栽培铁树30多年了,养了近百株铁树,然而铁树中的珍品——多头铁讨,我却一棵也没有。遗憾之余,我便开始试验培植多头铁树。4年间先后牺牲了9棵铁树,终于有4种方法获得了初步成功、方法一选一棵根部长有3～4个幼仔的苏铁,把老根从底端锯掉(最好初春萌芽前锯),注意不要损伤幼仔。把锯下的树身风干4～5天,然后埋入土中一半,浇透水。到了 Cultivation of iron trees for more than 30 years, raising nearly a hundred trees, however, treasures in the iron tree - bull for more, but I have no one.
