摘　　要：研究了烤烟不同播期使用烯效唑化控对产量、产值的影响。结果表明:12月30日播种,浓度为30mg/kg(A3B2)的烤烟生育状况最好,每公顷产量最高(1935.9kg)、产值最佳(12757.58元/hm2)。12月20日播种,浓度20mg/kg(A2B1)的产量和产值次之,每hm2分别为1443.15kg、8864.7元。12月10日播种,浓度为20mg/kg、50mg/kg和12月30日播种,浓度为50mg/kg及CK产量、产值最差。The effect of the chemical of uniconazole use in flue-cured tobacco in different seedtimes on its yield and production value was studied. The results were as follows: The procreative condition of flue-cured tobacco was the best when it was inseminated on December 30 and the concentration of the chemical was 30 mg/kg(A_3B_2). Its yield was 1 935.9 kg/hm^2,and its production value was 12 757.65 yuan/hm^2. The procreative condition came the next when it was inseminated on December 20 and the concentration was 20mg/kg(A_2B_1). Its yield and its production value were1 443.15 kg,8 864.7 yuan/hm^2 respectively. And the procreative condition of flue-cured tobacco was the worst when it was inseminated on December 10 and the concentration of 50 mg/kg. And the yield and production value of the CK were also the worst.
