为探究蘑菇渣堆肥添加基质对油松移植容器苗生长和苗木质量的影响,筛选出适合油松移植容器苗的最佳轻基质配比组合,以油松(Pinus tabulaeformis)1年生移植容器苗为研究对象,采用完全随机设计,选用蘑菇渣堆肥、珍珠岩、草炭为基质原材料,设置8种基质配方,在维持珍珠岩比例不变的情况下,以逐渐增加蘑菇渣堆肥比例的方式替代草炭,研究添加不同比例的蘑菇渣堆肥对油松移植容器苗生长和养分积累的影响。结果表明:蘑菇渣堆肥代替草炭进行油松移植容器苗培育是完全可行的,当蘑菇渣堆肥添加体积比例≤40%时,苗木在成活率、苗高、地径以及生物量等指标上与常用草炭处理无显著差异,且苗木体内部分养分含量显著高于对照,基质理化性质处于育苗合适范围内,苗木质量相对较高;而当蘑菇渣堆肥比例≥50%时,基质p H由微酸性变为碱性,苗木质量下降。因此在此试验条件下,培育油松移植容器苗推荐最佳基质配方为:35%草炭+25%珍珠岩+40%蘑菇渣堆肥。
In order to explore the effect of adding substrate of mushroom residue composting on the growth of seedlings and seedling quality of Pinus tabulaeformis plantlets, the best combination of light matrixes suitable for transplanting container seedlings of Pinus tabulaeformis was screened. One-year-old container seedlings of Pinus tabulaeformis The object of the study was to design a completely random design using mushroom compost, perlite and peat as substrate materials. Eight kinds of matrix formulations were set up. While maintaining the same proportion of pearlite, peat was gradually replaced by mushroom compost, The effects of adding different proportions of mushroom compost on the growth and nutrient accumulation of Pinus tabulaeformis seedlings were studied. The results showed that it was feasible to use mushroom compost instead of peat to cultivate the seedling of Pinus tabulaeformis plantation. When the compost volume of mushroom compost was less than 40%, the survival rate, seedling height, diameter and biomass of the seedling were commonly used Peat treatment no significant difference, and the part of the seedling body nutrient content was significantly higher than the control, physical and chemical properties of the substrate in the appropriate range of nursery stock, seedling quality is relatively high; and when the proportion of mushroom compost ≥ 50% Alkaline, seedling quality decline. Therefore, under this experimental condition, the best matrix formula recommended for cultivating Pinus tabulaeformis container seedlings is: 35% peat + 25% perlite + 40% mushroom residue composting.
