本文应用6个聚集度指标测定得出棉花蕾铃期棉蚜的空间分布型呈聚集型;确定了棉蚜田间取样以“Z”字型、对角线方式抽样更能正确估计棉花田间蚜量
In this paper, the spatial distribution patterns of cotton aphid in cotton boll boll stage were determined by using six clustering indexes. It was confirmed that the sampling of aphids in the field could correctly estimate the amount of aphids in cotton field with “Z” shape and diagonal sampling
