摘　　要：为探索出鲁西南二季作区早春三膜栽培模式下增施CO2气肥对马铃薯生长发育的影响,设计CK(不施CO2)和增施CO2(液化气燃烧法)2个处理。每隔6 d收获一次,随机收获3株,测定单株马铃薯株高、株幅、叶面积、植株鲜重和干物质率、块茎鲜重和干物质率等指标的动态变化。结果表明,随着增施CO2量的增加,地上部生物量和叶面积比CK增长显著;单株块茎增产极显著,平均增幅达43.3%。To explore the effects of CO2 for three-film mulching cultivation of potatoes in the early spring under the potato double cropping mode of Southwest Shandong Province.Two treatments,CK(without CO2)and CO2(liquefied gas combustion method),were designed in this experiment.Three plants were harvested randomly every six days.The dynamic changes of individual potato plant were determined,including plant height,plant width,leaf area,fresh weight and dry matter rate of aboveground part,fresh weight and dry matter rate of underground tuber.The results showed that the above ground biomass and leaf area increased significantly compared with CK,with the continuous application of CO2,and the yield of tuber per plant increased significantly,with an average increase of 43.3%.
