The purpose of this study is to investigate the fertilizer and fertilizer use conventional fertilization on wheat production, provide technical basis for the rational use of chemical fertilizers. Using field randomized block experiment, through the formulation N187.5 kg, P90.0 kg, K60.0 kg, N187.59 kg, P90.0 kg, N187.5 kg, K60.0 kg, P90.0 kg, K60.0 N157.5 kg kg and conventional P88.5 kg, K88.5 kg, N157.5 kg, P88.5 kg, N157.5 kg, K88.5 kg, P88.5 kg, K88.5 kg fertilizer rate comparison, the utilization rate of nitrogen, phosphorus and potassium fertilizer materials and the impact on production. Results show that the plastic film mulching cultivation under a g a, fertilizer than average wheat yield of 537.75 kg/hm2, increase 7.31%. Fertilizer use efficiency increased by 12.51%, 2.4% (2.4% nitrogen, phosphate, potash) conclusion: in longdong HanYuan or poor fertility zone production level, the formula ratio N12.5: P6: K4, using plastic film mulching cultivation, soil testing formula fertilization of wheat nitrogen fertilizer utilization rate was 37.4%, the utilization rate of 24.1% phosphate fertilizer, potash fertilizer utilization rate of 43.0%. Conventional fertilization of wheat nitrogen fertilizer utilization rate is 35.0%, utilization rate of 21.9% phosphate fertilizer, potash fertilizer utilization rate of 35.1%. Fertilizer compared with conventional fertilization, has significant stimulation effect, can significantly improve the utilization rate of fertilizer application should be promoted.
