摘要：

为了筛选出适合果园微量元素补充的绿肥种质，使绿肥能够更好的在果园中得到应用，测定18种果园常用豆科绿肥植物体内微量元素铁、锌、锰、铜的含量，并对不同作物进行了比较。结果显示：4种微量元素含量最高的是铁元素，其次是锌和锰，铜含量最低；在供试的18种绿肥作物中，狗爪豆花期植物体内4种元素总含量最高，达到了1082 mg/kg；铁含量最高的是狗爪豆（870 mg/kg）；锌含量最高的是狗爪豆（105 mg/kg）；锰含量最高的是小豆（120 mg/kg）；铜含量最高的是狗爪豆（26 mg/kg）。初步认为，狗爪豆对果园土壤微量元素补充能力最强，扁荚山黧豆对果园土壤微量元素补充能力最弱。

Abstract:

18 kinds common leguminous green manure of were analyzed their trace elements (iron, zinc, manganese, copper) content in order to find which kind of green manure was suit to supply trace elements to orchard. The results suggest that the element iron content was the most, the next were zinc and manganese, the least one was copper. Among the tested 18 kinds green manure, trace elements total contents of Stizolobium cochinchinesis was 1082 mg/kg and was the highest one; the highest content of iron element zinc element and copper element were all Stizolobium cochinchinesis and respective 870 mg/kg, 105 mg/kg and 26 mg/kg; the manganese element content of Vigna angularis was 120 mg/kg and was the highest one. The preliminary view of the study was that the most suitable green manure species that could supply trace elements to orchard was Stizolobium cochinchinesis, and the least one was Cicera L.
