【摘要】 蚕豆能同等程度地利用EXC—Zn、OM—Zn和R₂O₂—Zn等有效态锌,并能促进土壤中难溶态RES—Zn和CA—Zn向EXC—Zn和R₂O₃—Zn转化。同时,能减少施入土壤的水溶态锌转化成RES—Zn的比例,从而使土壤中的锌保持较高活性。水溶态锌在土壤中的分布为:中性及钙质土CA—Zn>R₂O₃—Zn≥OM—Zu>RES—Zn>EXC—Zn;酸土为:R₂O₃—Zn>OM—Zn≥RES—Zn>EXC—Zn。更多还原

【Abstract】 EXC—Zn, OM—Zn and R₂O₃—Zn in soils can be absorbed by broad bean equally. Broad bean cultivation can promote soil RES—Zn and CA—Zn transforming into EXC—Zn and R₂O₃—Zn, and making the fertilizer—Zn applied to soils maintain high activity. The contribution order is CA—Zn>R₂O₃—Zn>OM—Zn>RES—Zn>EXC—Zn in calicium and neutrial soils, or R₂O₃—Zn>OM—Zn≥RES—Zn>EXC—Zn in acidic soils under the cultivation of broad bean.更多还原
