摘　　要：测定分析了草炭、蛭石、珍珠岩、菇渣等单一基质及其不同配比复合基质的容重、总孔隙度、通气孔隙度、持水孔隙度、p H值及EC值等理化指标,并以章丘大葱为试材,比较不同复合基质对大葱幼苗生长的影响。结果表明,单一基质的综合理化指标难以完全满足大葱幼苗生长对基质综合性状的需求,复合基质优于单一基质;在参试的5种复合基质配方中,草炭∶珍珠岩∶蛭石=6∶3∶1(体积比)配比的大葱幼苗生长最佳。Some physical and chemical indicators such as density,total porosity,aeration porosity,water- holding pores,p H and EC value of peat,vermiculite,pearlite,mushroom residue and their compound matrixes in different proportions were analyzed in this article. And their effects on growth of Zhangqiu bunching onion seedlings were also studied. The results showed that the comprehensive physicochemical indexes of single matrix could not well meet the growth demands of bunching onion seedlings,while those of compound matrix were better. Among the 5 tested compound matrixes,the formula of peat∶ perlite∶ vermiculite as 6∶ 3∶ 1was the best for onion seedling growth.
