该技术通过合理设置膜下通风熏蒸系统,在不揭开粮面密闭薄膜和密闭窗户的情况下,利用轴流风机进行膜下通风、环流风机进行膜下粮堆内环流熏蒸,经过一年多的试验,达到了较好的通风和杀虫效果,降低了通风电耗,减少了药剂用量,大大减轻了保防人员的劳动强度,使通风和熏蒸操作进一步简单化,粮堆能长期保持密闭状态,最大限度降低了外界湿热空气对粮堆的影响,大大减少了虫害感染机会,有效地提高了储粮效果。
The technology through the rational establishment of membrane fumigation system under the aeration, not to open the food-grain sealed film and sealed windows under the circumstances, the use of axial fans for under-ventilation, circulation fans for under-mound circulation fumigation, after more than a year Of the test, to achieve a better ventilation and insecticidal effect, reducing ventilation power consumption, reducing the amount of agents, greatly reducing the labor intensity of the security personnel, ventilation and fumigation operations to further simplify the long-term food can remain airtight State, minimize the impact of hot and humid air outside the grain pile, greatly reducing the chance of pest infection, effectively improve the grain storage effect.
