摘　　要：为了明确不同颜色全生物可降解地膜对湖北省高山地区辣椒(Capsicum frutescens L.)生长发育的影响,采用田间试验,以不覆膜、白色和黑色聚乙烯地膜为对照,分析了白色和黑色全生物降解地膜的增温作用、降解性能和辣椒产量。结果表明,辣椒生育前期(覆膜后12~33 d)是地膜增温的主要时期,覆膜种植主要提高该时期5 cm土层土壤温度;全生物降解地膜增温效果与聚乙烯地膜相近,白色地膜增温效果优于黑色地膜;全生物降解地膜诱导期在40~54 d,白色地膜降解速度比黑色地膜快,不利于抑制杂草生长;全生物降解地膜未改变辣椒产量高峰期,主要提高第5~8次采摘期辣椒产量。综合考虑保温、抑制杂草、产量等因素,湖北省高山辣椒露天栽培推荐使用厚度为0.01 mm,主要成分为PBAT、PLA的黑色全生物降解地膜。In order to clarify the influence of biodegradable film with different colors on the growth and development of pepper(Capsi-cum frutescens L.)in the alpine region of Hubei Province,field experiments were conducted to analyze the warming effect,degradation performance and pepper yield of white and black fully biodegradable film by setting up no film,white polyethylene film and black poly-ethylene film as controls.The results showed that the early growth stage of pepper(12~33 d after film mulching)was the main period of warming,and the film mulching mainly increased the temperature of the 5 cm soil layer during this period.The warming effect of ful-ly biodegradable film was similar to that of polyethylene film,and the warming effect of white film was better than that of black film.The induction period of fully biodegradable film was 40~54 d,and the degradation rate of white biodegradable film was faster than that of black biodegradable film,which was not conducive to inhibiting the growth of weeds.Fully biodegradable film did not change the peak of pepper production,mainly increasing the yield of pepper from the 5th to 8th picking period.Considering factors such as insula-tion,weed suppression and yield,it was recommended to use 0.01 mm black fully biodegradable film made of PBAT and PLA for pep-per cultivation in the alpine region of Hubei Province.
