摘要
在烟草移载期,将光降解膜复盖于烟垅后,50天左右始见裂纹,继而破碎粉化,经124天融合于土壤中,可避免由常规膜对烟田环境所引起的污染。同时,应用该膜后,烟草大田生育期较对照缩短14天;每公顷烤烟产量增加577.5kg;上中等烟比例提高4.2%,与使用常规膜具有同等效果。
It was proved in this study that the photodegraded plastic film increased tobacco-leaf yield and improved its quality when used in tobacco field at the planting time. The degradation of PPF stasted about 50 days later in the field and completed within 124 days, which is beneficial for deeping clean ecological environment of tobacco fields.
