摘要
Abstract
Dominant factors to affect occurrence and damage level of the rice leaf roller have been obtained since 2000. By analysis of the impact factors to occurrence and damage level of the rice leaf roller. Adopting the multivariate regression method, the prediction model of occurrence and damage level of the rice leaf roller was set up, which was suitable to be used in Dazhou Rice Areas. By repeated testing in the rice fields, the coincidence rate was 81.82%~90.91%, and with nice application effect from 2011 to 2012.关键词
