摘要：为研究不同农林废弃物混合基质对崖柏扦插育苗的影响,筛选可替代草炭、成本低廉的环保型育苗基质,配制草炭+蛭石+珍珠岩(T_(1))、食用菌菌渣+蛭石+珍珠岩(T_(2))、炭化稻壳+蛭石+珍珠岩(T_(3))、食用菌菌渣+炉渣+锯末(T_(4))和炭化稻壳+食用菌菌渣+炉渣(T_(5))5种混合基质,采用随机区组试验设计,综合评价不同混合基质的优劣。结果表明:T_(3)容重最低,其次是T_(2),二者与其他混合基质差异显著;T_(2)的非毛管孔隙度显著大于T_(1),毛管孔隙度低于T_(1),总孔隙度低于T_(3);T_(2)的全氮、全磷、全钾、碱解氮、有效磷、基质含水量和pH最高,且与其他混合基质的大多数化学指标差异显著。不同混合基质的插穗生根率和生长发育指标的隶属函数值表现为T_(2)>T_(3)>T_(1)>T_(5)>T_(4)。灰色关联度数值较大的指标大多数是物理指标,位列前5位的是毛管持水量、全钾、田间持水量、最大持水量和总孔隙度,其中毛管持水量和全钾含量并列第一。总体上,食用菌菌渣+蛭石+珍珠岩的理化性质、插穗生根率及生长发育性状等优于其他混合基质。毛管持水量和全钾含量是影响崖柏插穗生根及苗木生长发育的主导因子;在插后短时期内,混合基质的物理性质对崖柏插穗生根率及苗木生长发育的影响大于化学性质。建议在崖柏扦插育苗时优先选择食用菌菌渣+蛭石+珍珠岩混合基质。
To screen environment?friendly seedling cultivation substrates which could replace peat and with less cost,we compared the effects of different agricultural and forestry residue mixed substrates on cutting propagation of Thuja sutchuenensis,in an experiment following randomized block design.There were five types of mixed substrates,including peat+vermiculite+perlite(T_(1)),edible mushroom residue(EMR)+vermiculite+perlite(T_(2)),carbonized rice husk(CRH)+vermiculite+perlite(T_(3)),EMR+slag+sawdust(T_(4))and CRH+EMR+slag(T_(5)).The results showed that the bulk density of T_(3)was the lowest,followed by T_(2),which significantly differed from other mixed substrates.The non?capillary porosity of T_(2)was significantly greater than that of T_(1),while the capillary porosity and the total porosity of T_(2)was lower than T_(1)and T_(3),respectively.T_(2)had the highest contents of total nitrogen,total phosphorus,total potassium,alkali?hydrolyzed nitrogen,available phosphorus,substrate moisture and the highest pH,which differed significantly from other mixed substrates in most chemical indicators.The membership function values of rooting rate and growth indicators of cuttings with different mixed substrates were in order of T_(2)>T_(3)>T_(1)>T_(5)>T_(4).Most indicators with larger grey relation values were physical indicators.The top five indicators were capillary water capacity,total potassium,field water capacity,maximum water capacity,and total porosity,with both capillary water capacity and total potassium content ranking first.In general,the physicochemical properties,rooting rate,and growth characteristics of cuttings under T_(2)were better than those of other mixed substrates.The capillary water capacity and total potassium were the main factors affecting rooting and growth of cuttings.At the early stage of cutting,the physical properties of mixed substrate had greater effect on rooting rate and ting propagation of T.sutchuenensis.
