本文根据抗病性组份的田间实测值,组装了小麦条锈病慢锈性模拟模型——SRESM1。经初步检验认为:模拟出的流行趋势同实际情况大体相符;模型在生物学和逻辑上是合理的;各抗性组份中,侵染机率、产孢量和病斑扩展速度在慢锈流行中起主要作用,潜育期的作用其次,传染期的作用最小。通过变换初始菌量和气象条件,有助于分析慢锈品种的抗性潜力,估计其应用价值。
In this paper, based on field-measured values of the disease-resistant components, a simulation model of stripe rust of slow rust was assembled - SRESM1. Preliminary tests show that: the simulated epidemic trend generally agrees with the actual situation; the model is biologically and logically reasonable; and among the resistant components, the infection probability, the amount of sporulation and the spreading speed of the lesion are in the slow-rust epidemic Plays a major role in the role of latent period Second, the role of infection during the smallest. By changing the initial amount of bacteria and meteorological conditions, it is helpful to analyze the resistance potential of slow rust varieties and estimate their application value.
