本试验用仓外混合熏蒸机以磷化氢和二氧化碳混合熏蒸方式处理有虫小麦.结果表明,用这种新方法能够大大提高磷化氢的渗透速度以及C·T积值,磷化氢最高浓度维持时间较之单一熏蒸方式延长了一倍.
In this experiment, mixed wheat fumigation with a mixture of phosphine and carbon dioxide fumigation treatment of insect pests.The results show that the use of this new method can greatly improve the penetration rate of phosphine and C · T plot value, the highest phosphine Concentration maintenance time than a single fumigation doubled.
