摘　　要：研究了双玉(春、夏两季玉米,下同)、菜立体种植中双玉米超高产对氮、磷、钾的吸收、运转及利用规律。结果表明,双玉米氮、磷、钾累积吸收量、累积吸收速率和累积利用率的时段变化类同,即随生育期的推进呈递增趋势,前二者与施肥量呈正相关,后者与施肥量呈负相关。春玉米对肥料氮、磷、钾的吸收量和利用率均远高于夏玉米。Studies on change rule of fertilizer absorption, transport and utilization by spring and summer maize for super high-yielding in stereo planting of spring and summer maize and vegetable, study pairs of dish three-dimensional to is it compound colony pairs of maize ultra high yield to indicated the period change of accumulated absorbing amount, absorbing of speed and utilization ratio of three key elements of spring and summer maize is similiar. There was a tendency to increase progressively with growing time. Both two former showed positive correlation and the two latter showed rative correlation with fertilizer amounter. The spring maize is higher than the summer maize on absorpting fertilizer nitrition.
