摘要
为探索玉米氮肥、磷肥和钾肥的利用率,掌握配方施肥减少肥料用量,提高氮肥、磷肥和钾肥利用效果,特进行夏玉米肥料利用率试验研究。结果表明:配方施肥下,施肥量减少75kg/hm2左右,氮磷钾肥利用率平均提高9.13%,增产率超过5%。
The experiment on fertilizer using efficiency of summer maize was conducted to explore the us-ing efficiency of nitrogen,phosphate and potash,master the approach of formula fertilization,reduce the use of fertilization and increase the utilization of fertilization. The results indicated that the fertilizer application amount reduced by 75kg/hm2,while the average utilization efficiency of nitrogen,phosphate and potash in-creased by 9.13% and the yield increase rate of summer maize was over 5%.
