摘要
随留茬高度增加 ,多年生黑麦草的相对生长速率和净同化率呈降低趋势。各延缓剂可显著降低多年生黑麦草的相对生长速率 。
The average relative growth rate (RGR) and net assimilation rate (NAR) were decreased with increasing of the stubble height . Plant growth retardant treatments did significantly decrease average RGR of perennial ryegrass while NAR did not changed.
