【摘要】 通过对水稻自然发病情况连续 3a的调查 ,获得了 95组水稻穗颈瘟普通率和严重度间对应关系 (I S关系 )的数据 ,通过对这些数据的分析 ,发现水稻穗颈瘟的I S关系可用指数函数曲线y =aebx(b >0 )来描述。更多还原

【Abstract】 relevant datum of the popularity of rice blast and its damaged degree were obtained through the investigation in succession on the occurrence of rice blast. The relationship between the popularity of rice blast and its damaged degree could be described with the exponent curve: y = a e bx (b >0) through the analysis of these datum.更多还原
