%X 依托2012年布设在陇中旱农区的田间定位试验，在2014-2015年研究4种土壤培肥模式［培肥（NA）、猪粪（SM）、秸秆（MS）、猪粪+化肥（SC）］对粮饲兼用玉米纤维素质量分数和积累率，粗蛋白质量分数及产量的影响。结果显示，玉米各生育时期干物质累积量、籽粒和饲草产量均SC>SM>MS>NA。2014年和2015年，与NA比较，SC处理籽粒和饲草产量分别提高67.24%、49.40%和78.69%、55.09%。随着玉米生育进程的推进，粗蛋白质量分数降低，酸性洗涤纤维（ADF）和中性洗涤纤维（NDF）质量分数增加，玉米各生育时期纤维素质量分数及积累率各处理表现为SCSM>MS>NA。可见，猪粪与化肥相结合提高粮饲兼用玉米产量，降低纤维素质量分数，是有利于陇中旱农区粮饲兼用玉米高产优质可持续生产的土壤培肥模式。<br>The effects of four soil amendments,including no amendment(NA),swine manure(SM),maize straw(MS),swine manure +chemical fertilizer(SC),on fiber mass fraction and accumulation rate,crude protein mass fraction and yield were studied from 2014 to 2015.The research was conducted in a long-term experimental field in Dingxi,Longzhong area in 2012.The main findings were as follows:dry matter accumulation at growth stage,maize grain and forage yield under treatments were SC>SM>MS>NA.Compared with NA,the grain and straw yield in SC were improved respectively by 67.24%,49.40% and 78.69%,55.09% in 2014 and 2015.During mature period of maize,crude protein decreased,acid detergent fiber(ADF) and neutral detergent fiber(NDF) increased，fiber accumulation and fiber accumulation rate at growth stage of maize under treatments were SCSM>MS>NA.Therefore,the application of swine manure in combination with chemical fertilizer was more suitable for sustainable cultivation of grain and feed maize in dry farming areas of central Gansu in China.It was necessary to improve maize grain and forage yield as well as quality to increase sustainable maize production.
