Analysis on the occurrence species and Control techniques of main pests in Pinus tabulaeformis artificial Pure Forest in Qingyang City

油松是松科针叶常绿乔木,是我国特有的树种,原产地在我国的东北、中原、西北和西南等省区。近年来,随着国家大力推进生态文明建设,贯彻绿色发展理念,甘肃省庆阳市油松人工纯林的覆盖率越来越高。但因林种单一,导致生态环境比较脆弱,有害生物发生率较为频繁。基于此,分析甘肃省庆阳市油松人工纯林主要有害生物发生物种,并提出有效的防治技术,以供营林生产中参考。

Pinus tabulaeformis is an evergreen tree of Pinus tabulaeformis,which is a unique tree species in China,which originated in Northeast,Central Plains,Northwest and Southwest provinces of China.In recent years,with the national promotion of ecological civilization and the implementation of the concept of green development,the coverage rate of Pinus tabulaeformis artificial pure forest in Qingyang City,Gansu Province is getting higher and higher.However,because of the single forest species,the ecological environment is fragile and the incidence of pests is more frequent.Based on this,the main pest species of Pinus tabulaeformis artificial pure forest in Qingyang City,Gansu Province were analyzed,and the effective control techniques were put forward for reference in forest production.
