The effects of different slow release fertilizers with different release durations on cucumbers′yield，quality and nutrient use efficiency were studied by field trials.The results showed that:in condition of the same N，P，K application rates，compared to common compound fertilizers，cucumbers′yield with CRU and CRF increased 80%~157%，net earning increased 1 2786~7 0966 yuan/hm2，N，P，K utilization efficiencies increased 96~237 percentage points，but the effect of CRF B was best.The effects of different slow release fertilizers with different release durations on cucumbers′quality were different.Compared to common compound fertilizers，cucumbers′soluble sugar and protein with slow release urea and other fertilizers applications increased 030~103 g·kg 1 and 015~034 mg·（100 g） 1，nitrate contents reduced 683~3196 mg·kg 1，but the effect of CRF B on increasing cucumbers′quality was most striking.
