以药剂浓度和熏蒸时间为处理进行了二因素四水平交叉试验。结果表明：以０．３３ｍｌ／ｋｇ／３ｈ处理小薯发芽率最高，且发芽势最强。由于不同品种对药剂作用反应程度不同，研究提出不同品种气体催芽可在０．１３～０．３３ｍｌ／ｋｇ／３～９ｈ的处理范围内选择使用。同时，为了明确药剂使用浓度超过０．５ｍｌ／ｋｇ时是否会造成小薯丧失发芽力，将熏蒸后未能发芽的小薯用３０ｐｐｍ的赤霉素浸泡２５ｍｉｎ处理，３品种均有９０％以上小薯发芽。表明在一定范围内（药剂浓度≤０．７３ｍｌ／ｋｇ，熏蒸时间≤１２ｈ），气体催芽可能抑制小薯发芽，但不会造成其发芽力丧失。
A two-factor, four-level crossover test was conducted with the drug concentration and fumigation time. The results showed that: 0.33ml / kg / 3h treatment of potato yield the highest, and the strongest germination potential. Due to the different degrees of reaction of different species to the agents, it was suggested that the germination of different varieties of gas could be selected within the range of 0.13 ~ 0.33ml / kg / 3 ~ 9h. At the same time, in order to clarify whether the concentration of drug used exceeds 0.5ml / kg, it will cause the loss of germination of small potatoes. The small potatoes which failed to germinate after soaking were soaked with 30ppm gibberellin for 25min, and over 90% Potato germination. Show that within a certain range (drug concentration ≤ 0.73ml / kg, fumigation time ≤ 12h), gas sprouting may inhibit the emergence of small potato, but will not cause the loss of its germination.
