| 摘 要： | 通过3年试验,研究生物降解膜降解、增温保墒性能及全覆盖双垄沟播玉米苗期0~25 cm土壤温度动态和对玉米生长发育进程的影响,明确生物降解膜在生产中对普通农用地膜的可替代性。结果表明,生物降解地膜埋入土壤约30 d左右可以观测到降解效果,40 d以后开始快速降解,到80~90 d时降解可达到85%~95%,种植地膜玉米后,压入土壤或地膜上有土覆盖的部分同样有明显的降解效果,而垄上的地膜在玉米收后绝大部分仍与常规膜一样保持完好;生物降解膜保墒性能达普通农用地膜的90.4%~95.4%;作物生育前期0~25 cm土层08∶30、14∶30和20∶30平均温度比普通农用地膜低0.85℃,比露地高1.91℃;生物降解膜全覆盖双垄沟播玉米比裸地平作出苗提前5~9 d,成熟期提前11~12 d。生物降解地膜具有一定的增温、保墒作用,降低生产成本后,可在一定程度上替代不能降解的普通农用地膜。
