    东方百合‘Sorbonne’无土栽培基质的研究

    Soilless culture media for Lilium ‘Sorbonne’

    • 摘要: 以目前国内百合切花生产上常用的基质(V(泥炭)∶V(珍珠岩)=7∶3)为对照,以环保可再生的农林废弃物椰糠等为原料,筛选适合东方百合 ‘Sorbonne’ 切花生产的无土栽培基质,以期减少或完全替代泥炭的应用。结果表明,基质3 (V(泥炭)∶V(蛭石)∶V(珍珠岩)∶V(麦秆)=5∶1∶2∶2)、基质4( V(泥炭)∶V(河砂)∶V(珍珠岩)∶V(玉米秆)=4∶1∶2∶3)和基质5( V(椰糠)∶V(蛭石)∶V(河砂)∶V(珍珠岩)=3∶2∶3∶2)的理化性质各项指标均在无土栽培基质的理想范围内,以其栽培的切花,在株高、叶片数、花蕾大小、根系发育、生物量积累以及切花的采后品质等方面,综合评价均优于对照,被认为是3种优良的百合切花无土栽培替代基质,其中基质3为最优。使用这3种替代基质用于百合切花生产,不仅可以在保证切花质量的同时减少泥炭用量,并可显著降低基质成本13%~47%。

       

      Abstract: In this study we selected Lilium ‘Sorbonne’ as a test species to investigate the possibility of using agricultural and forestry waste to replace peat as the growth medium. We used the mixture of V(peat)︰V(perlite)=7︰3 as a control, which is now commonly used for the production of lily cut flowers in China. The results showed that physical and chemical characteristics of the medium 3(V(peat)∶V(vermiculite)∶V(perlite)∶V(wheat straw)=5∶1∶2∶2), medium 4(V(peat)∶V(sand)∶V(perlite)∶V(corn straw)=4∶1∶2∶3) and medium 5(V(coir)∶V(vermiculite)∶V(sand)∶V(perlite)=3∶2∶3∶2) met the general requirements for soilless culture. The integrated performance, including plant height, number of leaves, size of flower buds, development of root systems, biomass accumulation and postharvest quality of the plants grown in the three media (3, 4 and 5) was significantly higher than that of the control. Plants grown in the medium 3 performed the best. Therefore, the three growth media can be used to reduce peat consumption and decrease the substrate cost by 13%-47%.
