在仓房条件、储粮状况基本相同的情况下,进行PH_3和CO_2混合环流熏蒸与粮面布点、风机环流熏蒸的对照试验。研究PH_3和CO_2混合熏蒸时CO_2的增效作用。结果表明:按照每千克AlP(AlP按2.18/m~3计算总用量)配1瓶CO_2钢瓶气(25kg/瓶)进行环流熏蒸时,CO_2浓度在粮堆内过低,达不到专家推荐的4％～8％的增效范围,此时CO_2的增效作用值得商榷。
Under the condition of barn storage and grain storage, the PH_3 and CO_2 mixed circulation fumigation and grain surface distribution, fan circulation fumigation control experiments were carried out. The synergistic effects of CO2 on the fumigation of PH3 and CO2 were studied. The results showed that when circulating 1 fumigated CO2 gas cylinder (25 kg / vial) for every kilogram of AlP (AlP calculated at 2.18 / m ~ 3), the CO 2 concentration was too low in the grain pallets and could not reach the recommended level 4% ~ 8% of the synergistic range, when CO_2 synergistic effect is questionable.
