基于层次分析法的贵州省油菜生产技术应用评价研究

Study on Application and Evaluation of Rapeseed Production Techniques in Guizhou Based on Analytic Hierarchy Process(AHP)

[目的]为贵州省油菜生产的进一步发展提供科学依据。[方法]应用层次分析法(AHP)对各因素在贵州省油菜生产中的作用进行评价。[结果]在准则层排序中,各生产技术对产量的贡献率以施肥最大,其次是品种,最后是栽培技术和病虫害综合防治,其贡献率分别为41.04%、34.29%、18.74%和5.92%。在措施层排序中,杂交品种对产量的影响最大,贡献率为27.12%,其次是氮肥16.83%和密度9.46%,常规品种7.17%、有机肥6.61%、磷肥6.58%、钾肥5.89%、播期4.18%、硼肥5.13%、免耕栽培2.85%、虫害综合防治3.15%、病害综合防治2.77%、育苗移栽2.25%。[结论]贵州省油菜要获高产,必须以优良品种为基础,平衡施肥为保障。

[Objective] The aim of the research was to provide scientific base for further development of rape production in Guizhou province. [Method] The actions of various factors in rape production in Guizhou province were evaluated. [Result] In the ordination of criterion hierarchy the contribution of production technology to yield was most, followed by the fertilizer, the cultural technique and the comprehensive control of plant disease and insect pests, and their contributions to yield were 41.04 %, 34.29 %,18.74 % and 5.92 %, resp. In the ordination of measure hierarchy, the contribution of hybrid variety to yield was most （27.12 %）, followed by the nitrogenous fertilizer （16.83 %）, the density （9.46 %）, the conventional variety （ 7.17 %）, the organic manure （6.61%）, the phosphate fertilizer （6.58 %）, the potassium fertilizer （5.89 %）, the broadcasts time （4.18 %）, the boric fertilizer （5.13 %）, no-tillage cultivation cultivates （2.85 %）, the comprehensive control of insect pests （3.15 %）, the comprehensive control of plant disease （2.77 %） and seedlings transplants （2.25 %）. [Conclusion] In order to obtaine the high yield of rape in Guizhou province the the improved varieties must be taken as the foundation and the balance fertilization must be taken as the ~uarantee.
