摘    要:2010年研究了5个单粒播种夏玉米品种的收获期和后期籽粒脱水速率。研究结果表明:当籽粒黑色层形成、果穗苞叶彻底松散时,可作为夏玉米最佳收获期的标准。5个品种的平均日增产量为98.58~244.49 kg/hm2。在参试的5个品种中,以先玉335收获时的籽粒含水量最低,为19.85%;以登海662的后期籽粒平均脱水速率最大,达0.738%/d。

关 键 词:夏玉米  收获期  籽粒含水量  脱水速率

Abstract:The harvest date and seed dehydration rate in the later developmental period of single-grain-sown five summer maize varieties were studied in 2010.The results showed as follows: the day when the black layer of the grain appeared and the ear bract was completely loose could be used as the optimum harvest date of summer maize.The average daily gain yield of 5 varieties was from 98.58 to 244.49 kg/hm2.Among the tested 5 varieties,Xianyu 335 had the lowest moisture content in the grain at harvest stage,being 19...
Keywords:Summer maize  Harvest date  Seed moisture content  Dehydration rate
