一般培育苏铁多选在春夏两季,但在截取子株和茎干时,都会影响正在生长的母株。子株、茎干的伤口易受到感染,对各种条件都比较苛刻,往往达不到预想效果。本人经多年探索,发现秋冬季在温室内用粗沙来育植苏铁既安全又快捷,而且成型好。切取一般在11月下旬到2月进行。苏铁在这段时间内生长代谢缓慢,切割时不影响母株本身,而且子株和茎干的伤口较少受到细菌感染。切割母株旁的子株要注意少伤茎皮。培植多头铁树时,可选取观赏价值不高、高度在20厘米以上的苏铁球。根据情况 The general election of cycads in spring and summer multiple selections, but when intercepting sub-strains and stems, will affect the growth of the parent strain. Strain, stem wounds susceptible to infection, for a variety of conditions are more demanding, often fail to reach the desired effect. After years of exploration, I found autumn and winter in the greenhouse with coarse sand to cultivate cycad is safe and fast, and good shape. Cut generally from late November to February. Metabolism of cycads is slow to grow and metabolism during this period of time, cutting does not affect the mother plants themselves, and the wounds of daughter plants and stems are less susceptible to bacterial infection. Cut off the daughter plant next to the child should pay attention to less damage to the bark. Cultivate long Tieshue, you can choose ornamental value is not high, the height of more than 20 cm in the su-iron ball. Depending on the circumstances
