前言近年我省正在逐步开展地下储粮、密闭储粮、磷化氢熏蒸储粮、磷化氢熏蒸降温等保粮方式和方法,当前也正在开展充氮保管和对粮堆循环脱氧等方面的应用技术。概括起来,都是与改变粮堆内或仓房内大气成份和浓度有直接或间接关系的措施。其中有的是以降低粮堆内气体中氧的含量为目的而进行的;有的则在一定条件下,也会形成粮堆或仓房内大气中氧的含量的降低,而且有时是大幅度的降低。从储粮条件来看,氧含量的降低,一般是保持粮质的有利环境条件;但也给我们提出了如何解决工作人员对缺氧的安全防护问题。由于大气缺氧本身没有象常用熏蒸剂的显著的警戒性,掌握不好或麻痹大意,更易造成人身事故。今后应当在保粮实践中,积极地积累经验,以利于储粮技术更加广泛深入地开展。现将搜集到的有关资料,摘其要点加以综合整理,供在探讨中参考。错误的地方,请批评指正。 Preface In recent years, our province is gradually carrying out underground grain storage, closed grain storage, phosphine fumigation storage grain, phosphine fumigation and other food security methods and methods, is also being carried out nitrogen storage and deoxidation of the grain heap and so on Application Technology. In summary, they are measures that have a direct or indirect relationship with changing the composition and concentration of the atmosphere in and around grain storage. Some of which are aimed at reducing the oxygen content of the gas in the grain piles; while others under certain conditions also result in a reduction in the oxygen content of the atmosphere in the grain piles or barns, and in some cases, drastically. From the perspective of grain storage, the reduction of oxygen content is generally an advantageous environmental condition for maintaining food quality; however, it also raises the issue of how to solve the staff’s safety protection against anoxia. As the lack of atmospheric oxygen itself does not like the obvious alertness of commonly used fumigants, poorly controlled or paralyzed, more likely to cause personal accidents. In the future, we should accumulate experience actively in the practice of grain preservation in order to facilitate more extensive and in-depth grain storage technologies. Now collected the relevant information, pick the main points to be consolidated, for discussion in the reference. Wrong place, please comment on criticism.
