RESEARCH ON CONSERCATION TILLAGE TECHNOLOGY OF WHEAT IN THE CHENBAERHU BANNER

The phenomenon of drought,low rainfall,extensive farming,soil erosion,wind erosion,black land degradation and desertification is more serious.And according to the characteristics which natural disasters such as drought,sandstorms,floods and frost and so on have occurred alternatively in recent years,the wheat comparative experiment research was made by the method of conventional tillage and traditional tillage.In this paper,under the method of no-tillage straw mulch and deep-loose straw mulch,some factors such as soil bulk density,soil temperature,soil water retention and crop condition and yield are focused.The results show that,compared with traditional tillage,the conservation tillage is benefit for soil water retention,can reduce soil bulk density,and increase the crop production slightly,and make good effects on the economy,society and ecology.
