不同基质配比对百合切花品质的影响

The Different Ratio of Matrix Influence on the Quality of Cut Lily

为了寻求减少百合无土栽培对泥炭资源的依赖和降低生产成本,测定分析6种不同配比基质的容重、总孔隙度、通气孔隙度、毛管孔隙度、含水量、pH、电导率等理化指标,并对栽培在6种不同基质中百合切花的主要农艺性状进行分析。结果表明:在百合适宜生长的范围内,基质容重和pH越小、总孔隙度和通气孔隙度越大,百合生长越好。试验中,T1(泥炭∶珍珠岩=3∶1)和T3(泥炭∶珍珠岩∶食用菌渣=2∶3∶2)2种配比是百合栽培的最佳配方基质;CK(纯泥炭)前期对茎高有影响,且考虑泥炭是一种短期内不可再生的稀缺的资源,因此,不宜作百合切花的基质;T5(泥炭∶蛭石∶稻壳=3∶5∶2)配比基质不能用于百合切花生产。

The author tested and analyzed some physical and chemical indicators such as bulk density, total porosity, aeration porosity, capillary porosity, water content, pH value and conductivity in 6 different ratio matrices in the experiment, in order to reduce the dependence on peat resources and the production costs in lily soilless culture. The author also analyzed the main agronomical characters of cut lily which were cuhured in 6 different matrices. The results showed that in the suitable range for the lily＇ s growth, the smaller the matrix bulk density and the pH value were, as well as the larger aeration porosity and capillary porosity were, the better the lily grew. In this experiment the two ratio T1 （peat： perlite=3：l） and T3 （peat： perlite： mushroom residue=2：3：2） were the best formula matrix for lily cultivation; CK （pure peat） could influence on the stem height in the early age and the author considered that the peat was a non-renewable scarce resource in short term, so it was not suitable to be the matrix for cut lily; T5 （peat： vermiculite： rice hulls=3：5：2） ratio matrix could not be used in cut lily production.
