| 摘要: |
| 以单个病程为基本结构,将晚疫病流行过程中各子模型有机地连接起来组建成番茄晚疫病流行系统模拟模型 SIMTLB-Ⅰ。SIMTLB-Ⅰ由 FORTRAN 77语言实现,解题时距为1 d,系统输入项包括始病期、初菌量及气象条件等。用田间实际的环境条件作为模拟的输入项进行了模拟试验,认为系统的结构基本合理,并就始病期、初菌量、相对湿度及施药措施对病害发展的影响进行了模拟试验。 |

| Abstract: |
| The epidemic process of tomato late blight(Phytophthora infestans (Mont.) de Bary.) was divided into the following sub-processes:host growth,spore deposition,spore survival,infection,incubation and lesion apparition,lesion expansion and lesion sporulation,based upon the asexual cycle of P.infestans State variables were designed to represent the major morphological stages of the tomato- P.infestans system.Systems analysis and modelling were undertaken to describe the relationships between the components of t... |
| Key words: tomato late blight Phytophthora infestans simulation model |
