| 摘 要： | 应用灰色系统理论，对纳罗克非洲狗尾草的株高、发芽势、发芽率、千粒质量、种子产量等指标进行灰色关联分析，建立了施肥、刈割、生长调节剂处理组合的综合评估模型，并对其综合处理效果进行了评估。结果表明：组合A1B3C1（氯丁唑600mg／L＋施氮75kg／hm^2＋1年刈割2次）在评估中得分最高，综合处理效果最好，该模式可作为云南省纳罗克非洲狗尾草种子生产的田间栽培模式进行推广。

| Abstract: | The effect of synthetic treatment combinations of nitrogen application,cutting frequency and growth regulator application on Setaria sphacelata cv.Narok was evaluated by using a comprehensive evaluation model based on grey system theory with five main indexes,including plant height,germination vigor,germination rate,thousand seed weight and seed yield.The result indicated that the combination A1B3C1(paclobutrazol 600 mg/L + 75 kgN/hm2+ cutting twice annually) was the best and could extended in Yunnan Provin... |
