沙埋苏铁繁殖法在《中国花卉盆景》上介绍过,有的作者提到“沙埋苏铁子球,大些的子球成活率高些,但只有1厘米或稍嫩些的子球成活率低或培育时间较长。”我认为此提法有待商榷。我通过十几年的实践证明:不论苏铁球径大小(包括直径1厘米左右的子球),经沙埋、围径沙埋,苏铁生根长叶比常规露球栽培至少快2～3倍。方法简便,使用新鲜河沙无需消毒处理。只要球径底部消毒处理好,就不会出现烂球现象。我是这样操作的:一、围茎沙埋:盆栽苏铁出现叶片变黄或受
Sand buried in the law of iron cultivation in the “Chinese flower bonsai” on the introduction, and some authors mentioned “buried in the iron sub-ball of sand, larger sub-ball survival rate higher, but only 1 cm or slightly more sub-ball survival Low rate or longer incubation time. ”" I think this formulation is open to question. Through more than 10 years of practice, I have proved that regardless of the size of the cycads (including the balls of about 1 cm in diameter), burial in sand and sand in the surrounding sand gives the cycads the root and leaf of the cycads at least 2 to 3 times faster than conventional dew-cultivation. Method is simple, the use of fresh river sand without disinfection. As long as the bottom of the ball diameter disinfection, there will be no bad ball phenomenon. I am doing this: First, surrounded by stem sand buried: leaves of potted cycads turn yellow or by
