摘　　要：为缓解地膜带来的“白色污染”问题和明确生物降解膜在干旱地区玉米生产中能否代替普通地膜,比较了覆盖生物降解膜和普通地膜玉米的农艺性状和产量,进行了相关性分析。结果表明,生物降解膜覆盖的玉米株高、穗位高和穗长略低于普通地膜,差异不显著,秃尖长高于稍高于普通地膜;穗粒数、百粒重和产量低于普通地膜,减产1.40%,相对于普通地膜“白色污染”的严重性,生物降解膜的减产程度基本可忽略不计,由于其可自身降解,有效减少农田残留,可以代替普通地膜用于干旱地区玉米生产。产量与穗长、穗粗、行粒数和百粒重呈显著正相关。In order to alleviate plastic film‘white pollution’problem,and to determine whether biodegradable film can replace common plas⁃tic film in maize production in arid areas or not,we compared the agronomic characters and yield of maize covered with biodegradable film and common plastic film,and the correlation analysis was carried out.The results showed that the plant height,ear height and ear length of maize covered by biodegradable film were slightly lower than those of common film,the bare tip length was slightly higher than of common film,grain number per ear,100⁃grain weight and yield were all lower than those of common film.Compared with the serious‘white pollution’of common film,the yield reduction of biodegradable film was negligible.Because it could degrade in soil and effectively reduce farmland residues,so bio⁃degradable film could replace common film in maize production in arid areas.Yield was positively correlated with ear length,ear width,number of grains and 100⁃grain weight.
