil Preparation Maclune on Dryland

通过对国内外旱地整地机械的类型、工作原理及应用的介绍，对其工作性能、动力性能及其影响因素进行了对比研究。可以看出，必须根据自然条件、农艺要求设计、选择合适的机具；必须恰当地协调影响机具性能的相互关系，是提高工作效果和生产率的关键；要结合我国实际，研究开发适合谷地条件的整地机械。

This paper introduces the types ,work principles and applications of soilpreparation machines for dryland at home and abroad. Contrast research has been doneon their working performance and power requirment.The result shows that designingand selecting suitable machines must based on the natural conditions and farming re-quirments. It is a key to improve working effect and productivity of the machines thatthe relationships to affecting machine performance should be coordinated.It is essentialto research and develop soil preparation machine suiting local conditions in our country.
