摘要
采用疫区和室内模拟的试验 ,研究水稻稻瘟病菌附着叶表至病痕扩展的过程 ,分别找出了病菌侵染的各主要环节 (孢子附着、侵入、潜育 -显症、病斑扩展 )与主要影响因子 (水稻生长阶段、品种抗性及气象因子等 )的数学关系 。
The infection process of Pyricularia grisea were studied quantitatively in epidemic regions and in laboratory simulations.The mathematical models for the relationships between main link of infection (conidia adhesion,invasion,latency appear,lesion expansion) and main influencing factors (rice growth stage, cultivar resistance, and meteorlogical factors) were established, respectively.
