Abstract：Taking the cucumber variety Jinyou 4 as experimental material,the effects of different irriga-tion methods on the soil nitrate nitrogen content,soil enzyme activity,water and fertilizer utilization rate,yield and quality of cucumber were studied with two treatments of drip irrigation and furrow irrigation.The results showed that drip irrigation could increase the nitrate nitrogen content in 0~30-and 30~60-cm soil lay-ers,which were 183.87%and 80.50%higher than those of furrow irrigation respectively.Compared with fur-row irrigation,drip irrigation could significantly improve the soil invertase in each soil layer,urease and cata-lase activities in 0~30-cm soil layer,and alkaline phosphatase activity in 30~60-cm soil layer.Drip ir-rigation also could save water by 69.72%compared with furrow irrigation.The water use efficiency and fertil-izer partial productivity of drip irrigation treatment were 280.41%and 15.16%higher than those of furrow ir-rigation,respectively.Drip irrigation significantly improved the yield and quality of cucumber.The fruit solu-ble sugar,VC and soluble solids contents increased by 16.96%,19.64%and 19.14%respectively compared with furrow irrigation treatment.Therefore,drip irrigation had certain advantages in ensuring efficient utiliza-tion of nitrogen,improving soil microenvironment,increasing the utilization rate of water and fertilizer and the yield and quality of cucumber compared with furrow irrigation.
