摘　　要：为了提高柞园生产力水平,以2年生蒙古栎为试验材料,研究不同抚育次数对蒙古栎幼苗移栽成活率及生长量的影响。结果表明:抚育3次和4次的蒙古栎幼苗成活率及生长量均显著高于其他处理,成活率分别为89.67%、90.55%,分别比对照高54.67%和55.55%,但抚育3次与抚育4次之间成活率及生长量各指标(地上部分生物量、地下部分生物量、株高、根长、地径)均差异不显著。可见,抚育对提高柞苗移栽成活率及生长量有显著作用,且抚育3次即可满足生产需求。To improve the productivity level of oak garden,2-year old Q.mongolica was used as the test material to study the effects of different tending times on the survival rate and growth of Q.mongolica seedlings.Results showed that the survival rate and growth of Mongolian oak seedlings tending three times and four times were significantly higher than other treatment,the survival rates were 89.67%,90.55%,54.67%and 55.55%higher than the control,but the various indexes of survival rate and growth(above ground biomass,underground biomass,plant height,root length,diameter)of seedlings during the tending intervals were insignificantly different.It can be seen that tending plays a significant role in improving the survival rate and growth of tussah seedlings,and tending for 3 times can meet the production demand.
