据巴西一年四季可以进行桉树扦插育苗的经验,结合我区的气候条件,我所于1986年12月—1987年2月在封闭式塑料棚内分三批进行刚果12号桉冬季扦插育苗试验,共扦插4591条,生根的有2956条,生根率64.4%,成苗率44.9%,现将试验小结于下。一、扦插育苗的方法(一)取插穗上午,从生长良好的6个月、10个月和19个月生(包括苗期)的幼树上剪取枝条,除去顶梢3—4cm 的幼嫩部分,剪成10—15cm 长的插条,顶端留两片半叶,其余的叶片剪去。将插条基都3—4cm 浸泡在0.3%高锰酸钾溶液消毒15min,取出后用清水冲洗。
According to Brazil’s year-round eucalyptus cutting propagation experience, combined with the climatic conditions in our district, I December 1986 - February 1987 in three-closed plastic shed Congo 12 Eucalyptus cuttings in winter trials , A total of 4591 cuttings, rooting of 2956, the rooting rate of 64.4%, seedling rate of 44.9%, now the test summary below. A cuttage nursery method (A) take cuttings morning, from well-growing 6 months, 10 months and 19 months of age (including seedlings) cuttings on young trees to remove the top 3-4cm of young Tender part, cut into 10-15cm long cuttings, leaving two half-leaf top, the remaining leaves cut off.
