花椰菜病害数值诊断法的研究

Research on Quantitative Diagnostics of Cauliflower Disease

对花椰菜常见病害进行总结、归类,运用模糊数学原理和灰色系统理论,将病害症状信息量化为诊断指数,然后在诊断中用模糊识别法进行比较鉴别,经简单加减运算求和,以和值最大者为诊断结论。经回顾性验证、考核性验证以及双盲试验,证明此方法简单易行,且准确率高达99%,便于推广和应用。

The common diseases were summarized and sort out,through using fuzzy mathematics principle and gray system theory,making the amount of information into diagnosis index.The diagnosis indexes were then compared and indentified through fuzzy recognition and summed through simple addition and subtraction.The maximal sum was considered as the diagnosis result.After retrospective validation,exam validation and double-blind trial,the results showed that this method could provide detailed information with high accuracy simply and quickly,and would be applied widely for extension and application,and the accuracy rate of 99%.
