摘    要:通过对北镇地区氮磷钾不同配比模式对水稻的影响效果进行试验。结果表明,推荐施肥区、习惯施肥与推荐施肥搭配区的产量高于其他处理的水稻产量,肥料利用率高些,增产效果好,经济效益显著。其中以推荐施肥N-14.2、P-7、K-7的配方最佳,但此施肥配方易受土壤条件和气候制约,需因地制宜,予以应用。在生产实际中,氮磷钾肥施用以1/3氮肥、全部磷肥、2/3钾肥做底肥,后期追施2/3氮肥和1/3钾肥为最佳施肥模式,能够达到高产、稳产、高效的目的。

关 键 词:水稻  施肥配方  施肥模式  应用效果

Abstract:Effects of different NPK application rates on rice were studied in this experiment in Beizhen.The results showed that the recommended fertilizer application treatment,the traditional fertilizer application treatment and recommended fertilization collocation treatment got higher yield and fertilizer efficiency.The recommended fertilizer application modes of N-14.2、P-7、K-7 were best but these modes were easily affected by local soil conditions and climate.So these modes should be used according to local conditions.Aimed at getting high and stable yield and high efficiency,the recommended fertilizer mode was 1/3 nitrogen,all phosphorus and 2/3 potassium as based fertilizer,2/3 nitrogen and 1/3 potassium as top-dressing fertilizer at later stage.
Keywords:Rice  Fertilizer protocol selection  Application mode  Application efficiency
