摘　　要：本文收集了64篇文献,通过Meta分析,对育苗基质中添加农林有机废弃物对于幼苗生长的影响进行定量评估,为有机废弃物的资源化利用提供理论依据。结果表明,来源于林业的有机废弃物显著改善了基质的总孔隙度(+10%)、通气孔隙度(+20%),提高了基质的全氮(+103.29%)、碱解氮(+59.59%)以及速效钾(+114.5%)的含量,促进了幼苗的根系(根系活力+28.01%)和地上部的生长(生物量+35.50%);经过生物处理的有机废弃物显著提高了基质的养分含量,增强了幼苗的根系活力(+43.5%),改善了叶绿素水平(+18.52%),提高了幼苗地上部生物量(+26.54%)。基质中添加林业废弃物或将其经过生物处理后使用可以显著促进幼苗的生长,实现废弃物的资源化利用。The effects of adding organic waste from agriculture and forestry on seedling growth were quantitatively evaluated by the Meta-analysis based on 64 literature. The results show that the organic waste from forestry could significantly improve the total porosity(+10%), aeration porosity(+20%), total N content(+103.29%), alkali hydrolyzed nitrogen content(+59.59%) and available potassium content(+114.5%) in the substrates, and increase root activity and shoot biomass by 28.01% and 35.50% respectively. Organic waste after biological treatment could significantly increase the nutrient content of substrate, thus enhance the root activity, chlorophyll concentration and shoot biomass in the seedlings by 43.5%, 18.52% and 26.54%respectively. In conclusion, adding forest waste or organic waste after biological treatment into the matrix could significantly promote the growth of seedlings and realize the resource utilization of waste.
