摘要/Abstract

摘要： 针对设施农业中连作引起的土壤污染、线虫增加等问题，设计一款基于臭氧杀菌技术的旋耕式土壤消毒机。介绍旋耕式土壤消毒机整体结构，对臭氧充气铲进行受力分析，获得臭氧注入土壤的运动学条件，确定充气铲结构参数；以XC224RC控制器为电路控制模块核心元件，采用高压放电法制取臭氧，实现臭氧发生器正常运行；利用SolidWorks软件构建整机结构模型，进行样机研制与试验。以根结线虫为试验对象，相同的试验条件下，常规耕整1次的线虫消退率为2.96%，臭氧消毒处理后根结线虫消退率和防治效率最高可达84.93%和84.47%，较常规耕作线虫消退率提高81.97%。

Abstract: Aiming at the problems of soil pollution and increase of nematodes caused by continuous cropping in facility agriculture, a rotary tillage soil disinfection machine based on ozone technology was designed. The structural parameters of the rotary tillage soil disinfection machine was designed and calculated, the force of the ozone inflatable shovel structure under the action of motion was analyzed, the kinematic conditions for ozone injection into the soil was obtained and the structural parameters of the inflatable shovel was determined. The XC224RC controller was used as the core component of the circuit control module, and the ozone was extracted by high voltage discharge method to realize the normal operation of the ozone generator. The SolidWorks software was used to build the whole machine structure model, and the prototype was developed and tested. Using the rootknot nematodes as a test, under the same experimental conditions, the nematode regression rate of conventional tillage was 2.96%, and the maximum nematode regression rate and control efficiency of rootknot nematode were 84.93% and 84.47% after ozone disinfection, which was 81.97% higher than that of conventional tillage.

Key words: facility agriculture, soil disinfection machine, ozone disinfection, ozone inflatable shovel, rootknot nematode
