对小麦条锈病预测,一般采用经验测报法,即根据越冬菌量,春季温湿度的综合分析推测小麦条锈病的发生。农科院贾中和同志对伊力地区小麦条锈病预测曾采用越冬菌量和春季综合积分指数作自变量的回归数学方程作预测。阿克苏郭建藩同志对阿克苏地区小麦病曾采用真值图法作预测。小麦条锈病的各年发生发展,凝聚和综合反映了品种抗病性和气候越冬菌量、管理水平等的综合影响,也就是病害在时间序列上的变化是随着各个环境因子综合变化影响而产生的。马 Wheat stripe rust prediction, the general use of empirical detection method, that is based on the amount of overwintering, the temperature and humidity in spring comprehensive analysis speculated that the occurrence of stripe rust in wheat. Agricultural Science Academy Comrade Jia Zhonghe predicted the stripe rust of wheat in Yili area by using the regression mathematical equation with overwintering bacteria amount and spring integrated integral index as independent variable. Aksu Guo Jianfan comrades used the truth map method to forecast the wheat disease in Aksu area. The development of wheat stripe rust occurred each year, and the cohesion and comprehensive reflection of the combined effects of disease resistance and climate overwintering bacteria quantity and management level, that is, the change of diseases in the time series is with the comprehensive changes of various environmental factors produced. horse
