摘要: 为了使棉花枯、黄萎病和苗期根病病情分级的国标严谨、科学、可行,以适应科研和生产的需求,本研究对中国棉花枯、黄萎病和苗期根病分级标准诞生与演变的过程进行了回顾,肯定了某些分级标准在这3 种病害研究与防治方面的贡献。指出了GB/T 17980.92—2004 和GB/T 17980.93—2004 中棉花枯、黄萎病和苗期根病分级国标的缺陷。比较了不同分级标准对病情指数统计结果的影响。依据制定植物病情分级标准的理论和国内外多种植物病害分级的实例,提出了修订棉花枯、黄萎病和苗期根病分级标准的建议。

Abstract: In order to make the national rating standards on cotton Fusarium wilt, Verticillium wilt and root rots of cotton seedling being rigorous, scientific and feasible, and meet the demand of the scientific research and production, this article reviewed the birth and development of the national rating standard on cotton Fusarium wilt, Verticillium wilt and root rots of cotton seedling, and approved the roles of some rating standards on the research and control of the three diseases. It also pointed out the defects of GB/T 17980.92—2004 and GB/T 17980.93—2004. In addition, it compared the effects of different rating standards on the statistical results of disease index. According to the theories of setting plant disease rating standards and various examples of plant disease rating home and abroad, the article provided some suggestions on how to revise the disease rating standards of cotton Fusarium wilt, Verticillium wilt and root rots of cotton seedling.
