摘    要:以万寿菊为试材,采用盆栽试验的方法,研究了污泥提取液施用对万寿菊的株高、茎粗、花产量和直径、生物量的影响,以期为污泥的资源化利用提供参考依据。结果表明:污泥提取液原液氨基酸含量为3.6%,微量元素总量为66.46 mg·L^-1,全溶,偏碱性,有害元素As、Cd、Pb未超过标准规定的含量。氨基酸和微量元素总量虽低于我国含氨基酸叶面肥的标准,但达到市场叶面肥稀释使用要求,稀释后可作为氨基酸叶面肥使用。污泥提取液对万寿菊的生长具有明显的促进作用,株高、生物量、花产量可达到清水喷施的2倍以上,施用效果接近或优于市场的某些叶面肥产品。浓度过高会抑制万寿菊的生长,最佳的稀释倍数为600倍。将污泥提取液进一步制备成氨基酸叶面肥,具有较好的开发应用前景,可实现污泥的资源化利用。

关 键 词:污泥提取液  肥效  万寿菊  植株生长

Abstract:Taking Tagetes erecta L.as test material,the effects of sludge extract on plant height,stem diameter,flower yield and diameter,biomass of Tagetes erecta L.were studied by pot experiments,in order to provide reference for sludge resource utilization.The results showed that the initial solution content of amino acid in sludge extract was 3.6%,and the total amount of trace elements was 66.46 mg·L-1.It was fully soluble,slightly alkaline,and the harmful elements As,Cd,and Pb did not exceed the content of the standard.Although the total amount of amino acids and trace elements were lower than the standards of amino acid-containing foliar fertilizers in China,it could meet the requirement of foliar fertilizer dilution in the market and could be used as amino acid foliar fertilizer after dilution.The sludge extract had a significant promotion effect on the growth of Tagetes erecta L..The plant height,biomass,and flower yield could reach more than twice that of water spraying.The application effect was close to or better than some foliar fertilizer products in the market.The higher concentration could inhibit the growth of Tagetes erecta L.,so the optimal dilution ratio was 600 times.If the sludge extract was further prepared into amino acid foliar fertilizer,which had better development and application prospects,and which could realize the resource utilization of sludge.
Keywords:sludge extract  fertilizer effect  Tagetes erecta L    plant growth
