不同种植密度对烤烟K326产量和品质的影响
以烤烟品种K326为试验材料,研究4种种植密度(13 500、15 000、16 500和18 000株/hm2)对烤烟农艺性状、经济性状和化学成分的影响。结果表明,随种植密度的增加,烟株株高增加,最大叶长宽和平均叶重显著降低;烤烟产量、产值和均价呈先升后降趋势;当种植密度为16 500株/hm2时,烟叶内在化学成分协调性较好;综合分析认为,试验条件下K326的种植密度为13 500株/hm2对达到烤烟优质适产目标最为有利。...

Institute of Agricultural Resource & Environment, Yunnan Academy of Agricultural Sciences, Yunnan Kunming 650205, China) The effects of four planting densities (13 500, 15 000, 16 500 and 18 000 plants/hm2) on agronomic characters, economic characters and chemical compositions of flue-cured tobacco K326 were studied. The results showed that with the increase of planting densities of flue-cured tobacco K326, the stem length gradually increased, the max-leaf length width and average weight of leaves decereased significantly, and the yield, production value and average price increased first and |
