摘要
与ＧＡ３单独处理相比，ＧＡ３与表面活性剂粤辅３号（ＹＦ３）混合使用，可降低ＧＡ３的表面张力及其受雨水冲刷程度，部分地溶解叶表面的硅质、蜡质和角质，使秧苗对ＧＡ３的吸附量增加３～５倍，吸收量加１～３倍；增加水稻幼苗的株高６７％。
Comparing with GA 3 treatment alone,the spraying of GA 3 combined with surfactant YF 3 upon rice seedlings could increase the seedlings height by 67%,enhance the adhesion and uptake of GA 3 in rice seedlings by 3-5 times and 1 to 3 times,respectively.The silicon,wax and cuticle in surface of leaves wrer partly dissolved by YF 3.Moreover,YF 3 had a function of rainfastness,which reduced the percentage of GA 3 to be washed away.
