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
The results showed that the basic components of banana bunchy tops distribution in banana plantations were very limited individuals, while the spatial distribution of the basic components was uniform distribution. The regression equations for m * -m and lgS2-lgm are respectively m * = 0.0389 + 0.7613m (r = 0.9875 **) and lgS2 = -0.181 + 0.7933lgm (r = 0.9618 **) The number of samples can be estimated from n = (1.0389 / m-0.2387) / D2. Plant protection commonly used on the diagonal method, five-point, checkerboard, Z-shaped and parallel leapfrogging methods are suitable for banana bunchy top strain field sampling. In the case of very low incidence, the use of checkerboard and parallel jump method is better
