摘　　要：以普通地膜为对照,探究绿色地膜、银灰地膜、除草地膜(乙草胺)覆盖对土壤水分和温度及甘蔗出苗的影响,为不同颜色地膜在甘蔗栽培上的应用提供理论参考。结果表明,不同颜色地膜覆盖对土壤水分影响情况是普通地膜>绿色地膜>除草地膜>银灰地膜,普通地膜和绿色地膜相对保水效果较好,均高于银灰地膜和除草地膜,但无统计学意义;土壤温度是普通地膜=除草地膜>绿色地膜>银灰地膜。甘蔗出苗率、分蘖率变化均无明显差异,银灰地膜相对较差。The effect of green plastic film,sliver gray plastic film and herbicidal plastics film(acetochlor)on soil moisture and temperature and sugarcane germination were studied with common plastic film as control to provide theory reference for applying different color film mulching on sugarcane cultivation.The results showed that the impact orders of different color film mulching on soil moisture were the common plastic film>green plastic film>herbicidal plastics film>sliver gray plastic film.The relative water conservation effect of the both common plastic film and green plastic film were better than that of the sliver gray plastic film and herbicidal plastics film,but there were no statistically significant differences.The impact orders of different color film mulching on soil temperature were the common plastic film=herbicidal plastics film>green plastic film>sliver gray plastic film.Moreover,the change of sugarcane germination percentage and tillering rate were no significant differences except that the sliver gray plastic film was relatively poor.
