摘要
采用室内培养方法,研究了施用糖蜜酒精废液对土壤理化性质的影响。结果表明,土壤施用糖蜜酒精废液后,土壤的pH和土壤容重都有所下降,土壤有机质、有效氮、速效钾、有效镁的含量随糖蜜酒精废液施用量的增加而明显提高,显示糖蜜酒精废液可以作为液体肥料施用。蔗地施用酒精废液,可以减少酒精废液对环境的污染,从而变废为宝。
Effects of vinasse on the soil properties was studied with indoor culture methods. Results showed that pH value and bulk density of the test soil decreased with the application of vinasse. And the available N,K,Mg and organic matter content of the soil significantly increased. Thus vinasse can be used as a kind of liquid fertilizer. Application of the the venasse to soil can reduce the enviromental pollution and change it from waste to treasure.
