【摘要】 为提高烟叶品质,对麦秆还田、稻草还田、稻草覆盖、麦秆覆盖、地膜覆盖、无覆盖进行了比较试验。结果表明:麦秆覆盖的处理上等烟比例、均价最高,地膜覆盖的处理烟叶产量、产值最高。在烟株团棵期之前,土壤温度较低,地膜覆盖保温保湿效果好,烟株生长量增加较快,但从旺长期至初采期麦秆覆盖处理的效果较好,烟株生长量增长较快,稻草覆盖处理次之。麦秆还田处理的烟叶分层落黄较早,且麦秆还田有利于改良土壤、培肥地力。更多还原

【Abstract】 In order to improve the quality of tobacco leaf,the effect of wheat and rice straw applying back to fields,straw mulch,film mulch and without mulch were compared.The results showed that the(proportion) of high grade leaves and average leaf prices in wheat straw mulch treatment and the yield and output value in film mulch treatment were the highest.Before the rosette stage,when soil temperature was relative low,the plant with film mulch grew faster due to better heat and moisture barrier ability of the film;however,during fast growing and early harvesting stages,the plant with wheat straw mulch grew faster,followed by that with rice straw mulch.The tobacco leaves with wheat straw applying yellowed earlier,moreover,wheat straw back-applying benefited soil fertility and soil improvement as well.更多还原
