| 摘 要： | ５种聚集度指标测定和Ｔａｙｌｏｒ、Ｉｗａｏ法检验结果表明，香蕉束顶病病株在蕉园中分布的基本成分为极有限的个体群，而基本成分的空间分布型为均匀分布．ｍ＊－ｍ和ｌｇＳ２－ｌｇｍ的回归式分别为ｍ＊＝０．０３８９＋０．７６１３ｍ（ｒ＝０．９８７５＊＊）和ｌｇＳ２＝－０．１８１＋０．７９３３ｌｇｍ（ｒ＝０．９６１８＊＊），理论抽样数可由ｎ＝（１．０３８９／ｍ－０．２３８７）／Ｄ２来估计．植物保护上常用的对角线法、五点式、棋盘式、Ｚ字型及平行跳跃式法均适于香蕉束顶病株的田间抽样．在发病率极低的情况下，采用棋盘式和平行跳跃法较佳

| Abstract: | It was found that the spatial distribution of the plants infected by banana bunchy top virus was in the well distributed pattern with considerably limited individual groups. The linear regression of m *- m and lg S 2-lg m was m *=0.038 9+0.761 3 m ( r =0.987 5 ** ) and lg S 2=-0.181+0.793 3 lg m ( r = 0.KG-4]961 8 ** ), respectively. The theoretical sampling number of field survey could be estimated by the equation n =(1.038 9/m- 0.238 9) /D 2. Routine sampling methods used in pest survey in the field including diagonal lines, five point pattern,checker board form, Z letter form and sampling at a parallel jumping rank were all suitable to the disease investigation of banana bunchy top. However, the checker board method and sampling at a parallel jumping rank were preferrable when the incidence was extremely low. |
