过去繁殖苏铁,多待蘖芽分化出新叶后再掰下栽植,成活率虽高,但繁殖率低。八年前我取分蘖芽扦插,八个成活了五个。经过分析,原因是未成活的三个蘖芽个体小,内部贮存可供发叶长根的养分不足,实际上是两年生个体。成活的五个蘖芽都是三年以上的。后来又多次试插证明,蘖芽的个体需在两年以上、直径三厘米左右,这是一个基本的选芽标准。
In the past breeding of cycads, tillers and tiller bud differentiation after breaking off planted again, although the survival rate is high, but the reproduction rate is low. Eight years ago I took tillering bud cutting, eight survived five. After analysis, the reason is that the three non-surviving tiller buds are small and the nutrients stored inside the leaves are insufficient for root growth. In fact, they are two-year-old individuals. The five surviving tiller buds are more than three years. Then try again and again to prove that tiller bud individuals need more than two years, about three centimeters in diameter, this is a basic standard selection Bud.
