| 中文摘要: |
| 本文应用聚集度指标法、Iwao法和Taylor幂法则等方法, 测定了籼-粳杂交稻稻曲病在田间的空间分布型和抽样技术。结果表明, 稻曲病田间空间分布主要为非随机性的聚集型分布。m*-x回归分析表明, 稻曲病空间分布的基本成分是个体群, 个体间相互吸引。Taylor幂法则分析显示, 稻曲病病株聚集度依赖于密度。不同取样方法准确度比较结果指出, 稻曲病田间抽样调查宜采用平行跳跃式取样, 在此基础上提出了稻曲病田间理论抽样公式和序贯抽样表。 |
| 英文摘要: |
| Spatial distribution and sampling techniques of rice false smut (RFS) of indica/japonica hybrid rice were tested in the field by using degree of aggregation method, Iwao method and Taylor power rule. The results indicated that the spatial distribution of RFS in the field was non-random aggregation. Regression analysis of m*-x showed that the individual populations were the basal component of the spatial distribution of RFS in the field. The individual populations were mutual affinity. The analysis of Taylor power rule showed that the degree of aggregation of diseased rice plants depended on density. The comparison of accuracy rating of diverse ways of sampling indicated that sampling with parallel jumping was the best way for sampling survey of RFS in the field. The theoretical sampling formula and the table of sequential sampling of RFS in the field were presented based on the above results. |
