| 摘 要： | 2006年,对广西扶绥县原施常规化肥10年(1996～2005年)的甘蔗地施用酒精发酵液75t/ha+钙镁磷肥0.75t/ha,研究其对土壤、甘蔗及地表水域养分含量的影响.结果表明,与原始土壤相比较,两种施肥方式都能显著提高甘蔗地土壤氮、磷、钾养分和pH,而显著降低有机质含量.与施用常规化肥相比,混施酒精发酵液与钙镁磷肥可显著提高土壤总N、总K、有效N和有效K含量以及蔗渣和蔗汁K含量,有利于提高土壤总晗量和pH、甘蔗产量和产糖量,塘水N、P养分远低于国家标准限定值.因此,蔗地施用酒精发酵液可以提高土壤肥力、增加甘蔗产量和产糖量,且未对蔗地地表水域造成不良影响.

| Abstract: | In 2006,in order to study the effects of vinasse from sugar mill on nutrient contents in soil,sugarcane,and surface water of sugarcane field,75t /ha vinasse + 0.75t /ha calcium magnesium phosphate and common chemical fertilizer were applied to sugarcane field in Fusui County,Guangxi,which had applied common chemical fertilizer for 10 years(1996-2005) . The results showed that,compared with the origin soil,two fertilizing treatments could increase the contents of nutrients N,P,K and pH of soil significantly,... |
