以大蒜为试材，研究了4种不同降解地膜的物理性能和降解特性，并测定了蒜头产量和生物产量。结果表明，4种生物降解地膜物理性能和降解期存在显著差异，这些差异对大蒜的生物产量和蒜头产量有显著影响。SND1、SND2两种地膜降解速度较快，降解期不能满足大蒜的需要，大蒜产量比对照低。SND3尽管在大蒜收获前未出现明显降解，但透光率较低、雾度较高，其产量比对照显著降低；S N D4在大蒜收获前未出现明显降解，且透光率和雾度与对照接近，产量略高于对照，表明选择功能期满足需要、透光率和雾度适宜的降解地膜，可以实现降解与功能的同步，不仅利于增产，而且可通过降解减少对环境的不良影响。

Using garlic as material,the physical and degradation characteristics of 4 kinds of biodegrada-ble plastic films were studied.And the yield and biomass of garlic were measured.The results showed that there were significant differences in the physical and degradation characteristics of 4 kinds of biodegradable plastic films,which affected the garlic yield and biomass significantly.The degradation of SND1 and SND2 were faster,which couldn’t meet the need of garlic,and the garlic yield and biomass were lower than those of control.Although SND3 had no visible degradation before harvest,the garlic yield and biomass were signifi-cantly lower than those of control mainly because of the lower light transmittance and higher haze.With no vis-ible degradation before harvest and approximate light transmittance and haze with control,the yield and bio-mass of SND4 were slightly higher than those of control.In conclusion,the biodegradation film with suitable physical and degradation characteristics,which could achieve degradation and function synchronously,could not only increase the garlic yield,but also decrease the bad effects on environment.
