桃小食心虫(以下简称“桃小”)越冬幼虫出土始期的预测预报,是指导防治“桃小”进行“地下防治”的依据。我们在庄河英烈士乡,经过5年研究看出,“桃小”越冬幼虫出土始期与5月中旬的温雨系数(温雨系数 E=R/,R、分别为5月中旬降雨量和平均气温)关系极为密切。因此,我们用二者这种相关关系建立了回归方程式,来预测“桃小”越冬幼虫出土始期。经相关分析表明,相关极显著,证明利用这种方法预测“桃小”越冬幼虫出土始期是可能的和有希望的。
Peach mungbean worm (hereinafter referred to as “peach”) overwintering larvae unearthed the beginning of the forecast, is to guide the prevention and control “peach” for “underground control” basis. After 5 years of study, we found in the martyrs’ hometown of Zhuanghe that the warm rain coefficient (E = R /, R) between the beginning and the middle of May of “peach” overwintering larvae are the rainfall and average temperature in mid May Very close relationship. Therefore, we established the regression equation using the correlation between the two to predict the onset of “peach” overwintering larvae. The correlation analysis showed that the correlation was very significant, which proves that it is possible and promising to predict the initial stage of the “peach” overwintering larvae by this method.
