平房仓充氮储藏晚籼稻谷,先用复合膜对粮堆“五面”密闭,并有效处理工艺孔洞、工作间等漏气部位,利用移动式制氮机组通过四个进气口结合上充下排、下充上排和仓内环流或环流风机强排等工艺向粮堆充氮。近三个月氮气储藏过程中,氮气浓度维持在95%范围,杀虫率达到100%,并能有效防止害虫发生,次年害虫发生时间推迟近一个月;存粮脂肪酸值年变化量低于1.5(KOH)mg/100g,2009年充氮储藏期内脂肪酸值仅增加0.7(KOH)mg/100g;粮温变化趋势与常规储藏基本一致,但试验仓平均粮温偏高1℃~1.5℃,局部最高粮温变化提前近15d。
平房倉充氮儲藏晚秈稻穀,先用複閤膜對糧堆“五麵”密閉,併有效處理工藝孔洞、工作間等漏氣部位,利用移動式製氮機組通過四箇進氣口結閤上充下排、下充上排和倉內環流或環流風機彊排等工藝嚮糧堆充氮。近三箇月氮氣儲藏過程中,氮氣濃度維持在95%範圍,殺蟲率達到100%,併能有效防止害蟲髮生,次年害蟲髮生時間推遲近一箇月;存糧脂肪痠值年變化量低于1.5(KOH)mg/100g,2009年充氮儲藏期內脂肪痠值僅增加0.7(KOH)mg/100g;糧溫變化趨勢與常規儲藏基本一緻,但試驗倉平均糧溫偏高1℃~1.5℃,跼部最高糧溫變化提前近15d。

Nitrogen filling storage experiment on ate long-grain nonglutinous paddy, first used complex fihn to seal grain stack in five-sides, dealed with the position that leave out air such as abandoned hole and workshop, then used mobile nitrogen generator through four entrance filling nitrogen into grain stack. There are four methods to filling and releasing nitrogen, which were filling up releasing down, filling down releasing up, recirculation under plastic sheet and filling or releasing forced by recirculation blower. Three months experiment showed that while the nitrogen concentration was kept 95%, the mortality rate of the warehouse pest reached to 100%, and the concentration of the nitrogen can also effectively prevent pest occur, the result show that pest occurred suspend almost one month in the next year. The experiment can also stay fatty acid value of the storage grain, the fatty acid value varied under 1.5 (KOH) mg/100 g , the fatty acid value only increased 0.7 (KOH) mg/100 g in the period of nitrogen filling storage course in 2009. The changed law of grain temperature in experiment warehouse was the same as general storage. While compare to general storage, the average of grain temperature in experiment warehouse was more than 1℃- 1.5℃, the highest temperature reached move up 15 days.
