本文运用聚集度指数的回归分析及其改进模型等分析方法,研究了稻蓟马卷叶株在杂交稻田中的空间格局。结果表明,稻蓟马卷叶株在田间呈均匀分布。分布的基本成分是个体群(α>0),个体群的分布是均匀的(β<1)。根据空间分布信息,运用 E.Kuno(1969)的序贯抽样技术,给出了稻蓟马卷叶株的序贯抽样图和序贯抽样表。 In this paper, regression analysis of aggregation index and its improved model and other analytical methods were used to study the spatial pattern of rice thrips curl in hybrid rice fields. The results showed that the rice thistle roll leaves were evenly distributed in the field. The distribution of the basic components of the individual groups (α> 0), the distribution of individual groups is uniform (β <1). According to the spatial distribution information, using sequential sampling technique of E.Kuno (1969), a sequential sampling chart and a sequential sampling table of the rice thrips leaf roll were given.
