苏铁如莳养不当,往往会出现根烂、叶干甚至死苗现象。对这种苏铁,您不要急着丢弃,按下法处理,还可使其死而复生,重新焕发勃勃生机。一、修根重栽。当发现苏铁叶片干枯或将要干枯时,下部根肯定已全烂,失去了吸收功能。这时如果是寒冬,可能是受冻害所致;如果是春、夏、秋三季,那就是水肥不当造成根须死亡。应首先将苏铁球茎从盆中取出,抖去泥土,剪去枯叶,再用利刀把烂根腐茎一点点削去,一定要完全彻底,不留一点腐烂变质的部分。然后放在太阳下晒一两天,使创面发干后放入400倍多菌灵溶液中浸一下,捞出晾干。根据球茎大小,选用适当的花盆,内装净沙,将其栽入,浇透水。以后保持盆沙湿润即可,切不可湿度太大,以黄墒为好。花盆宜放在遮光度50％的荫棚下或稀疏的树荫下。为防蚂蚁等

And then placed in the sun for a day or two, so that the wounds dry into the carbendazim 400 times immersed in the solution, remove and dry. According to the bulb size, choose the appropriate flower pot, built net sand, planted it, drenched water. After the basin sand to keep wet can not be too humid to yellow soil moisture as well. Flower pots should be placed in shades of shade 50% shade or sparse shade. To prevent ants and so on
