经模拟试验证明，当降解膜残片以１：１０００膜土比残留于土壤耕层时，凡小于４×４ｃｍ２的降解膜残片对土壤耕层中的毛管水、入渗水、饱和水及蒸发速度等主要水分性状无显著影响。
The results of simulation experiments show that when the degraded membrane fragments remain in the soil layer at a ratio of 1: 1000 film to soil layer, the degradable film fragments of less than 4 × 4cm2 have different effects on capillary water, infiltration water, saturated water and evaporation rate No significant effect on the main water traits.
