| 摘要: |
| 制备微生物培养基研究地膜的降解过程，结果表明，加混合孢子悬液的降解膜降解率比未加的提高0.58％～0.82％，加土壤悬液的降解膜降解率比未加的分别提高1％左右，不同培养基比较，降解膜降解率的大小顺序为细菌培养基＞放线菌培养基＞真菌培养基，加大田土悬液的降解膜降解率最大，降解膜的降解率远高于普通膜，提高3％～5％，用液体培养法做检验试验的结果表明，混和菌有助于降解膜的降解，液体培养中降解膜的降解率大于固体培养，提高2％左右。 |

| Effect of micro-organism on the process of biodegradable film's degradation |

| Abstract: |
| Micro-organism culture was carried out to study the process of film's degradation.The results showed that the rate of the biodegradable film's degradation added with fungi suspension was increased by 0.58%-0.82% more than that of the biodegradable film without fungi suspension.The rate of the biodegradable film added with soil suspension was increased by about 1% more than the biodegradable film without soil suspension.Compared different culture mediums,the order of rates of the biodegradable film's degradation was:bacteria medium>actinomyces medium>fungi medium.The rate of the biodegradable film's degradation with field soil suspension was the highest one.The rate of biodegradable film degradation was higher than plastic film,increased by 3%-5%.The results of test under liquid culture were that mixed bacterium were helpful to biodegradable film's degradation;the rate of biodegradable film's degradation under liquid culture was higher than that of solid culture,increased by about 2%. |
