摘　　要：通过不同的补灌方式对压砂地西瓜进行了补水技术研究,结果表明,补灌技术对西瓜纵径和横径具有相同的影响效果,灌水定额和灌水方式对西瓜产量影响显著,灌水定额较灌水方式更为显著,而灌水次数无显著影响。三因素三水平的最优组合为滴灌方式、灌水定额为90 m3/hm2、灌水次数为4次。The paper researched water replenishing technology of gravel-mulched field watermelon by selected different supplied irrigation form.The result indicates： the lenishing technology have same effect for vertical and horizontal diameter of watermelon,irrigating water quota and supplied irrigation form have salience effect for yield,and irrigating water quota are more,but irrigation times no salience effect.The optimal combination of three factors and level are drip irrigation,irrigating water quota is 90 m^3/hm^2 and 4 times.It will provided theoretical base for water-saving supplied irrigation and highly active use of water for gravel-mulched field watermelon.
