应用大田抽样调查的方法组建了稻纵卷叶螟幼虫数量和卷叶率的多项式方程,可纳入卷叶螟的系统模型中应用。并初步揭示了穗颈稻瘟对卷叶螟产量损失的交互影响。
A polynomial equation of the number of larvae and leaf rolling rate of C. medinalis was established by field sampling method and could be applied to the systematic model of leafroller. And initially revealed the interaction between panicle blast of rice leaf roller Yield loss.
