[目的]探索四川什邡烟区雪茄原料烟叶合理的种植密度。[方法]采用“什烟二号”(GH-1)、“什烟三号”(GH-2)2个品种,设置4种种植密度,研究种植密度对雪茄烟长势、产量和质量的影响。[结果]种植密度在28500和30 000株/hm~2时,烟株的长势、产量和质量更好。[结论]确定了“什烟二号”(GH-1)和“什烟三号”(GH-2)2个品种的适宜种植密度,对于以后品种的推广和雪茄烟叶的生产都具有十分重要的意义。
[Objective] The research aimed to explore the reasonable planting density of cigar raw material in Shifang tobacco-growing area in Sichuan. [Method] With two varieties of “GH-1” and “GH-2”, four planting densities were set up to study the effect of planting density on the growth of cigar, the yield And the quality impact. [Result] When the planting density was 28500 and 30 000 plants / hm ~ 2, the growth, yield and quality of tobacco plants were better. [Conclusion] The suitable planting densities of two varieties “GH-1” and “GH-2” were determined, and the promotion of later varieties and the production of cigar tobacco All have very important meanings.
