摘要
研究表明,不同农艺措施对烟叶的叶面积影响不大,顺坡种植与横坡种植相比较,烤烟各方面农艺指标都比横坡种植的差,但是后期烟叶落黄较好。秸秆处理的烤烟,移栽30 d表现出缺氮现象,烤烟移栽90 d,秸秆处理烟叶的叶绿素含量高于不施用秸秆处理的,不同部位烟叶的叶绿素含量从高到低顺序为上部>中部>下部。
Effects of different agricultural measures on tobacco leaf area was not significant, the agricultural characters of tobacco in the straight-planting were inferior to that in the cross-planting,but the tobacco had better maturity in the straight-planting. The tobacco leaf with straw mulching turned yellow at 30 days after transplanting,as tobacco had the symptom of scarce nitrogen. At 90 days after transplanting,the tobacco leaf with straw mulching had higher chlorophyll content, and the rank of leaf chlorophyll content in different part of tubaceo was that as the upper part leaf 〉 middle part leaf 〉 lower part leaf.
