不同氮磷施肥量对玉米生育期土壤微生物量的影响

Effect of different amounts of nitrogen and phosphorus fertilizers applied on soil microbial biomass during corn growth periods

  • 摘要: 通过田间小区试验研究了不同N、P施肥量对玉米生育期土壤微生物量C、N、P的影响。结果表明,不同N、P施肥量对微生物量C无明显影响;施N肥量高(225kg/hm2)时降低微生物量N;当施P肥达225kg/hm2时则对微生物量P产生明显的抑制作用。

     

    Abstract: The effect of different amounts of nitrogen and phosphorus fertilizers applied on soil microbial biomass carbon, biomass nitrogen and biomass phosphorus was studied during corn growth periods through the field plot experiments. The results showed that different amounts of nitrogen and phosphorus fertilizers applied have no distinct effect on microbial biomass carbon. While the amount of nitrogen fertilizer applied is 225 kg/hm2, microbial biomass nitrogen will be reduced. It also has obviously inhibiting effect on microbial biomass phosphorus when the amount of phosphorus fertilizer applied reaches to 225 kg/hm2.
