| 摘 要： | 2009年对雪茄外包皮烟不同生育期干物质和矿质营养元素含量进行了测试分析。结果表明：在浙江省桐乡市烟苗移栽后30 d内,各器官生长均较慢,矿质元素含量低；移栽30 d以后,根、茎、叶生长均逐渐加快,此段时间正值烟株干物质积累和矿质营养元素吸收的高峰期,是雪茄外包皮烟产质量形成的重要时期；移栽50 d以后,烟株各器官生长速度明显放慢,矿质营养元素的含量也有所降低；但始终以叶片为分配中心。因此,在雪茄外包皮烟生长前期应当重施基肥、早施追肥,以适应烟株生长的需要,在生长后期,烟株各部分对矿质营养元素的吸收能力降低,总含量也降低,这时可进行根外追肥,以提高烟叶的品质。

| Abstract: | The content of dry matter and mineral nutrients of cigar wrapper tobaccos was analyzed in different growth periods in 2009.The results showed that all organs grew slowly and the content of mineral nutrients was low in 30 d after transplanting in Tongxiang,Zhejiang Province.After 30 d,all organs grew faster and the accumulation speed of dry matter and mineral nutrients were fastest in this period,which was very important period for the yield and quality of the cigar wrapper tobacco.After 50 d,every organ gre... |
