摘要
针对草地主要危害种群的三龄蝗虫,在测量分析其跳跃特性的基础上,以吸捕率为目标,以机器前进速度、吹吸口气流速度、吸头距地高度等3个可控参数及一个交互作用为试验因素,用正交试验设计安排了草地蝗虫吸捕机的实地试验。试验结果表明,对吸捕率的影响次序依次为:吸头距地高度、机器前进速度、交互作用、吹吸口气流速度;当吸头距地高度为18cm、吹吸口气流速度为23/21(m/s)、机器前进速度为2.4m/s时,吸捕率可以达87.5%。试验数据为草地蝗虫吸捕机吸捕作业及调整提供了有价值的参考。
The article concerns with analyzing the skipping characteristics of the third-instars grasshopper. Then Aiming to improving the trapping rate, we adopted the orthogonal experimental design for the field experiment of the grasshopper pneumatic trapper with three controllable factors including the height of the suction mouth above ground surface, the trapper＇s advance speed, the interaction and the airflow speed at the exhausting and intake speed, and an interaction. The results show that the order of the influence on the trapping rate is the height of the suction mouth above ground surface, the trapper＇s advance speed, the interaction, the airflow speed at the exhausting and intake speed. When the height of the suction mouth above ground surface is 18cm, the trapper＇s advance speed 2.4m/s, the airflow speed at the exhausting and intake speed 23/21m/s, the best trapping rate is above 87.5%. The results and analysis provide valuable information for grasshopper pneumatic trapper＇s working and adjusting effectively.
