Abstract
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 pekinensis Rupr..The fertilizer was supplemented with manganese sulfate(MnSO4),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.
