摘　　要：以江苏沿海地区推广种植的苏啤3号、苏啤4号、苏啤6号和苏啤7号为研究对象,在拔节孕穗期前5个时间点(3月2日、3月12日、3月22日、4月1日和4月11日)对其进行刈割试验,并对嫩苗的鲜质量和干质量进行测定。结果表明:大麦嫩苗总鲜质量随着生长时期的延长呈现逐渐增加的趋势,但叶片干质量在3月12日时达到最高值,后呈缓慢下降的趋势,因此苗用大麦在江苏沿海地区的最佳刈割时期为3月12号。在这4个品种中,苏啤3号是江苏沿海地区苗用大麦优良品种。The present study aimed to determine the optimal cutting time for barley seedlings for industrial use,and four barley varieties（ Supi 3,Supi 4,Supi 6,and Supi 7） were tested,which were planted in Jiangsu coastal area. At the jointing- booting stage,seedlings of the four varieties were cut on five different dates（ March 2,March 12,March 22,April 1,and April 11）,and their fresh and dry weights were measured. The results showed that the total seeding fresh weight rose gradually with increasing barley growth period,while the dry weight reached the highest value on March 12 th,then decreased slowly,indicating that March 12 was the optimal cutting time for barley seedlings that are used for industry in Jiangsu coastal area. Among all of the four tested varieties planted in Jiangsu coastal area,Supi 3 demonstrated to be an excellent barley variety whose seedlings have industrial use.
