害虫侵袭作物导致减产,但估计产量损失程度时,有时把害虫的为害率当作产量的损失率计算,未考察受害作物的补偿能力,常使产量结果与为害程度及防治效果不符。为此,两年来我们进行了谷田钻蛀性害虫的不同为害程度与产量损失的补偿效应之模拟 Insect infestation crops lead to reduced production, but when estimating the degree of yield loss, sometimes the damage rate of pests is taken as the loss rate of production, the compensation ability of the damaged crops is not examined, and the output result is often inconsistent with the damage degree and the prevention and control effect. For this reason, in the past two years we have conducted a simulation of the compensation effect of the different damage degree and yield loss of borer pest insects
