本試驗系本研究工作的第五部分,由于此种气体与其他四种較空气为重的常用薰蒸剂不同,其比重较空气力輕,所以进行薰蒸試驗时仍使用同一薰蒸箱,但将其气体发生的位置放置在被薰蒸种籽的下方,并以与气体发生位置相近的(最下层)为第一层,最远者(最上层)为第四层,每层的距离仍为半米。本試驗发生氰酸气所使用的药剂为氰化鈉,其剂量力每立方米30克,加硫酸45毫升及清水90毫升,薰蒸时間为72小时。本試驗所薰蒸的种籽仍与其他
This experiment is the fifth part of this research work. Since this kind of gas is different from other four commonly used fumigants that are heavier than air, its specific gravity is lighter than that of air, so the same fumigation box is still used for the fumigation test. However, the place where the gas is generated is placed below the fumigated seeds and the first layer (the lowest layer) and the farthest layer (the uppermost layer) are the fourth layer in a position close to the gas generation, and the distance Still half a meter. Cyanide gas used in this test reagent is sodium cyanide, the dose of 30 grams per cubic meter, add 45 ml of sulfuric acid and 90 ml of water, fumigation time was 72 hours. The fumigated seeds in this experiment are still different from others
