摘要 根据多年定位试验资料,讨论了一种新型的农田覆盖材料-草纤维膜,覆盖农田对土壤理化性质,土壤温度,土壤水分状况以及作物生长发育的影响,并与塑料地膜覆盖农田的生态效应进行了比较,结果表明,草纤维膜与塑料地膜覆盖具有改善土壤结构,增强作为对土壤肥料的有效利用,改善作物生长的土壤温度状况,减少土壤无效蒸发和提高水分利用效率的作用,与塑料地膜相比,草纤维膜覆盖没有污染土壤的副效应,因此是解决我国北方旱农区“ 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.
