摘　　要：采用盆栽试验,研究复混肥中添加不同形态锰对大白菜Brassica pekinensis Rupr.产量及品质的影响,复混肥中分别添加硫酸锰(MnSO4)、氨基酸螯合锰(Mn-AA)和EDTA螯合锰(Mn-EDTA),施锰量分别为0.2、0.5、1.0、1.5和2.0 mg.kg-1.结果表明,与不施锰对照相比,适量添加锰能提高大白菜的产量,均以施锰1.0 mg.kg-1效果最佳,添加Mn-AA增产幅度最大,可增产15.7%;施锰1.5和2.0 mg.kg-1时,添加MnSO4和Mn-EDTA处理小幅减产,添加Mn-AA处理增产的幅度降低;适量添加3种形态锰均可提高大白菜叶绿素相对含量(SPAD值);添加Mn-AA组对提高大白菜的品质最佳,可有效提高可溶性蛋白质及维生素C的含量,降低亚硝酸和硝酸盐含量.The pot experiment was carried out to study the effects of different combined manganese ion added to compound fertilizer on yield and quality of Brassica pekirtertsis Rupr.. The fertilizer was supplemented with manganese sulfate （MnSQ）, amino-acid chelated manganese （Mn-AA） or ethylenediamine tetra acetic acid disodium manganese （Mn-EDTA）. There were five levels of Mn concentration, namely Mn 0. 2,0. 5,1.0,1.5 and 2.0 mg·kg^-1 Adding appropriate combined manganese ions might increase the yield of B. pekinensis ; the maximum production with 1.0 mg·kg^-1 Mn-AA application increased by 15.7% ; the application of MnSO4 or Mn-EDTA lead to decrease the yield. The application of 1.5 and 2. 0 mg ·kg^-1 Mn-AA reduced the production. Application of appropriate manganese could increase the SPAD value. The application of appropriate Mn-AA improved the quality, increasing soluble protein and vitamin C, decreasing the contents of nitrite and nitrate.
