摘  要：
为了探索宁夏荒漠绿洲设施西瓜合理的灌水频率和灌溉定额,提高设施栽培西瓜的产量和品质,以及实现较高水资源利用效率。在西瓜不同生育时期耗水规律研究的基础上,以中卫设施西瓜为试验材料设置4个灌水频率梯度,对不同处理下的西瓜生长、产量和品质等进行测定分析。结果表明,从苗期到开花坐果期处理T1株高的增长率为388.05%,生长速率为2.06 cm/d,达到最大值;西瓜单瓜产量和西瓜终产量均以T2处理最大,分别为2.46 kg和18 889 kg/hm~2,其次是T1处理;T1处理维生素含量最大,为76.3 mg/kg;果实中心部位的含糖量和果实边缘部位的含糖量分别以处理T1和T2最大,说明适当的控水和水分亏缺使得西瓜产量有所降低,但是有利于西瓜品质的提高,特别是果实边缘处的含糖量。

摘  要：
In order to explore reasonable irrigation frequency and irrigation quota of Ningxia desert oasis facilities watermelon,improve yield and quality, and achieve higher water use efficiency, Zhongwei facilities watermelon were used as materials and four irrigation frequency gradient were set to measure and analyze watermelon yield and quality under different treatments based on the study of water consumption regularity of different growth stages on watermelon. The results showed that growth rate of the treatment T1 height from seedling to flowering and fruit setting stage was 388.05%, the growth rate 2.06 cm/d.melon single yield and final yield reached the highest under treatment T2, 2.46 kg and 18 889 kg/hm2 respectively, followed by treatment T1. Vitamin content under treatment T1 reached the maximum of 76.3 mg/kg. Sugar content of the central part under treatment T1 and that of the edge part under T2 reached the highest, indicating that adequate water control and water deficit decreased watermelon production but improved watermelon quality, especially the sugar content of the edges of the fruit.
