摘　　要：以1年生对开蕨组培苗为试材,用以草炭、山皮土、园土、菌渣和珍珠岩为基质,按照不同比例配置的7种栽培基质[T1(CK1):草炭;T2(CK2):山皮土;T3V(园土)∶V(草炭)=2∶1;T4V(园土)∶V(山皮土)=2∶1;T5V(园土)∶V(山皮土)∶V(菌渣)=2∶1∶1;T6V(草炭)∶V(山皮土)∶V(菌渣)=2∶1∶1;T7V(草炭)∶V(珍珠岩)∶V(菌渣)=2∶1∶1]进行栽培适应性试验,研究了其在不同基质中的叶长、叶宽、叶面积和叶绿素的生长变化,并用隶属函数法综合评价。结果表明:T1的综合评价值最高,其次依次为T3、T6、T2、T5、T4和T7,综合草炭资源有限等因素,T3更适宜作为对开蕨组培苗幼苗的栽培基质推广应用。Taking one-year-old tissue culture seedlings of Phyllitis japonicaas the experimental material,the adaptability of P.japonicain the 7kinds of culture substrate were studied.The 7treatments were mixture of peat,hill-skill soil,garden soil,mushroom residue and perlite at the different volume ratio respectively,[T1（CK1）：peat,T2（CK2）：hill-skill soil,T3V（garden soil）∶V（peat）=2∶1,T4V（garden soil）∶V（hill-skill soil）=2∶1,T5V（garden soil）∶V（hill-skill soil）∶V（mushroom residue）=2∶1∶1,T6V（peat）∶V（hill-skill soil）∶V（mushroom residue）=2∶1∶1,T7V（peat）∶V（perlite）∶V（mushroom residue）=2∶1∶1].The experiment was conducted in terms of its leaf length,leaf width,leaf area and chloroplast pigment content in different substrate formulas,then evaluated them by subordinate function.The results showed that,T1 had the highest comprehensive evaluation value,followed by T3,T6,T2,T5,T4 and T7.However,T3 was considered as more suitable for substrate promotion of young tissue culture seedlings of Phyllitis japonica due to the limited resources of peat.
