笔者从市场上买回一段径围45cm的苏铁茎块,虽无根无叶,经四年栽培养护,现已羽叶油绿,姿态奇特,惹人喜爱,极富观赏效果(见右上图)。一、栽培:先将买回的茎块纵劈成两半,分别把茎块埋入土中,浇透水置蔽荫处。此后以喷水为主,保持土壤湿润,切勿多浇水,否则茎块易烂。一般半年左右即可生根萌叶。如未见萌叶,只要茎块没有烂,就不要抛弃,可在第二年春重新复种一次,茎块仍然会再生根长叶。如能适时少量喷施磷酸二氢钾和硫酸亚铁,长出的叶子会逐渐深绿而有光泽。二、养护:无根叶茎块培养成的苏铁,与正常生长的苏铁养护相同,叶片短小比叶片肥大者更富观赏性。要促使叶片短小须注意三点:①新叶萌发时扣水,且避免雨淋,使茎块处于 I bought from the market for a period of 45cm around the size of the cycads stems, although no root without leaves, after four years of cultivation and conservation, is now feather oil green, peculiar attitude, attractive, highly ornamental effect (see the upper right). First, the cultivation: First buy back the stem split longitudinally split in half, respectively, stems buried in the soil, water and water to shade. Since then to water-based, keep the soil moist, do not water, or stem rot easily. Generally six months or so rooted Meng leaves. If you do not see Meng leaves, as long as the stem is not rotten, do not give up, you can re-seed the second spring, the stem will still regenerate roots and leaves. If timely spraying a small amount of potassium dihydrogen phosphate and ferrous sulfate, the leaves grow gradually dark green and shiny. Second, the conservation: stems without root stalks cultured into cycads, and the normal growth of the conservation of the same cycads, leaves shorter than the foliage hypertrophy more ornamental. To promote the short leaves must pay attention to three points: ① new leaves when the water buckle, and avoid rain, the stems in
