一九八三年的试验结果表明,在杂交水稻繁殖、制种喷施赤霉素时,添加0.01～0.10％的表面活性剂,能增加植株对赤霉素的吸附吸收量,提高赤霉素的使用药效。为了验证这一结果,一九八四年用30、40、50ppm赤霉素作添加0.03％表面活性剂和不加表面活性剂的对比试验,进行形态测量和生理分析。测定结果表明:施用赤霉素添加表面活性剂的处理,株高、节间总长、叶绿素含量、根系活力、茎鞘总糖调运利用率均比对照增高,谷物产量也相应提高,而表面活性剂对种子发芽率无不良影响,显示出一定的增产效果和较佳的经济效益。
The results of the experiment in 1983 showed that the addition of 0.01-0.10% of surfactant to the hybrid rice during propagation and production of gibberellin could increase the uptake and absorption of gibberellic acid The use of efficacy. In order to verify this result, in 1984, the morphological measurements and physiological analyzes were carried out with 30, 40, 50 ppm gibberellin for comparison experiments with addition of 0.03% surfactant and no surfactant. The results showed that the treatment with gibberellin added surfactant increased plant height, total internode length, chlorophyll content, root activity and total sugar uptake and utilization of stems and sheaths than that of the control, and the grain yield also increased accordingly. However, the surface active agent The seed germination rate without adverse effects, showing a certain increase in yield and better economic efficiency.
