油茶是一种主根长,侧根细而少的深根性树种,裸根苗造林常由于起苗时伤根过多,而影响成活率。我们于1977年3月1日在多本县多敬公社渠岩大队林场,用裸根苗造林50亩,成活率仅62％。为了提高造林成活率,我们按一年生油茶苗的根幅、根长情况,设计了一种“起苗打穴器”,在同年4月带土起苗, Camellia is a main root length, lateral root thin and few deep rootstocks, bare root seedling afforestation often due to the root cause of excessive injury, which affects the survival rate. On March 1, 1977, we paid tribute to the crews of the Quanyan Brigade in Duobian County on March 1, 1977, and used bare rooted seedlings for planting 50 acres with a survival rate of only 62%. In order to improve the survival rate of afforestation, we according to the annual root of tea seedlings root length, root length, designed a “seedling point”, in April the same year with soil pricking,
