| 摘 要： | 在云南省曲靖市开展2组旱地玉米田间小区试验，研究不同磷钾施肥量对玉米生物量和养分的积累、养分利用和产量的影响。结果表明，玉米氮磷钾养分吸收积累高峰期在抽雄期；磷素和钾素的供应对玉米产量有显著影响，钾素的影响大于磷素。P 120 kg/hm2、K 75 kg/hm2(P2K2)处理搭配合理，地上部分的生物量积累和子粒产量在所有处理中最高，产量比其他处理高3.90%～24.74%。P 60 kg/hm2、K 75 kg/hm2(P1K2)处理的磷肥利用率和磷素农学效率较高。P2K2处理的钾肥利用率和钾素农学效率较高。

| Abstract: | The field experiments were conducted to investigate the effects of phosphorus, potassium levels on NPK accumulation amounts, yield and fertilizer utilization rate of maize on upland in Qujing city of Yunnan province. The results indicated that the high rate of NPK accumulation of maize appeared near heading stage. Different P and K levels had significant effects on yield of maize. K effect on maize was larger than that of P. Biological yield and maize yield with P2K2 were the highest in all treatments. Yield with P2K2 was higher than that with other treatments by 3.90%-24.74%. P utilization rate and agronomic P efficiency of maize with P1K2 were higher than those with other treatment. K utilization rate and agronomic K efficiency of maize with P2K2 were higher than those with other treatments. |
