摘要
采用"311-A"拟饱和最优回归试验设计,针对影响辽宁朝阳烟区烤烟质量的施氮量、密度和留叶数进行了研究,通过计算机模拟了施氮量、留叶数、密度与产量、产值的关系,建立了数学模型,寻优选出了最佳方案。对于指导辽宁朝阳烟区的烟叶生产、打造朝阳烟叶的品牌奠定了理论基础。
The authors extended research on nitrogen rates, leaves of tobacco remained and density which affect quality of Liaoning Cbaoyang flue-cured tobacco by 311 -A regression design. The relationship between nitrogen rates, leaves of tobacco remained, density and output, production is simulated by computer, as well as the establishment of a mathematical model. Finally the best design is selected. The thesis establishes a theoretical foundation for＇guiding Liaoning Chaoyang tobacco leaf production, and creating Chaoyang tobacco leaf brand.
