摘要
综合8个玉米"3414"肥料效应试验和4个玉米氮、磷、钾肥料利用率试验数据,分析并阐述兴仁县玉米氮、磷、钾利用率的现状,得出玉米氮、磷、钾肥的利用率分别为29.5%、24.5%和40.9%,为今后玉米种植中测土配方施肥的配方合理化和寻求提高氮、磷、钾利用率的途径提供了理论依据。
8＂3414＂ feritilizer tests and 4 NPK fertilizer utilization rate tests of maize were summarized,NPK fertilizer utilization rate status in Xingren was analyzed, it＇s obtained that NPK fertilizer utilization rate were 29. 5%, 24. 5%, 40. 9% respectively, it＇s provided the basic materials for soil testing and formula fertilization and improve the utilization rate of NPK of maize in future.
