摘要
研究提出了在桃麦间作条件下对小麦进行分区研究的方法,并以间作小麦的产量以及产量构成因素作为分区指标,利用有序样的聚类方法,根据距离桃树远近不同,将小麦种植区划分为冠下区G1、近冠区G2和近冠区G3。
This study proposes a method for partition of wheat under condition of peach--wheat intercropping, and intercrop- ping wheat yield and yield components as a zoning index, using clustering method of ordered samples, according to the distance from peach tree, divided wheat planting area into crown area G1, near the crown area G2 and near the crown area G3. Key words: wheat; intercropping; cluster analysis
