大豆灰斑病从1981年以来逐年加重,影响大豆产量和品质的提高。本文研究了灰斑病菌的生物学特性,初步结果病菌孢子萌发适宜温度21℃—26℃;病菌孢子在水滴中萌发快,温度24℃时两小时萌发率可达37.9%;菌丝生长适温21℃—26℃。当最低温度12℃以上,日平均温17℃以上或日平均温度35℃以下病菌方能产生孢子。病菌孢子在温度20℃—22℃时生命力为7天。

According to the inoculative experiments in green house,the results showed that the latent period of soybean frogeye leaf spot was determined by the effective accumulative temperature for certain cultivars. The dynamic variation of daily rate of lesion appearance can be forecasted by the effective accumulative temperature. The paper showed that the relationship between the accumulative daily rate of lesion appearance and effective accumulative temperature of 3 cultivars might be described Gompertz model....

The paper showed that the relationship between the accumulative daily rate of lesion appearance and effective accumulative temperature of 3 cultivars might be described Gompertz model. The model of 3 cultivars are:

通过人工接种试验证明,在品种和小种组合一定时,大豆灰斑病的潜育期主要是由温度决定的,利用有效积温可以预测潜育期的动态变化。本文供试3个品种的日显证率与有效积温的关系可以用Gompertz模型描述,并获得了3个品种的显症率预测式。

By field inoculation to simulate the natural occurrence of frogeye leaf-spot of soybean in order to get plots with different disease severity theinfluence of each class of disease severity on yield,abortive pod rate and weight of 100 seeds were assessed. The result show that severity of class 2 induced obvious yield loss. Three optimized models for the influence of different class of severity in various growth stages were established by binary polynomial stepwise regression analysis with growth stage and severity...

By field inoculation to simulate the natural occurrence of frogeye leaf-spot of soybean in order to get plots with different disease severity theinfluence of each class of disease severity on yield,abortive pod rate and weight of 100 seeds were assessed. The result show that severity of class 2 induced obvious yield loss. Three optimized models for the influence of different class of severity in various growth stages were established by binary polynomial stepwise regression analysis with growth stage and severity class as independant variables and yield, abortive pod rate and weight of 100 seeds as dependent rariables. The models of population yield loss due to infection of soybean frogeye leaf spot were also established by the same way. By analysis of correlation it was shown that the seed beginning stage was the critical growth stage for yield loss assessment, the disease severity of that stage caused the greatest yield loss. Two models for critical point were developed.

通过在田间进行人工接种模拟自然发病流行的情况,确定大豆灰斑病发病为2级时是引起大豆减产的病情低限。采用二元多项式逐步回归法,建立了生育期(生长发育天数)和病级单独及联合起来对单株产量、瘪荚率和百粒重影响的优化方程,同时建立了灰斑病对大豆田间群体产量损失估计模型。并且通过相关性分析,确定始粒期病情对大豆产量影响最大,建立了关键点模型
