Abstract In order to explore the suitable cultivation and irrigation pattern for producing watermelon〔Citrullus lanatus（ Thunb.）Matsum. et Nakai〕with stable yield and superior quality in Northwest China greenhouse，this study took the local traditional irrigation experience as the contrast， and set up the following 2 treatments：T1 controlling the various growth stages for the lower limit and the upper limit of soil relative moisture contents；T2 controlling the upper limit of soil relative moisture content. These 2 treatments were used to study the responses of watermelon yield and quality to different irrigation patterns. The results showed that during stretch tendril and maturing periods， controlling the lower limit（70%， 65%） of soil relative moisture content could significantly improve water use efficiency whithout distinquishly reducing watermelon yield. By controlling the lower limit and the upper limit of soil relative moisture contents， the water use efficiency increased 21.85% than the contrast. At the same time， controlling soil relative moisture content could significantly improve the content of soluble sugar content， which was the major substance affecting watermelon flavor.
