研究结果表明:云杉幼树主干新梢生长量损失率与大栗鳃金龟幼虫虫口密度之间呈极显著的正相关线性关系,虫口密度越大,云杉主干新梢生长量损失率越高;临夏州大栗鳃金龟幼虫田间治指标确定为3头/m2。
The results showed that there was a significant positive linear correlation between the loss rate of growth of spruce young shoots and the population density of Larvae Galliana larvae. The higher the population density of spruce, the higher the loss rate of sprout growth was. Linxia red chestnut beetle larvae field governance indicators identified as 3 head / m2.
