| Abstract: | Abstract Through analysing the data (1974- 1991 ) of corn borer and the climatic factors in the north onegeneration-Nenjiang region of Heilongjiang provence by using statistical analysis and regression equation, thedecision model for integrated control of corn borer in a nonparticular calamity year was established. By usingin the corn field of 250000 hm2 since 1992,the correct rate of forecast was over 90% and the benefit was re-markable. |
