摘要
以北京市大兴区林业有害生物防控工作为背景,对大兴区林业有害生物的绿色防控方法展开试验和应用研究,对防治结果采用持续跟踪并调查统计分析,取得了具有重要应用意义的成果。试验结果表明:在正确释放花绒寄甲后,花绒寄甲防治光肩星天牛的平均防治率可达55.94%,试验的3块地增加无受害虫树木分别为12、11、16株,能够显著降低园林树木的受害程度;采用释放周氏啮小蜂防治美国白蛾,经正确释放后,调查显示周氏啮小蜂总寄生率达到83.2%,平均寄生率达到62.7%,达到预期效果同时保护了大兴区生态环境;在采用阻隔法防治春尺蠖时,胶带宽度推荐在15~20cm范围,能够取得很好的阻隔效果;色诱法防治柳蜷叶蜂时,黄绿色色卡诱杀柳蜷叶蜂成虫效果最好,黄色次之;经过多年的绿色防控技术的推广,2019年至2021年大兴区减少使用农药近6.47 t,推广生物防治4.762万亩次,物理防治2.1816万亩次。
Taking the prevention and control of forestry pests in Daxing District as the background,the experiment and application research on green prevention and control methods of forestry pests in Daxing District were carried out,and the control results were continuously tracked,investigated and statistically analyzed.The results with important application significance were obtained.After many years of exploration and experiments,the results showed that the average control rate of Dastarcus helophoroides against A.glabrpennis could reach 55.94%after the correct release of Dastarcus helophoroides,and 12,11 and 16 trees without pests were added in the three plots,which could significantly reduce the damage degree of garden trees;the results showed that the total parasitism rate of Chouioia cunea Yang wasp reached 83.2%and the average parasitism rate reached 62.7%,which achieved the expected effect and protected the ecological environment of Daxing District;When using the blocking method to control spring geometrid,the width of the tape is recommended to be 15~20cm,which can achieve good blocking effect;The yellow green color card had the best effect in trapping and killing the adults of P;After years of promotion of green prevention and control technology,Daxing District reduced the use of pesticides by nearly 6.47 tons from 2019 to 2021,promoted 476,200 mu of biological prevention and control as well as 218160 mu of physical prevention and control.
