探讨油松容器育苗中,用园林废弃物堆肥代替泥炭的可行性。采用随机区组试验设计,以油松容器苗为研究对象,研究不同比例的园林废弃物堆肥施肥量对油松容器苗出苗率和形态指标的影响。结果表明,在草炭、珍珠岩和园林废弃物堆肥三种原料组成的混合基质中,保持珍珠岩20%比例不变,当园林废弃物堆肥施肥比例低于40%时,油松苗能够达到出圃标准;而当园林废弃物堆肥比例≤20%时,油松苗的各形态指标与对照相比差异不显著,苗木质量较高。当采用园林废弃物堆肥代替草炭时,建议园林废弃物比例不高于40%。
The feasibility of replanting peat with garden waste composting in seedling raising of Pinus tabulaeformis was discussed. A randomized block design was used to study the effects of different proportions of garden waste composting fertilizer on seedling emergence rate and morphological index of Pinus tabulaeformis seedlings. The results showed that 20% of the perlite kept unchanged in the mixed matrix composed of three kinds of raw materials: peat, perlite and garden waste composting. When the proportion of garden waste compost was less than 40%, the pine seedlings could reach the standard When the proportion of garden waste composting was less than 20%, the morphological indexes of Pinus tabulaeformis seedlings were not significantly different from the control, and the seedling quality was higher. When using garden waste compost instead of peat, it is recommended that the proportion of garden waste not higher than 40%.
