Abstract: ‘Xizhoumi No.25’ was used as the material to monitor the soil water dynamics of 0-60 cm in different growth stages of melon under four irrigation amounts（W1:7.5 mm;W2:15.0 mm;W3:22.5 mm;W4（CK）:30.0 mm）,the plant dry matter mass and melon fruit quality were measured,in order to explore the effects of irrigation amount on the yield,water use efficiency（WUE）,water consumption characteristics and quality of muskmelon in North China.The results showed that irrigation amount and water consumption were linear positive correlation,water consumption and yieldwere quadratic curve relationship,water consumption and WUE were linear negative correlation.The yield of W3 was the highest,which was 4.6%higher than that of CK.With the decrease of irrigation,WUE increased by 56.81%-84.81% compared with CK.With the increase of irrigation amount,the water consumption intensity of melon in each growth period decreased significantly,and the water consumption of soil storage was increased at the same time;the comprehensive quality evaluation index of muskmelon first increased and then decreased with the increase of irrigation water,and the quality of W2 was the highest,which was significantly higher than that of the control.Considering the yield,quality and water use efficiency,15.0-22.5 mm irrigation is suitable for thick skinned muskmelon in North China.
