摘　　要：为明确山东二季作区马铃薯早春三膜覆盖栽培模式下增施CO2的适宜浓度,本试验设计T1(0μL/L,CK)、T2(600μL/L)、T3(1200μL/L)、T4(1800μL/L)、T5(2400μL/L)5个增施CO2处理,测定不同处理下马铃薯块茎产量、商品薯率、干物质和淀粉含量。结果表明,CO2增施浓度在0~1800μL/L范围内,随着CO2浓度的增加,马铃薯块茎产量显著提高,商品薯率、干物质和淀粉含量稍有提高。T4处理的666.7m2块茎产量最高(4473.2kg,较对照增产25.4%,干物质含量最高(17.12%),比对照增加1.3%。CO2增施浓度为2400μL/L时,马铃薯块茎产量和干物质含量反而有所下降。To clarify the suitable application concentration of CO2 for three-film mulching cultivation of potato in the early spring under the double cropping mode of Shandong Province, the treatments of CO2 application concentrations such as 0(CK,T1), 600(T2), 1 200(T3), 1 800(T4), 2 400(T5)μL/L were studied. Then the tuber yield, commercial potato rate and the contents of dry matter and starch were determined. The results showed that the tuber yield increased significantly with the increase of CO2 application at the range of 0~1 800 μL/L, and the rate of commercial potato, the content of dry matter and starch also increased slightly. T4 treatment had the highest tuber yield and dry matter content. The tuber yield reached 4 473.2 kg per 666.7 m2 with the increment of 25.4% compared to the control, and the dry matter content was 17.12% with the increment of 1.3%. But the tuber yield and dry matter content of T5 treatment declined with the enhance of the CO2 concentration.
