利用糖厂酒精废液配制的液体肥在甘蔗上的肥效研究

Study on Effect of Liquid Fertilizer Made from Alcohol Waste from Sugarcane Mill on Sugarcane Production

利用糖厂酒精废液配制成液体肥能减少废液的排放污染 ,同时使废液资源化 ,变成肥料得以充分利用 ,其在甘蔗上的施用效果表明 ,7.5 t/ hm2、15 t/ hm2和 2 2 .5 t/ hm2的肥料施用量下 ,蔗茎较习惯施肥分别增产 2 .4 t/ hm2 ,5 .915 t/ hm2和 7.5 4 3t/ hm2 ,增产率达 3.2 9%～ 10 .34% ;分别增糖 0 .99t/ hm2 ,1.16 5 t/ hm2 ,1.36 8t/ hm2 ,增糖率为10 .18%～ 14 .0 7% ,经济效益十分明显。

The alcohol waste liquid from sugarcane mill was used to mix with other fertilizers to form liquid fertilizer,which was applied to sugarcane.The rates of the liquid fertilizer were7.5 t/ hm2 ,15 t/ hm2 and2 2 .5 t/ hm2 ,which increased the yield of the sugarcane by 2 .4 t/ hm2 ,5 .915 t/ hm2 and 7.5 4 3t/ hm2 ,respectively with rate of growth of 3.2 9%～ 10 .34% ,and increased the yield of sugar by 0 .99t/ hm2 ,1.16 5 t/ hm2 and 1.36 8t/ hm2 , respectively with rate of growth of 10 .18%～ 14 .0 7% .The economic benefit from applying the liquid fertilizer to sugarcane was very significant.
