摘要
研究了不同营养水平、不同移栽日期条件下烤烟(NicotianatabacumL.)品种K326的生育动态,得出了适宜的叶面积指数增长数学模型,田间最大叶面积指数以3~3.5为宜.团棵期烟株的适宜长相为:株高25~30cm,叶位15左右,绿叶数12左右,最大叶长35cm左右,叶面积指数0.4左右.圆顶后,株型以腰鼓型至筒形,腰叶长60~65cm较为适宜.
The effects of the rate
of fertilizing and the date of transplanting on the growthdynamic of plants and the quality of
cured leaf in flue-cured tobacco(Nicotiana tabacum L.)were studied during 1992 and 1993,which
showed that the suitable dynamic modle of increase in LAI(Leaf area index). The appropriate
maximum LAI was 3. 5 or so. The optimum growth feature at Tuanke stage(just before the
maximum-growth period)is as follows :the height of plant 25~30 cm.the stalk position 15.the
number of the living leaves 12,the length of the biggest leaf 35 cm, the LAI 0. 4 or so.
