摘要
选香菇渣、牛粪等原料复配,进行油松容器育苗试验,结果表明不同基质对油松1年生和2年生容器苗的生长有显著影响。在田园土中掺入一定比例的香菇渣和牛粪可以降低基质的容重,改善基质的物理性质,更有利于油松容器苗的生长。其中以54%田园土（体积分数,下同）＋23%香菇渣＋23%牛粪基质配方最佳,其次为77%田园土＋23%香菇渣、65%田园土＋35%香菇渣、65%田园土＋35%牛粪,其容重为0.79~0.88 g/cm3,比普通育苗土容重降低20%~28%。
The experiment on container seedlings of Pinus tabulaeformis was conducted to study the effects of nursery substrates on the growth of P.tabulaeformis container seedlings by adding the composition of waste material of shiitake mushroom production and cow dung.The results showed that the growth of one-year-old and two-year-old P.tabulaeformis container seedlings was significantly affected by the substrates.The substrate of 54% garden soil and 23% waste material of shiitake mushroom production and 23% cow dung was the best to the growth of P.tabulaeformis container seedlings because the substrate physical properties was improved due to a lower substrate bulk density,and then followed by 77% garden soil and 23% waste material of shiitake mushroom production,65% garden soil and 35% waste material of shiitake mushroom production,65% garden soil and 35% cow dung.The bulk density of all substrates was between 0.79 g/cm3 and 0.88 g/cm3 and decreased by 20% to 28%,compared with the normal nursery substrates.
