繁殖苏铁,通常是采用先将从母本上切下的子株(即分蘖株)栽入纯净河沙中催根,再移植培养。这种办法比较繁琐。1988年3月,我们做了将子株直接栽入培养土中培养的试验,免去了先催根这一环节,获得成功。到88年5月,90％的子株都已长根发叶。具体做法很简单:先选择与子株大小相称的花盆,用瓦块垫好盆孔,装入厚1寸左右的煤渣和一层不太
The breeding of cycads is usually carried out by planting the sub-strains cut from the female parent (ie, the tillers) into pure river sand and re-culturing them. This approach is more complicated. In March of 1988, we did the test of transplanting the sub-strains into the culture soil directly, and succeeded in removing the part of promoting the root first. By May 1988, 90% of the offspring had long-rooted leaves. The specific approach is very simple: first select the size of the child-plant flower pots, pads with a good basin hole, into a thick 1-inch cinder and a layer not too
