聚集度指标测定、Iwao’s M~·,(?)线性回归和Taylor’s幂的法则分析结果表明:豆田龟纹瓢虫的空间分布型为聚集型,其基本成分是个体群,且聚集度随种群密度增加而升高。聚集的原因是由环境条件引起的。由于属聚集分布,用Iwao’s资料代换法求取每块田龟纹瓢虫的相应y值。根据Iwao’s抽样公式和序贯抽样公式的计算结果,为大豆蚜虫的防治提供理论依据。 The results of aggregation degree index, linear regression of Iwao’s M · ·, linear regression of Taylor’s power and Taylor’s law showed that the spatial distribution pattern of the ladybird ladybird was aggregated and its basic composition was individual, Increase and increase. The reason for the aggregation is caused by environmental conditions. Due to the aggregation distribution, Iwao’s data substitution method was used to obtain the corresponding y value of each field. According to the calculation results of Iwao’s sampling formula and sequential sampling formula, it provides a theoretical basis for the prevention and control of soybean aphid.
