摘要
采用灰色关联度分析方法,对10个外引菜用大豆新品系在云南省昆明夏播条件下研究其11个主要农艺性状对鲜荚产量的影响及各农艺性状之间的相互关系,得出对云南省菜用大豆鲜荚产量影响最大的因子是生物产量,而影响生物产量的主要因子是主茎节数、株高、单株荚数和出苗至开花日数。提出通过品种引育、布局,改进栽培技术等措施以促进云南菜用大豆生产的发展。
The grey system theory was employed to study the effect of 12 importent agrionmic traits on fresh pod yield and the relationship among the trait adopted in the study. The results showed that the most important limited factor for vegetable soybean production in Yunnan is biomass, which influenced by nodes per main stem, plant height, pods per plant and the duration from sowing to flowering. We suggest that the yield would be improved greatly by means of breeding and cultivating methods, such as introducing or selecting vigorous varieties with taller plant, more nodes, pods and longer growth period, promoting biomass via increasing plant density and adapted fertilizer, and improving cultivar distribution.
