摘要
以鄂东南2003～2011年水稻主要病虫害危害情况为基础资料,采用马尔科夫模型对鄂东南2012年水稻主要病虫害的发生情况进行了预测。结果表明,预测2012年鄂东南各种病虫害发生等级如下:稻瘟病,4级;二化螟,4级;稻飞虱,4级;稻纵卷叶螟4,级;纹枯病4,级;蓟马3,级。
With main disease and pests of rice in southeast of Hubei Province during 2003-2011 as basic data,the occurrence of main diseases and pests in 2012 was predicted by using Markov model.The predicted grade was as follows： rice blast,fourth grade;rice stem borer,fourth grade;rice planthopper,fourth grade;rice leaf roller,fourth grade;banded sclerotial blight,fourth grade;thrips,third grade.
