【摘要】 为促进甘蔗酒精生产废液的资源化利用,为农作物提供有效的肥料资源及相关水肥管理模式,对比研究了甘蔗地上施用甘蔗酒精生产废液、化肥及不施肥等处理对水分、铜和氯养分吸收及流失的影响,并对施用甘蔗酒精生产废液的食品安全性和对地表水环境污染的影响进行了评价。结果表明,与化肥处理CK2相比,甘蔗酒精生产废液的施用提高了土壤的水分利用率,降低了甘蔗中铜的含量及铜的径流流失,提高了甘蔗中氯的含量,但各处理蔗汁或径流水中的铜、氯含量或浓度远低于国家标准值。认为在该试验条件下富含有机质的甘蔗酒精生产废液在蔗地上施用,对蔗糖及地表水环境质量没有不良影响,值得推广应用。更多还原

【Abstract】 This study was conducted in a sugarcane field in order to promote vinasse application as an effective fertilizer resource and develop a mode of water and nutrient management in sugarcane fields.Three treatments were designed as follows:CK1(no fertilizer treatment),CK2(chemical fertilization treatment),vinasse(75 t/hm2 vinasse treatment).The effects of three treatments on soil moisture,Cu,and Cl uptakes by sugarcane and runoff losses were investigated and food safety or environmental contamination in surface runoff water was assessed.Results showed that the application of vinasse increased soil moisture utilization rate and decreased Cu content in sugarcane and surface runoff,as compared with treatment CK2.However,the application of vinasse increased Cl content in sugarcane and Cl contents or concentrations in sugarcane juice or runoff for all treatments were far less than GB value.It is concluded that in this experimental condition vinasse(containing much orgnic matter)application to sugarcane field decreases water and copper loss,but no serious consequence is found on quality of sucrose and surface water environment.Vinasse is suitable for sugarcane field application.更多还原
