摘 要 ：浙江省61个具有代表性的复混肥料、有机-无机复混肥料和有机肥料产品的养分含量、物理性状及重金属含量的检测结果表明,浙江省复混肥料、有机-无机复混肥料、有机肥料的养分含量和物理性状总体较好。三类肥料的养分含量合格率分别为:有机肥料95.0%、有机-无机复混肥料72.2%、复混肥料86.3%。从三类肥料的重金属含量的检测情况看,有机肥料中的铜、锌、铅、镉、铬含量均高于有机-无机复混肥料和复混肥料,而且高含量段的分布频率也大。按相应标准判定,有机肥料中35%的样品镉含量超过限量标准,10%的样品铅含量超过限量标准,所有样品的铬含量均在限量标准内;有机-无机复混肥料样品中三种重金属元素均在限量标准内。对有机肥料中的有机肥肥源的重金属含量检测结果表明,有机肥料与其相应的有机肥源中的铜、锌、铅、镉、铬等五种重金属元素的含量均呈显著正相关。

Abstract:An investigation was carried out on the physical and nutritional quality of fertilizers in Zhejiang province.Analysis results of 61 samples collected from domestic compound fertilizers,organic-inorganic compound fertilizers and organic fertilizers showed that majority of the samples met the relevant standards listing criteria.For the criteria for nutrient of these fertilizers was 95.0% for organic fertilizers,72.2% for organic-inorganic compound fertilizers,and 86.3% compound organic fertilizers.Heavy metals were also tested.The results showed that Cu,Zn,Pb,Cr and Cd contents were highest in organic fertilizers followed by organic-inorganic compound fertilizers.Cd and Pb contents of organic fertilizer samples was 35% and 10% higher than the upper limitation of national standard respectively,while Pb,Cd and Cr in all organic-inorganic compound fertilizers samples measured under the national standard.The contents of heavy metals in commercial organic fertilizers were significantly correlated with that in the raw organic materials.
