| 摘 要： | 本试验对充氮气调储粮3种充气工艺在对粮堆充入同量的氮气条件下使用何种工艺可以取得最低氧浓度(最高含氮量),取得最理想的杀虫效果即最佳经济效益进行了探索。试验证明,密闭条件下从粮面向粮堆充气,当气囊鼓起使粮膜离开粮面时,在向粮堆继续充气的条件下打开地槽口排气阀排气,当打开地槽口排气阀后继续充入的气量相当于粮堆内空气量时停止充气,停止排气,将仓房密封好,环流均匀后氧浓度最低(氮浓度最高),吨粮成本最低。

| Abstract: | The experiment is attempted to explore how the three kinds of grain storage nitrogen charging process,when inflated with the same amount of nitrogen,can achieve the minimum oxygen concentration or the highest nitrogen content,get the highest insecticidal effect that gain the best economic benefit.The experiment proves that inflae the heap of grain when the airbag summon up to make the grain membrane away form its surface,open the discharge valve exhaust slot without stopping the inflation;stop inflating and exhausting and seal the barn when the nitrogen filled after opening the valve exhaust slot equals that of the inside of the grain.Then it can achieve the minimum oxygen concentration and the lowest cost of tons of grain. |
