摘　　要：介绍富氮低氧气囊微正压保持技术杀虫原理和操作要点:氮气气调快速降氧后,通过多次补气,保持粮面富氮低氧的气囊充分鼓起并维持气囊微正压状态,控制氧气浓度在3%以下3~6个月,达到彻底杀灭储粮害虫的目的。此项技术是目前我国桂东南实现高标准"无虫"状态的主要手段。The paper introduce the insecticidal principle and operation points of micro-positive pressure holding technology with nitrogen-rich hypoxic film-bag. After rapid oxygen reduction by nitrogen-controlled atmosphere, the nitrogen-rich hypoxic film-bag on grain surface are fully bulged up and maintained under micro-positive pressure, and the concentration of oxygen is controlled below 3% for 3-6 months, so as to completely kill stored grain insects. It is the main technical means to realize the high standard "insect-free" state in the grain storage ecological region of south eastern Guangxi.
