摘要
应用扩散型指标,Taylor幂法则和lwao m——x回归分析法,分析了东方钝绥螨在柑桔园的分布型。结果表明,东方钝绥螨在柑桔园呈聚集分布。其最适抽样数N=7.34+31.357 5 x^(1/2),利用该螨释放防治叶螨的序贯抽样的上下限T_0(N)=4.2276N±6.3663 N^(1/2) .
The paper dealed with distribution pattern of Amblyseius orientalis Ehara in thecitrus orchard. Used expansion pattern target, Taylor power law and lwao m-? regressionanalysis. The results indicated that distribution pattern of Amblyseius orientalis Ehara wasassembled. Its best number of sampling was N=7.34+31.357 5/x. The sequential sam-pling equations of refusing and accepting that released Amblyseius orientalis Ehara to controlspider mites was T。(N)=4.2276N±6.3663 N^(1/2).
