The invention discloses a PASP nitrogen fertilizer mixed application method for hybrid rice.When PASP urea partially replaces common urea to be used as base fertilizer, PASP urea accounts for 60%, and common urea accounts for 40%; when PASP urea partially replaces common urea to be used as panicle fertilizer, PASP urea accounts for 50%, and common urea accounts for 50%.The PASP nitrogen fertilizer mixed application method for hybrid rice includes the steps that firstly, 50-60% of nitrogen fertilizer needed in the whole-growth period is evenly scattered in field according to mixed fertilizer of PASP urea and common urea in the PASP nitrogen fertilizer mixed application method for hybrid rice after the field is subjected to rotary tillage for the first time, then the field is subjected to rotary tillage again, and fertilizer and soil are fused; secondly, remaining nitrogen fertilizer serves as top dressing, and mixed fertilizer of PASP urea and common urea is applied in the early stage of first bud primordium differentiation of stem young ears, a simplified and efficient rice fertilization mode through special nitrogen fertilizer of PASR urea is put forwards, a balance point is found between labor saving and high efficiency, and efficient utilization of fertilizer is taken into consideration while labor is saved.
