| Abstract: |
| To ensure the effect of biodegradable film mulching(BFM)on soil microorganisms, which limits the application of BFM in agriculture. In 2018, the conducted a field experiment in Fuxin and Haicheng(Liaoning Province, China)to test five different treatments:clear and black biodegradable film mulching, clear and black traditional plastic film mulching, and no mulching. The soil respiration rate, hydrolytic enzyme activity, microbial biomass, and phospholipid fatty acid(PLFA)levels were measured in the spring and autumn of 2019. The results showed that short-term plastic film mulching had no effect on soil dissolved organic carbon, enzyme activity, microbial biomass, or PLFA. However, the soil respiration rate was higher under BFM than under traditional plastic film mulching at both sites, suggesting that BFM could enhance soil microbial activity. The long-term effects of biodegradable film mulching on soil microorganisms were desirable, but short-term biodegradable film mulching did not negatively impact soil microorganisms. |
