The invention relates to nitrogen, phosphorus and potassium fertilizer applicable to the spring fertilizing of alfalfa in northern Henan. The nitrogen, phosphorus and potassium fertilizer is applicable to the spring seedling establishment period of alfalfa under soil and weather conditions in northern Henan represented by Yuanyang. The nitrogen, phosphorus and potassium fertilizer is prepared by,by weight percentage, 25% of urea, 65% of diammonium phosphate and 10% of potassium sulfate according to the proportion of 20:26:5. The nitrogen, phosphorus and potassium fertilizer is suitable for being applied in the spring seedling establishment period of alfalfa, and fertilizing quantity of the fertilizer is 150kg*hm<-2>. The spring seedling establishment period of alfalfa is simple and practicable during use, capable of achieving efficient fertilizer utilization, capable of evidently increasing alfalfa yield and quality, capable of increasing fertilizer efficiency and capable of loweringsoil pollution.
