摘要
对白龙江林区云杉人工示范林进行病虫害监测调查,结果表明:每hm2云杉人工示范林样地内有3种常见的有害生物危害,即云杉落针病、云杉叶锈病和杉针黄叶甲,感病指数分布为3级、1级和3级。通过化学和烟剂防治手段,病虫害蔓延得到有效控制,为白龙江林区森林提供相关技术参考。
The pest of Picea asperata artificial demonstration forests was monitored and surveyed in Bailongjiang forest area,the results showed that： There are three kinds of common pest in artificial demonstration forest plots of P. asperata per hm2,that is Lophodermium piceae, Chrysomyxa qilanensis and Xanthonia collaris.
