摘要
主要介绍了浅圆仓环流熏蒸生产性杀虫试验效果 .试验表明 :对不同虫情的粮食 ,其熏蒸浓度应控制在 1 0 0～ 2 0 0mL/m3范围 ,密闭 1 5～ 2 5d ,可取得较好的杀虫效果 .此外 ,在采用环流熏蒸时 ,还要考虑产气方式的简便性。
The effects of phosphine circulating fumigation on insects in shallow silo were introduced.As the concentrations of fumigatant were 100 200 mL/m 3,airtight time was 15d,the results was better.In addition,convenience and thrift also should be considered.
