| Abstract: | In this paper the quantitative research on some main subsystems of epidemic of the rice leaf blast were studied using the principle of the system anylisis and the method of botanical epidemiology.Thus,4 submodels--"Index of the promoting disease by temperature humidity and rain","potentiality of incubation and symptom appearance" are built.The basis is the established to set up simulation model of epidemic of rice leaf blast in the field. |
