摘　　要：为推动全生物降解地膜在辣椒大田生产中的应用,筛选适宜的全生物降解地膜产品,对比了淀粉基、PBAT+PLA、PBAT+PLA+PHA 3种不同成分的全生物降解地膜在辣椒大田生产中的应用效果。结果表明:以PBAT为主要成分的2种黑色全生物降解地膜BM2、BM3对辣椒株高、开展度、茎粗、根系干质量均有促进效果,且均显著促进辣椒增产,比对照分别增产67.8%、72.7%;2种地膜降解规律适用于辣椒大田生产,残膜不影响农机罢园翻耕作业,在武汉地区春季辣椒大田生产中,可以应用Ⅱ类以PBAT为主要成分的黑色全生物降解地膜。In order to promote the application of biodegradable mulching film in pepper fields production,and screen suitable biodegradable mulching film products,this study compared the application effects of 3 different components of full-biodegradable mulching film,including tarch-base,PBAT+PLA,PBAT+PLA+PHA in pepper fields production.The results showed that 2 black full-biodegradable mulch BM2 and BM3 with PBAT as their main ingredient could all have accelerating effects on pepper plant height,spread width,stem thickness,and root system dry weight.Moreover,all of them could significantly increase pepper yield.The increasing rates were 67.8%and 72.7%,respectively comparing with those of the CK.The degradation law of these 2 kinds mulch film were applicable to pepper fields production,and the residual film would not affect the plowing operation of farm machinery after closing the garden.During spring pepper fields production the black full-biodegradable mulch film with PBAT as its main component could be used at Wuhan area.
