稻纵卷叶螟是水稻的主要害虫之一,本地一年发生4—5代,以二代发蛾量较大。过去由于二代稻纵卷叶螟发生量的预报方法不够准确,影响了指导大面积的防治工作。为了寻找较切合本地区二代发生量的预报办法,笔者根据本地区1976年以来的测报资料和气象资料,找出影响稻纵卷叶螟二代发生量的主导因素(温雨系数与蛾初见期)。试图用回归分析法来探讨二代稻纵卷叶螟的发生量的预测。
Rice leaf roller is one of the main pests of rice, the local occurrence of 4-5 generations a year, the second generation of hair moths larger. In the past due to the second generation of rice leaf roller occurred in the forecast method is not accurate enough, affecting the guidance of a large area of prevention and control work. In order to find out the forecasting methods which are more suitable for the occurrence of the second generation in this area, the author finds out the dominant factors that affect the occurrence of the second generation of the rice leaf roller based on the measured data and meteorological data since 1976 See period). Try to use regression analysis to predict the occurrence of the second generation rice leaf roller.
