摘要
全生物降解地膜的替代应用是解决土壤白色污染的有效途径,在农业生产中得到越来越广泛的应用。为进一步探究全生物降解地膜在田间的应用效果,本研究评估了广东梅州全生物降解地膜的田间适用性及其对土壤环境的影响。结果表明,全生物降解地膜在梅州烤烟种植区具有良好的降解特性,覆盖32天后开始裂解,120天内降解率达72.2%。尽管全生物降解地膜保温性能略低于传统PE地膜,但基本满足烤烟生长需求,对产量和质量未产生显著影响。然而,全生物降解地膜较长的降解周期可能影响土壤后续利用,需进一步优化其降解速率。本研究为全生物降解地膜的推广应用提供了科学依据和实践参考。
The alternative application of fully biodegradable film is an effective way to solve the white pollution of soil,and it is increasingly widely used in agricultural.In order to further investigate the application effect of fully biodegradable film in the field,this study evaluated the field applicability of fully biodegradable film in Meizhou,Guangdong and its impact on soil environment.The results showed that the fully biodegradable film had good degradation characteristics in the flue-cured tobacco area of Meizhou,and began to crack after 32 days of covering,with a degradation rate of 72.2%within 12 days.Although the heat preservation performance of fully biodegradable film was slightly lower than that of traditional PE film,it basically met the growth requirements of flue-c tobacco,and had no significant effect on yield and quality.However,the longer degradation cycle of fully biodegradable film may affect the subsequent utilization of soil,and is necessary to further optimize its degradation rate.This study provides scientific basis and practical reference for the promotion and application of fully biodegradable film.
