摘要
为获得‘云烟87’最佳农艺性状、经济性状及烟叶品质,采用三因素二次饱和D-最优设计,研究施肥量、密度、单株留叶数等对‘云烟87’田间生长、经济性状及烟叶品质的影响。结果表明:施肥量和密度对‘云烟87’生育进程有一定的影响,当单株施肥量最多(88.9 g/株)、密度最小(1 000株/667m2)时,烟株提前进入团棵期,烟叶成熟期变慢,大田生育期延迟;施肥量和密度对烟株的株高、茎围、出叶数、最大叶长、叶宽等农艺性状和产量、产值、均价等经济性状影响较大,其中种植密度是影响产值的首要因素,其次是施肥量(纯氮),作用最小的是留叶数。该结论为‘云烟87’在威宁烟区的栽培技术优化提供参考。
In order to get the best agronomic characters, economic characters and tobacco leaf quality of’Yunyan-87’, the effects of fertilizer application rate, density and leaf number per plant on field growth, economic characters and tobacco leaf quality of ’Yunyan 87’ were studied by using three-factor quadratic saturation D-optimal design.The results showed that in the growth process,the amount and density of fertilizer had a certain effect on the growth process of flue-cured tobacco. When the amount of fertilizer applied per plant(88.9 g/plant) was the highest and the density was the smallest(1 000 plants/667 m2), the tobacco plant entered the rosette stage in advance, the mature stage of tobacco leaves became slower and the growth period of field was delayed.In terms of agronomic characters: the amount and density of fertilizer had great effects on the agronomic traits such as plant height, stem circumference, leaf number, maximum leaf length, leaf width and so on. In terms of economic characters: the amount of fertilizer, density and number of leaves had significant effects on the yield, output value and average price of ’Yunyan 87’, among which planting density was the primary factor affecting the output value, followed by the amount of fertilizer(pure nitrogen), and the smallest effect was the number of leaves left.This paper provided reference for the optimization of cultivation technology of ’Yunyan-87’ in Weining zone.
