The results showed:90% treatment is the more suitable soil irrigation maximum index. Under 90% irrigation maximum treatment,fruit weight and quality were higher, prophase yield werehigher, water use efficiency werehigher in autumn andspring than that under 100% irrigation maximum.Keywords: cucumber; irrigation maximum; growth dynamics; yield; quality81 9 < :9 K i( 3 、 # Y
