| 摘 要： | 本文研究了大豆连作下,土壤与植株体内锰营养的变化情况。结果表明,不同生长期各施肥处理大豆连作土壤中有效锰都高于轮作土壤,但连作大豆植株体内锰累积吸收量却低于轮作。不同施肥处理轮作和连作土壤中有效锰含量、植株体内锰累积吸收量的大小排列顺序为。施有机肥:秸秆还田>施用化肥>对照。

| Abstract: | The Mn nutrition in soil and soybean plant under long-term successive planting were studied in the paper. The results showed that the content of available Mn in sowing soil of continuous cropping of different growth stages in different fertilization were higher than that of rotation. But the content of the uptake and accumulation Mn were lower than that of rotation. The contents of uptake and accumulation Mn in plant were OM>TS>NP>CK. |
