1965年我们采用了次生枝育竹苗60万株,平均成活率达20%,高的一畦成活率达66%。一丛散生撑篙竹可以取得次生枝150—200株,按育苗成活率20%算,可得苗1400株,其中约有1/3每株抽笋3—4条,可分笋定植,一年一亩撑篙竹可繁育1800株,可供40亩造林用苗。逢雨栽植,成活率一般达90%以上,可常年造林。现将次生枝育苗的方法介绍如下: In 1965, we adopted 600,000 secondary bamboo shoots, with an average survival rate of 20% and a high survival rate of 66%. A bunch of scattered support bamboo can obtain secondary branch 150-200 strains, according to the nursery survival rate of 20% count, available 1400 seedlings, of which about 1/3 of 3-4 per plant shoots, can be divided shoots colonization, a year A mu Zhuzhu bamboo breeding 1800, for 40 mu afforestation seedlings. Rain planting, the survival rate of more than 90% of the general, can reforestation year round. Now the method of secondary branch nursery introduced as follows:
