摘要(Abstract)：
以香菇菌糠、木耳菌糠、泥炭、谷壳、大田土和缓释肥配制育苗基质,开展不同配方基质对榧树Torreya grandis容器苗生长的影响研究。结果表明:不同配方基质对榧树的容器苗的苗高、地径和生物量影响有显著差异,木耳废菌糠复合基质、香菇菌糠复合基质培育的榧树苗木平均质量指数均优于泥炭基质,其中以木耳菌糠、谷壳、大田土体积比为60∶20∶20的基质配方(A2)的苗高、地径、根系生长最优;菌糠复合基质大幅降低了育苗成本,其中木耳废菌糠复合基质仅是泥炭复合基质成本的35.8%。菌糠复合基质实现了食用菌废弃物循环利用,并大幅降低了榧树育苗成本,提高了苗木质量。
The seedling substrates were prepared with the fungal residue, mushroom residue, peat, chaff, field soil and slow-release fertilizer, and the effect of substrate with different formulas on the growth of container seedlings of Torreya grandis was carried out. The results showed that:(1) Different substrates with different formulas had significant effects on seedling height, ground diameter and biomass of the container seedlings of Torreya grandis. The average quality index of Torreya grandis seedling cultivated by the compound substrate with fungal residue or with mushroom residue was better than that of peat substrate. Among them, the compound substrate formula A2 with the volume ratio of 60∶20∶20 for fungal residue, chaff and field soil was the best for the seedling weight, ground diameter and root growth.(2) The compound substrate with fungal residue greatly reduced the cost of seedling cultivation, and the cost of compound substrate with fungal residue was only 35.8% of the cost of peat compound substrate. The application of mushroom residue substrate realized the recycling utilization of mushroom residue, greatly reduced the seedling cultivation cost and improved the seedling quality of Torreya grandis.
