摘要:

为研究楚雄烟区烤烟新品种‘NC297’的配套栽培措施,确定楚雄烟区烤烟‘NC297’适宜的种植密度和留叶数,设计3个水平的种植密度和留叶数的正交试验。试验结果表明,密度13800株/hm2,留叶18片处理有最大的株高、叶长、叶宽。黑胫病、青枯病、气候斑、普通花叶病病情指数在中低密度处理下显著低于高密度的对照组。低密度处理净光合速率、CO2浓度、气孔导度、蒸腾速率均处于较高水平。种植密度15100株/hm2、留叶数20片外观质量表现最佳,密度13800株/hm2、留叶18片处理次之。密度13800株/hm2、留叶18片/株的处理均价和中上等烟比例显著最高,产量较高,产值仅次于种植密度16600株/hm2、留叶18片/株的处理。密度13800株/hm2、留叶18片/株的处理烟叶化学成分最协调,总分最高。综合本试验结果来看,烤烟‘NC297’在楚雄烟区的适宜种植密度为13800株/hm2,适宜的打顶留叶数为18片/株。

Abstract:

In order to study the supporting cultivation measures of the new flue-cured tobacco variety ‘NC297’ in Chuxiong tobacco-growing area, and determine the suitable planting density and number of leaves left, the orthogonal test with three levels of planting density and number of leaves left of flue-cured tobacco ‘NC297’ was designed. The results showed that the density of 13800 plants/hm2 and 18 leaves per plant had the largest plant height, leaf length and leaf width. The disease index of black shank, bacterial wilt, climate spot and common mosaic disease were significantly lower in the medium to low density treatment group than in the high-density control group. Net photosynthetic rate, CO2 concentration, stomatal conductance and transpiration rate of low density treatment all were at a high level. The planting density of 15100 plants/hm2 and 20 leaves per plant showed the best appearance quality, followed by the treatment with the density of 13800 plants/hm2 and 18 leaves per plant. The density of 13800 plants/hm2 and 18 leaves per plant treatment had significantly higher average prices and the highest proportion of medium to high quality tobacco, and high yield. The output value was only second to the treatment with planting density of 16600 plants/hm2 and 18 leaves per plant. The treatment with a density of 13800 plants/hm2 and 18 leaves had the most coordinated chemical composition and the highest total score. According to the results of this experiment, the suitable planting density of flue-cured tobacco ‘NC297’ in Chuxiong tobacco area is 13800 plants/hm2, and the suitable number of leaves left for topping is 18 per plant.
