东方百合品种‘西伯利亚’切花生产中替代泥炭的基质研究

以东方百合品种‘西伯利亚’（‘Siberia’）为试材，研究了在混配基质中用麦秆、玉米秆、椰糠、菇渣、豆荚等5种有机废弃物替代泥炭作为栽培基质的可行性。结果表明，5份泥炭︰2份珍珠岩︰1份蛭石︰2份麦秆、4份泥炭︰2份珍珠岩︰1份沙子︰3份玉米秆、2份珍珠岩︰2份蛭石︰3份椰糠︰3份沙子（均为体积比）等3种混配基质的各项理化指标均在无土栽培基质的理想范围内，用其栽培的百合，生长发育综合表现优于目前生产上常用的含70%泥炭的基质，其中又以4份泥炭︰2份珍珠岩︰1份沙子︰3份玉米秆的基质最优。

Research on Substrates as Peat Substitute for Cut Flower Production of Oriental Lily

In order to reduce the use of peat as main substrate in lily cut flower production in China，Lilium ‘Siberia’ was used to investigate the possibility of using organic waste，including wheat-straw，corn stalk，coir dust，mushroom residue and bean pod as peat substitutes. The results indicated that the physical and chemical characters of three mixed substrates as V（peat）︰V（perlite）︰V（vermiculite）︰V（wheat-straw）= 5︰2︰1︰2，V（peat moss）︰V（perlite）︰V（sand）︰V（corn stalk）= 4︰2︰1︰3 and V（perlite）︰V（vermiculite）︰V（coir dust）︰V（sand）= 2︰2︰3︰3 meet the general requirements for soiless culture of lily. The integrated performance of the plants grown in the above mentioned 3 substrates during the growth and development was significantly better than the control，which is mainly employed in the present production of lily cut flower with as much as 70% of peat included. Plants in the treatment of V（peat moss）︰V（perlite）︰V（sand）︰V（corn stalk）= 4︰2︰1︰3 presented the best.
