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。
Jiangsu Province, Su-wei-3, Su-wei-4, Su-bei-6 and Su-bei 7 were planted in the coastal areas of Jiangsu Province. March 22, April 1 and April 11) were mowed and the fresh and dry weight of young shoots was measured. The results showed that the total fresh weight of barley tended to increase gradually with the growing period, but the dry weight of leaves reached the highest value on March 12 and then decreased slowly. Therefore, barley seedling was used in Jiangsu coastal area The best cutting time is March 12. Among these 4 varieties, Su-wei-3 is an excellent variety of seedling barley in Jiangsu coastal areas.
