大豆锰磷配合施用的研究

Application of Manganese in Combination with Phosphorus in Soybean Cultivation

盆栽试验表明,锰肥能促进大豆(GLycine max(L.)对磷的吸收和体内DNA、RNA的形成;磷肥同样也能促进大豆对锰的吸收,锰磷配合施用有利于大豆干物质的形成。田间试验表明,锰磷最佳配比为0.34:1。MnSO:P_2O_5)

The pot-culture experiment shows that manganese fertilizer can pro- mote soybeans to absorb phosphorus and to form DNA and RNA in its inner part. At the same time, phosphorus can also promote soybeans to absorb manganese.It's beneficial to use manganese and phosporus fertilizers toge- ther for soybeans to form dry matter. The experiment in fields has shown that the best proportion of phosphorus and manganese is 1:0.34(P_2O_5:Mn- SO_4).
