近年来宁夏旱砂西瓜产区嫁接栽培迅速发展，但砧木品种繁杂。为筛选出适宜宁夏的旱砂西瓜嫁接砧木品种，选用10个南瓜砧木品种，观察了不同砧木对旱砂田西瓜生长、果实品质及产量的影响。结果表明，采用宁砧1号、宝根103、金城雪峰嫁接的旱砂西瓜折合产量较高，分别为42 470.37 、41 877.78、41 844.44 kg/hm2。宁砧1号嫁接的旱砂西瓜果皮硬度、果肉硬度、果实纵径最高，皖砧2号、宝根103、思状7号嫁接的旱砂西瓜果皮较厚，金城雪峰嫁接的旱砂西瓜果实中心可溶性固形物含量及总糖含量最高，宝根103嫁接的旱砂西瓜果实边缘可溶性固形物含量及总酸含量均高于其他砧木，宁砧1号嫁接的旱砂西瓜果实Vc含量均显著高于其他砧木。综合考虑认为，砧木品种金城雪峰、宝根103、宁砧1号对提高旱砂西瓜品质和产量的效果最好。

In recent years, the production region of grafted watermelon has developed rapidly in gravel-mulched fields in Ningxia, but rootstock varieties were complex. In order to select suitable rootstocks, 10 varieties of Cucurbita moschata stocks were selected to study their effects on growth, fruit quality and yield of watermelon in gravel-mulched field. The results showed that Ningzhen No.1, Jinchengxuefeng and Baogeng 103 grafted watermelon had higher equivalent yields which were 42 470.37 kg/ha, 41 844.44 kg/ha and 41 877.78 kg/ha, respectively. In gravel-mulched field, Ningzhen No.1 grafted watermelon had the highest peel hardness, fruit firmness and fruit longitudinal. Wanzhen No. 2, Baogen 103 and Sizhuang No.7 grafted watermelon all showed high fruit thickeness. Jinchengxuefeng grafted watermelon had the highest soluble solid content and total sugar content in the centre of the fruit, Baogen 103 grafted watermelon had the highest soluble solid content and total acid in the marginal parts of the fruit, and Ningzhen No. 1 grafted watermelon had the highest Vc content of the fruit. Based on comprehensive evaluation, the rootstock varieties Jinchengxuefeng, Baogen 103 and Ningzhen No.1 had the best effect on improving the quality and yield of watermelon in gravel-mulched field.
