在棕壤中对大豆施用过磷酸钙与硝基腐殖酸铵混合物能够取得明显的增产效果。过磷酸钙与低量或高量腐铵混施比两种肥料单独施用更为增产。磷肥利用率可提高6.1％。试验表明,在磷肥与腐肥混施的处理中,土壤有效磷含量比单施过磷酸钙高出6.9ppm。同时,还看到,泥炭腐铵、褐煤腐铵对抑制磷肥的固定作用优于风化煤腐铵。 Soybean in the brown soil application of superphosphate and ammonium nitrate mixture can achieve a significant yield-increase effect. The combination of superphosphate and low or high levels of ammonium fertilizer than the two kinds of fertilizer alone was more yield increase. Phosphate fertilizer utilization rate can be increased by 6.1%. Tests showed that in the treatment of Phosphorus fertilizer and rotting fertilizer, soil available phosphorus content was 6.9ppm higher than that of single superphosphate. At the same time, we can also see that peat, ammonium and brown coal are superior to weathered coal and ammonium for inhibiting the fixation of phosphate fertilizer.
