摘要
应用相关回归方法 ,分析了黑松接种松材线虫后 ,病害的潜育期与环境中的日平均温度、日平均日照时数的关系。结果显示 ,病害潜育期与日平均温度呈极显著负相关 ,与日平均日照时数呈显著负相关。
By means of the related regression,the relationships between the latent period of the wilt disease of Pinus thunbergii,caused by Bursaphelenchus xylophilus,and the mean daily temperature(MDT)and mean daily sunshine time(MDST),were analysed.Results showed that the latent period was negatively correlated with MDT in 1%,and with MDST in 5% significance level.
