摘　　要：在河南省柞蚕生产区利用植物生长调节剂调控柞树叶片生长发育,为一化性柞蚕区壮蚕用叶提供适熟叶。试验结果:植物生长调节剂可使柞树叶片延迟老化20d以上,一年生柞园壮蚕期单位面积可用叶量是冬季砍伐后火芽的1倍以上,且随着柞树树龄的增长而逐年增加。Plant growth regulator was used to regulate the growth and development of the oak tree to provide mature leaves for grown silkworms in univoltine tussah rearing area. Results show that plant growth regula tot can delay the aging of oak tree leaves by over 20d,and the available leaves per unit area for grown silk worms in univoltine tussah rearing gardens was over one time of that of buds after the oak tree was chopped down in winter, which also increased year by year with the aging of the oak tree.
