摘要
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。
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 afterwards decreased. Under the planting density of 16 500 plants/ hm2, chemical composition of flue-cured tobacco leaf harmonized better. By synthesize analysis, planting density of 13 500 plants/hm2could be most beneficial to the target of good quality and proper yield under the test condition.
