摘要
应用判别分析法对 1 981～ 1 995年广东化州市早稻穗瘟的流行程度进行了分析 ,建立了早稻穗瘟流行程度的判别函数。经检验 ,判别效果显著 ,而且历史符合率达93 .3 % ,1 996～ 2 0 0 0年的预报准确率达 80 %。
By applying discriminatory analysis method,the epidemic degree data of neck blast on early rice in Huazhou city,Guangdong province during 1981～1995 were analyzed,a discriminatory function of the epidemic degree of this disease was established.The verification results showed that the discriminatory function had significant effect,its historical coincidence rate in the period from 1981 to 1995 was 93.3%,and the forecast accuracy in the period from 1996 to 2000 reached 80%.\;
