摘要 对不同成熟度、施肥量、留叶数处理的烟叶组织结构、比叶重进行研究,结果表明:烟叶的厚度、栅栏组织和海绵组织厚度以完熟叶】初熟叶】过熟叶,并随施肥量增加而变厚。成熟度提高,上二棚叶比叶重下降;施肥量与腰叶比叶重负相关,与上二棚叶比叶重正相关。留叶数增多.上二棚叶厚度交薄,腰叶和上二棚叶比叶重均降低。 The result showed that tobacco leaves,palisade tissues and spongy tissues were the thickest in mellow leaves,thicker in unripe leaves,and thinner in overmature leaves,They grew thicker with fertilizer applied increasing.The specific leaf weight of second leaves was reduced with the maturity increasing.The level of fertilizer applied was negtively correlated with the specific leaf weight of cutters leaves and significantly positively correlated with the specific leaf weight of sec- ond leaves.The second leaves grew thinner and the specific leaf weight was reduced with the num- ber of leaves harvested increasing.
