| 摘 要： | 研究了大豆连作条件下,土壤中有效Zn与植株体内Zn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Zn都高于轮作土壤,但连作大豆植株体内Zn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Zn含量、植株体内Zn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 Zn nutrition in soil and soybean plant under long-term successive planting was studied.The results showed that under different fertilizations,the content of available Zn in continuous cropping soil at different growth stages were higher than that in rotating of crop,while,the uptake and accumulation of Zn in soybean plant were lower than that in rotation.Fertilization also had effects on Zn nutrition,and under continuous cropping of soybean and rotating crop,the content of available Zn and the uptake and accumulation Zn in plant were OM>TS>NP>CK. |
