一种实验生产改良气体的装置被设计和安装。使用CO_2、N_2和O_2(气体范围0～100％)产生混合气体。这种装置可用来测定气体成分、暴露时间、温度和相对湿度对锈赤扁谷盗成虫和卵死亡率的影响。CO_2浓度为70％、80％和90％,O_2浓度为0,4％和8％(用N_2平衡),相对湿度65％、75％和85％;气流速度为55±2毫升/分;暴露时间24、48、60、72、84和96小时;温度10、15、20℃时可引起锈赤扁谷盗成虫死亡。在两种氧浓度(0和4％),两种温度(10和20℃),相同的CO_2浓
An experiment to produce a modified gas device was designed and installed. The use of CO_2, N_2 and O_2 (gas range 0 ~ 100%) to produce a mixed gas. This device can be used to determine the effect of gas composition, exposure time, temperature and relative humidity on adult and egg-mortality rates of Picea obliquus. CO 2 concentrations of 70%, 80% and 90%, O 2 concentrations of 0, 4% and 8% (balanced with N 2), relative humidity of 65%, 75% and 85%; air velocity of 55 ± 2 ml / min; Time 24,48,60,72,84 and 96 hours; temperature 10,15,20 ℃ can cause adult death of Corallon rust. At both oxygen concentrations (0 and 4%), both temperatures (10 and 20 ° C), the same CO2 concentration
