| 摘 要： | 以糖厂酒精废液为追肥(淋施)在甘蔗上进行了施用试验。结果表明,酒精废液在甘蔗生产上作早期追肥对甘蔗的分蘖、生长和提高甘蔗产量有明显的效果。以每667 m2施酒精废液4 t加尿素20 kg和施酒精废液3 t加尿素20 kg效果较好,理论产量分别达6 279.4 kg/667m2和6 065.3 kg/667m2,从节约生产成本和劳动力的角度出发,推荐施酒精废液3 t加尿素20 kg作追肥。

| Abstract: | The alcohol waste liquid was applied in sugarcane as a top dressing to study the effects on growth and yield.The results showed that applying alcohol waste liquid at early growth stage could improve tiller,growth and yield of sugarcane obviously and the theoretical yield of applying 4t/667m2of alcohol waste liquid 20kg/667m2 of urea and 3t/667m2 of alcohol waste liquid 20kg/667m2 of urea was 6 279.4kg/667m2and 6065.3kg/667m2 respectively.The top dressing with 3t/667m2of alcohol waste liquid 20 kg/667m2 of urea should be recommended in sugarcane production. |
