摘要
为探明黔东南黄平优质烟生产最佳种植密度,分别在中上等肥力和中下等肥力地块设置4个因素水平进行试验。试验结果表明:随着植烟密度的增加,烟株茎围、单株叶面积先增后减。从烟叶产值、产量等经济性状比较来看,中下等肥力适宜种植密度为1100～1200株·667m-2,中上等肥力适宜种植密度为1000～1100株·667m-2。
To explore the best density of high-quality tobacco at Huangping county, southeast of Guizhou, experiments were done with four density at better than average and below average fertility level field. The results showed that tobacco stub caulis, leaf area reduced after rounding with increase of density. For tobacco yield and quality, the density of 1 100-1 200 stubs·667 m^-2 was fit for below average fertility level field, and 1 000-1 100 stubs·667 m^-2 for better than average fertility level field.
