In order to explore the effects of integration technology of water and fertilizer on yield and water and fertilizer use efficiency of facility cultivation of welsh onion,adopting drip irrigation fertilization and irrigation and fertilization of two different irrigation and fertilization methods, the test of drip irrigation fertigation technology effect on the cultivation of welsh onion. The results showed that fertilization techniques of drip irrigation could save water by 24.25% ~ 26.65%.And improve the welsh onion agronomic traits,increase the yield by 10.36%,improve the water production efficiency by 26.59%, increase the economic benefits by 12.9%;N,P,K fertilizer utilization rate were increased by 4.75,4.53 and 19.20 percentage points respectively,showing better balance of soil nutrient.
