According to the observed field information from the place located in Shuoyang County(Shanxi Province),this paper discussed a new kind of field mulch-grassy fibre film mulch(GFFM)and contrasted its effects with those of plastics film mulch(PFM)on soil physico-chemical feature,soil temperature,soil water condition and the growth and development ofSpring maize,The results indicate that GFFM and PFM could improve soil structure,harmo-nize relations between soil temperature,soil water condition and crop development,decreasesoil evaporation,raise crop water utilization efficiency. Compared with PFM,GFFM has nobad effect of soil pollution so,the GFFM would be one of the effective ways to solve the“drought”and “poor” problem in the dry farming areas of Northern China.
