摘要
通过不同生物降解农膜对烤烟产、质量的影响研究,其结果表明:降解膜Ⅰ型比聚乙烯膜(CK)的增温保湿性能好;降解膜Ⅰ型的烟株株高、节间距、茎叶干重、单株干物重的值最高;叶面积指数和干物重的相关性以降解膜Ⅰ型、Ⅱ型达极显著、聚乙烯膜(CK)达显著;单叶重、烟叶产量均以降解膜Ⅰ型的值最高,比聚乙烯膜增产率达6.9%;降解膜Ⅰ型的降解历程达109d,与烟叶生长发育是同步的,有利于烟叶的成熟;降解膜的迅速降解减轻了对土壤和生态环境的污染,并达到优质适产的目的,为生产上广泛推广应用降解膜Ⅰ型提供了理论依据和技术措施。
By the study on biological decomposing agricultural film on yield and quality of flue-cured tobacoo, it showed that decomposing agricultural film I had a positive effect on increasing temperature and keeping humidity, and there fore, can increase the yield and upgrade the quality of flue-cured tobacco. The biological decomposing agriculal film I takces 109 days to decompose, which is the same as the growth and development of the leaf.
