本試驗系本研究工作的第三部分,试验方法及种籽种类与第二部分的二氯乙烯对十种农作物种子的薰蒸及发芽試驗完全相同。本試驗所使用溴甲烷的品質含系有效成分98％的标准品,使用剂量及薰蒸时間也以上海市粮食油脂公司所常用能达杀虫率100％的剂量与时間为标准,即每立方米为35克,时間为48小时。关于溴甲烷薰蒸农作物种籽后对发芽力的影响,有若干試驗报告,但是有很多是非常矛盾的,例如S. S. Easter、F. W. Fisk及R. Latta等均認为,用溴甲烷薰蒸,对豆类及谷物种籽的发芽一般无害,或为害极少。但据R. T. Cotton报告,则
This experiment is the third part of the research work, test methods and seed types and the second part of the dichloroethylene fumigation and germination of ten kinds of crop seeds exactly the same experiment. The quality of the methyl bromide used in this experiment includes 98% of the standard active ingredients. The dosage and fumigation time are also based on the dosage and time of 100% insecticidal rate commonly used by Shanghai Grain and Fat Company. 35 cubic meters, the time is 48 hours. There have been a number of reports on the effects of methyl bromide fumigation on the germinating power of seeds. However, there are many contradictions. For example, SS Easter, FW Fisk and R. Latta both believe that fumigation with methyl bromide And the germination of cereal seeds is generally harmless, or extremely harmful. However, according to R. T. Cotton, then
