我单位有几盆盆栽苏铁,到5月叶片逐渐全部干枯。如此大的苏铁(至少有30年了)弃之不用实在可惜,但又如何挽救呢? 想来想去,我把几棵苏铁从盆中倒出,发现根毛死了很多,于是将枯叶全部剪去,根也修整一番,并用0.5%的高锰酸钾溶液浸泡2小时,然后用清水冲洗,栽进盆中,盆内装入细沙与土和锯末的混合物(锯末为腐熟的),比例是2:1:1,上盆后置于阴

The root is also trimmed and soaked in 0.5% potassium permanganate solution for 2 hours, then rinsed with water and placed in pots, the mixture was mixed with fine sand and soil and sawdust (sawdust is decomposed), the ratio Is 2: 1: 1, placed in the shade over the basin
