不同时间割苗对再生大麦生物产量和籽粒功能成分的影响《不同时间割苗对再生大麦生物产量和籽粒功能成分的影响》

摘要：本文旨在研究不同时间割苗对再生大麦生物产量和籽粒功能性成分的影响。实验采用大麦主栽组（普通性高产大麦），选取9月5日、9月15日、9月20日、9月25日和10月1日作为割苗时间，进行割苗并评估大麦生长参数、籽粒抗氧化活性、籽粒可溶性糖含量、籽粒蛋白质含量以及籽粒碳水化合物含量。结果表明，早割苗（9月5日）使大麦穗长增加11.08%、叶片面积增加27.48%、籽粒抗氧化活性增加14.68%、籽粒可溶性糖含量增加3.78%、籽粒蛋白质含量增加15.07和籽粒碳水化合物含量增加4.46%。因此，早割苗有助于提高再生大麦生物量和籽粒功能性成分。

Introduction：Inrecentyears,theresearchofcropgrowthandyieldhasbecomeahotresearchtopicinthefieldofagriculture.Regenerativebarleyisanimportantcropinmanycountries,anditshigh-yieldgrowthandstrongresistancetohightemperatureanddroughtmakeitanimportantresourceforagriculturalproduction.Differentcuttingtimeshaveanimportantinfluenceontheyieldandqualityofregenerativebarley.Therefore,itisofgreatpracticalsignificancetostudytheeffectofdifferentcuttingtimesontheyieldandqualityofregenerativebarley.
