雪茄原料烟叶种植密度与产量·质量关系研究

The Research of the Relationship between Planting Density and Yield and Quality of the Cigar

[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 ] In order to explore the reasonable planting density of raw material of cigar in Sichuan Shifang. [ Method ] adopting two varieties including GH-1 and GH-2, the relationship between planting density conditions and yield and quality of the cigar was studied setting up four planting density treatment. [ Result] When planting density was 28 500 and 30 000 plants/hm2 , the cigar growing,yield and quality was the best. [ Conclusion] The study determineed suitable planting density in two varietie of GH-1 and GH-2, and had the very vital signifi- cance for promotion and production of cigar tobacco varieties.
