| 摘 要： | 为提高烟叶品质,进行了对植烟土壤不同覆盖方式的比较试验,结果表明:高C/N比秸秆与地膜双覆盖能够协调烤烟生长全过程的土壤温度,并且地温日变化幅度小,蓄水保墒作用显著,有机质积累明显,腐殖化作用强,使得烟叶内在化学成分比例更协调,产值高。秸秆单覆盖对土壤性状改良与秸秆和地膜双覆盖相似,烟叶内在化学成分较协调,品质较好,但由于在烤烟生长前期不能提高土壤温度,使得烟叶生长速度较慢,产量下降,产值与地膜单覆盖差异不显著;由于没有新鲜的有机质补充,地膜单覆盖对土壤性状改良不及秸秆单覆盖和秸秆与地膜双覆盖,从而使得烟叶品质较不协调,但产量较高,产值也较高。 |

| Abstract: | In order to improve the quality of tobacco leaf,the experiment was carried out to compare effect of different mulch ways on soil character and tobacco leaf quality, the results showed that high C/N ratio straw and plastic film double mulches could harmonize soil temperature at all the stages of growth and development of flue-cured tobacco, decrease soil temperature change range, significantly increase and retain the capacity of soil moisture, accumulate more organic matter. Single high C/N ratio straw mulch was similar to straw and plastic film double mulches in soil improvement and tobacco leaf quality. Because single straw mulch decreased soil temperature at the prophase of flue-cured tobacco growth and development, growth speed was relatively slow that resulted in the decrease of yield. But the output value had no significant difference between one fold high C/N ratio straw mulch and single plastic film mulch. Due to no supply of fresh organic matter, effect of one fold plastic film mulch is inferior to that of former mulches on soil improvement, which led to the relatively poor tobacco leaf quality. However, one fold plastic film mulch increased tobacco leaf yield, the output was still higher than the one fold straw mulch and lower than the double mulches. |
