中文摘要	于20162017年在黄土高原半干旱区,利用新型开顶式气室( OTC),开展CO_2浓度升高与大气增温对马铃薯产量及品质的影响试验,研究CO_2浓度增加和温度升高对马铃薯发育过程、产量及品质的复合影响。结果表明:增温+CO_2浓度升高复合处理的叶片净光合速率比增温处理高36.3%,较对照高34.7%;马铃薯叶片的水分利用率表现为增温+CO_2浓度升高复合处理高于对照47.4%,高于单独增温处理43.4%;马铃薯实际产量和块茎蛋白质含量表现为CO_2浓度上升+增温处理高于对照12.9%、37.0%,高于单独增温处理59.7%、6.3%。在增温的同时增加CO_2浓度,使得马铃薯叶片净光合速率增加,水分利用率增大,有机物积累增多,经济产量提高。
英文摘要	In the semi-arid regions of Loess Plateau,OTC ( open-top chamber) was used to study the collaborative impact of increased CO_2 concentration and atmospheric warming on potato growth,yield,and quality from 2016 to 2017. The result showed that the net photosynthesis rate of leaves treated with elevated temperature and increased CO_2 concentration was 36.3% higher than that of the leaves treated only with elevated temperature only, and 34.7% higher than that of the control group from the inflorescence forming stage to the early stage of stem tuber enlargement. The water use efficiency of leaves treated with warming and increased CO_2 concentration was 47.4% distinctly higher than the control group and 43.4% higher leaves treated with only elevated temperature. The actual yield and stem tuber protein content of potatoes treated with elevated temperature and CO_2 concentration were 12.9% and 37.0%,significantly higher than that of the control group and 59.7% and 6.3% higher than that of the potatoes treated with only elevated temperature. The elevated temperature and CO_2 concentration did improve the potato net photosynthesis rate,water use efficiency,organic substance accumulation,and the yield.
