摘　　要：以MC670玉米为材料,在膜下滴灌条件下,通过CO_(2)溶水装置关键技术,研究玉米在不同生育时期滴施CO_(2)水溶液对其农艺性状、产量及籽粒营养品质的影响。结果表明:在玉米整个生育期内,与常规灌溉相比,滴施CO_(2)水溶液能够缩短玉米的生育进程,使生育期提前7 d,促进了玉米早熟;玉米的株高、茎粗、SPAD值都有所增加,对改善玉米植株生长有促进作用;产量、行粒数、穗长分别增长了21.94%、16.36%、8.26%,说明滴施CO_(2)水溶液具有显著的增产作用;玉米籽粒蛋白质、脂肪质量分数较常规灌溉分别增长了8.85%、27.78%,表明滴施CO_(2)水溶液有利于玉米籽粒蛋白质和脂肪的积累形成,可以提高玉米产量和改善玉米籽粒营养品质。In this experiment,MC670 was used as the variety material,and the effects of CO2 solution on agronomic traits,yield and grain nutritional quality of maize at different growth stages were studied through the key technology of CO2 solution device under the conditions of mulched drip irrigation.The results showed that during the whole growing period,compared with conventional irrigation,CO2 aqueous solution could shorten the growth process of maize under mulched drip irrigation,advance the growth period by 7 d,and promote early maturing.The plant height,stem diameter and SPAD value of maize were increased,which promoted the growth of maize plant.The yield,row grain number and panicle length increased by 21.94%,16.36%,8.26%,respectively,indicating that CO2 aqueous solution had a significant effect on increasing yield.Compared with conventional irrigation,the contents of protein and fat in corn grains increased by 8.85%and 27.78%,respectively,indicating that CO2 dripping was conducive to the accumulation of protein and fat in corn grains,and could improve the yield and nutritional quality of corn grains.
