摘　　要：目的:以四川道地药材泽泻为材料,研究不同生育时期喷施不同浓度的烯效唑对其产量、主要药用成分的影响。方法:采用HPLC技术检测块茎中主要药用成分泽泻醇A-24-醋酸酯和泽泻醇B-23-醋酸酯的含量。结果:移栽后36 d(A1),56 d(A2)期施药各处理主要药用成分的含量均出现B1>B2>B3>B4>B0的规律,各浓度施药处理生产量均极显著高于对照组,A1期的要极显著高于A2期,A1期又以80 mg.kg-1处理效果最佳,且在采用高效液相色谱法,检出限为0.316 8 mg.kg-1的条件下,各浓度处理均未测出残留污染。结论:在移栽后36 d叶面喷施80 mg.kg-1烯效唑最佳。To study the effect of S-3307 on the yield and main ingredients of Alisma plantago-aquatica. Method： The contents of 24-aeetyl alisol A and the 23-acetyl alisol B in tuber were determined by HPLC. Results ： The contents of 24-aeetyl alisol A and the 23-acetyl alisol B as well as yield were significantly increased in all groups applied with different concentrations of S-3307 comparing with control group. The optimal concentration of S-3307 was 80 mg· kg^-1. The residues of S-3307 was detected under 0.316 8 mg· kg^-1 （detecting limit）. Conclusion： The optimal concentration of S-3307 is 80 mg· kg^-1, it reached the best result when applied 36 d after seedling.
