单目标化局势决策在小麦品种布局中的应用

Application of Grey Situation Decision of Mono-target in Variety Distribution of Wheat

[目的]研究单目标化局势决策在小麦品种布局中的应用效果。[方法]参考2006年河南省小麦生产试验资料,采用单目标化局势决策,对新麦19号、濮麦10号、平安3号、郑麦3634、豫农201、郑农17、花培1号、周麦20号8个小麦品种的产量、冻害、倒伏和病害进行综合分析,比较其综合效果测度值。[结果]在不同生态类型区,种植豫农201均为最优品种布局,其次是周麦20、郑农17,说明豫农201在各地的适应性最好。由于单目标灰色局势决策分析考虑的因素较多,因此其结果更具科学性。[结论]采用品种灰色布局的原理与方法指导品种布局,可作出更客观合理的决策。

[ Objective] The study aimed to research the application effect of grey situation decision of mono-target in variety distribution of wheat. [ Method ] With production test data of wheat in 2006 in Henan Province as reference, the grey situation decision of mono-target was taken to comprehensively analyze the yield, freezing injury-, lodging and diseases of 8 wheat varieties such as Xinmai 19, Pumai 10, Pingan 3, Zhengmai 3634, Yunong 201, Zhengnong 17, Huapei 1 and Zhoumai 20, the measure -value on comprehensive effects of 8 wheat varieties were compared. [ Result] In different ecological districts, the optimum variety distribution was all planting Yunong 201, and the following were planting Zhoumai 20 and Zhengnong 17, which indicated that the Yunong 201 had best adaptability in each area. Because more factors were considered in the method of grey situation decision of mono-target, so the results with this method were mere scientific. [ Conclusion] U- sing the principle and method of gray arrangement could guide variety distribution, which could make out the more objective and reasonable decision.
