小麦赤霉病是影响小麦生产的重要病害之一,特别是在沿江滨湖地区常年严重发生,一般减产四至五成。关于小麦赤霉病的流行规律和长期预测预报的研究,已有很多报道,目前在方法上多使用概率统计学建模,对预报对象进行精确的定量分析。但实际上由于病害流行程度没有截然划分的指标,所以难以达到真正确切而又恰如其分的数量描述。模糊数学却能为人们从一类大 Wheat scab is one of the most important diseases affecting wheat production, especially in the perennial rivers and lakes and lakes and lakes. There are many reports about the prevailing laws and long-term forecasting and forecasting of wheat head blight. At present, many methods are used to model the forecasting objects accurately and quantitatively. In practice, however, it is difficult to achieve a truly accurate and appropriately quantitative description of the disease because there is no clear indication of the prevalence of the disease. Fuzzy mathematics can be a big class for people
