基于臭氧技术的林业病虫害防治效果研究

Research on the Control Effect of Forest Diseases and Insect Pests Based on Ozone Technology

为减少林业病虫害造成的经济损失,确保林业病虫害防治效果,提出基于臭氧技术的林业病虫害防治效果研究。利用制氧机、气液混合泵、灌溉装置和自动控制装置共同组成实验系统。将病虫害防治效果研究分为四个过程,设置每个过程的具体任务。利用光化学法制取臭氧气体,通过改变电源频率调节臭氧水浓度,采用PID控制技术自适应控制灌溉流量大小。研究结果可知,在浓度为6~10 mg/L的臭氧水灌溉下,树木生长速度较快,病株率始终保持较低水平,证明臭氧技术对病虫害防治具有突出效果。

In order to reduce the economic losses caused by forestry diseases and insect pests,ensure the effect of forestry disease and insect pest control,a research on forestry disease and insect pest control effect based on ozone technology is proposed.The experimental system is composed of an oxygen generator,a gas-liquid mixing pump,an irrigation device and an automatic control device.The research on pest control effect is divided into four processes,and the specific tasks of each process are set.Ozone gas is produced by photochemical method,the concentration of ozone water is adjusted by changing the frequency of the power supply,and PID control technology is used to adaptively control the size of the irrigation flow.The results showed that under the ozone water irrigation with a concentration of 6-10 mg/L,the trees grew faster,The diseased plant rate has always remained at a low level,which proves that ozone technology has outstanding effects on pest control.
