| 摘 要： | 本研究利用经典的聚集度指标法和回归分析法对该病害的空间分布型进行测定,探明猕猴桃溃疡病的田间分布情况。结果表明,猕猴桃溃疡病病株在大田呈聚集分布,分布的基本形式为个体群。分别计算了猕猴桃溃疡病大田抽样的最适理论抽样数和序贯抽样数,确定了该病害抽样的最佳样方大小,通过上述研究有效提高调查抽样的效率,为提高该病害田间调查的准确性和制定有效的防治措施提供依据。

| Abstract: | In order to find out the distribution of kiwifruit canker disease in the field,the spatial distribution pattern of the disease was determined by classical aggregation index method and regression analysis method in this study.The results showed that canker-diseased kiwifruit plants showed aggregation distribution in the field,and the basic form of distribution was individual population.The optimum theoretical and sequential sampling numbers were calculated respectively for field sampling of Kiwifruit canker disease,and the optimum sampling square size was determined.The efficiency of investigation sampling was effectively improved through the above research courses,thus providing reference for the prevention of this disense. |
