摘 要: | 采用聚集度指标、Iwao法和Taylord法等对茶毛虫卵的空间分布型进行调查和分析.结果表明,茶毛虫卵在田间呈聚集分布,其聚集原因可以由环境条件引起,也可以由茶毛虫本身的习性引起.在此基础上得出其理论抽样模型为n=t2/D2 ·0.063 7(x)-0.2108.

Abstract: | The spatial distribution of Euproctis pseudoconspersa eggs were in- vestigated and analyzed by using aggre- gation index, Iwao method and Taylord method. The results showed that the spatial distribution of Euproctis pseudo- conspersa eggs in the fields belonged to the aggregafive pattern, which was caused by the environmental conditions or the behavior of Euproctis pseudocon- spersa. Based on the investigation, the sampling model was n=t2/D2 ·0.063 7(x)-0.2108. |
