摘　　要：通过“Ｓ－０７”对双季晚稻增产效应的研究，结果表明：“Ｓ－０７”对水稻秧苗有明显的矮化、促蘖效应；凡经“Ｓ－０７”处理的产量结果均比清水对照极显著增产；其中“Ｓ－０７”６０ｍｇ／ｋｇ秧苗一叶一心期喷施的处理及“Ｓ－０７”１００ｍｇ／ｋｇ浸种的处理效果最佳。高效唑无论对杂交水稻或常规水稻都同样具有显著的生理效应。The experimental results showed that S-07(Uniconazole)effectively reduced the plantheight and promoted the tillering of rice seedlings.The rice treated with S-07 increased theyield significantly as compared with that of the control spraying 60 mg/kg S-07 solution at thestage of one mature leaf and one new leaf of rice seedlings and soaking seeds with 100 mg/kgS-07 solution had the best effects.The S-07 treatment had similar physiological effects on bothhybrid and coventional rice.
