摘　　要：试验立足宁夏气候变干变暖的趋势,以宁夏优势特色经济林树种"灵武长枣"为研究对象与材料,采用红外线辐射器控制模拟环境,测定单果重、果实纵横径、坐果率、果实糖含量及酸含量,揭示灵武长枣在日间气温升高与土壤干旱胁迫长期交互处理下坐果与果实品质的变化差异。结果表明,气温升高伴随干旱加剧灵武长枣果实的着色率、坐果率以及枣吊的吊果量有下降趋势,单果重有上升趋势,果实中糖酸比增加。In order to adapt the climate changes in Ningxia,i.e.,the drying and warming climate,taking Lingwu Long jujuba as material,using infrared radiation eqiupmant to control simulation environment,indices reflecting fruit quality were measured,such as weight and size of individual fruit,vertical and horizontal diameters,fruit setting rate,soluble sugar content and acid content under the interactive treatments of elevated and drough,to illustrate affecting mechanism of climate change to the fruit setting and fruit quality.The results showed that as the increase of temperature and drought stress,fruit coloring proportion,fruit setting rate and fruit yield decreased,while the weight of individual fruit,sugar-acid ratio increased.
