【摘要】 根据南方土壤偏酸而北方土壤偏碱的特点，对南方珍稀阴生观叶花木组培苗的盆土基质进行了改良试验。结果表明：以盆土Ⅰ号、Ⅱ号为基质能够有效降低北方土壤的ｐＨ值，以普通自来水＋ ０２％ ＦｅＳＯ４＋ ０１％ （ＮＨ４）２ＳＯ４ 为浇灌水定期浇灌，可有效地防止盆土再碱化，使基质保持一定的酸碱度，从而使该花木在北方亦能生长好。更多还原

【Abstract】 To counter the characteristics that southern soil tends to acid and northern soil tends to base,potting mixture improvement experiment was conducted for rare southern shady leaf plant The results showed that no 1 and no 2 of potting mixture can reduce effectively the pH of northem soil,irrigation regularly with common tap water+0 2% FeSO 4+0 1% (NH 4) 2SO 4 can prevent the mixture from re solonization and deep its pH in a certain range更多还原
