腐食酪螨在平菇种植场的空间分布型及抽样技术分析

Spatial Distribution Pattern And Sampling Technique Analysis Of Tyrophagus Fulva In Pleurotus Ostreatus Plantation

对广西南宁平菇种植场危害平菇的腐食酪螨的空间分布情况进行调研,对不同的抽样技术进行对比,以Iwao回归线性方程、Taylor回归线性方程以及聚集指标来确定腐食酪螨的空间分布型为聚集分布。抽样技术的对比可以得出"对角线"和"平行线式"是菇场中较为理想的抽样方式。

The spatial distribution of tyrophagus fulvata in The oyster mushroom plantation in Nanning,Guangxi was investigated,and different sampling techniques were compared to determine the spatial distribu⁃tion pattern of tyrophagus fulvata as the aggregation distribution using Iwao regression linear equation,Taylor regression linear equation and aggregation index.A comparison of sampling techniques suggests that"diago⁃nal"and"parallel"are the preferred methods of picking mushrooms.
