摘要: 以平邑甜茶(Malus hupehensis Rehd.)幼苗为试材,在连作土盆栽条件下探讨了内生真菌球毛壳(Chaetomium globosmn)ND35菌肥对其生长和土壤环境的影响。试验共设3个处理:空白对照、连作土壤施加2%菌糠和连作土壤中施加2%球毛壳菌ND35菌肥(即菌糠 + ND35菌株)。结果表明:与对照相比,施加2%菌糠和ND35菌肥对平邑甜茶植株的生物量均有不同程度的促进作用,其中菌肥效果最为明显,施加2%菌肥的7月植株干、鲜样质量分别增加了71.9%、71.6%,9月增加了155.9%、153.1%,9月施加2%菌肥的效果比菌糠更加明显。施加2%菌糠和ND35菌肥均增加了土壤中微生物数量,且随着处理时间的增长,土壤细菌和放线菌数量均呈增加趋势,9月最多。其中施加2%菌肥增幅最高,7、8、9月细菌数量分别比对照增加了245.9%、89.1%、216.3%,放线菌数量分别比对照增加了68.7%、124.7%、131.1%。两种处理均增加了土壤酶的活性,8月的土壤脲酶、蔗糖酶和磷酸酶活性最高,其中以施加2%菌肥的土壤酶活性增幅最为明显。施加2%菌肥还增加了平邑甜茶植株的根系活力,7、8、9月分别比对照增加了59.0%、50.2%、20.2%。与对照和施加菌糠处理相比,球毛壳ND35菌肥可以更好地改善苹果连作土壤微生物区系(microflora),提高土壤酶活性,增加平邑甜茶幼苗根系活力和生物量。

Abstract: Effects of Chaetomium globosum ND35 fungal fertilizer on the replanted soil environment and Malus hupehensis Rehd. seedlings biomass were investigated in pot experiments. The experiment involved three treatments,including a control,the fungus chaff fertilizered into the soil which is carrierfungus chaff of Chaetomium globosum and Chaetomium globosum ND35 fungal fertilizer,a mixture of fungus chaff and strains,fertilizered into the soil with the concentration of 2%. Results showed that the fungus chaff and Chaetomium globosum ND35 fungal fertilizer application to replant soil significantly enhanced the dry and fresh weight of the seedlings compared with the control. And Chaetomium globosum ND35 fungal fertilizer increased in dry and fresh weight by 71.9% and 71.6% in July,155.9% and 153.1% in September than the control,respectively. The effects are more obvious in September. As the extension of the treating time,the quantities of soil bacteria and actinomycete were increased,and reached peak in September. Chaetomium globosum ND35 fungal fertilizer had a stronger effect. Compared with control,the quantity of soil bacteria in July,August and September increased by 245.9%,89.1% and 216.3%,respectively. The quantity of soil actinomycete increased by 68.7%,124.7% and 131.1% respectively. Both of the two treatments increased the activity of soil enzymes which increased with a subsequent decrease initially,and was the highest in August. The fungal fertilizer showed a significant increase to soil enzymes. The fungal fertilizer fertilizered into the soil significantly improved the root activity of Malus hupehensis Rehd.,and increased by 59.0%,50.2% and 20.2%,respectively in July,August and September. Compared with control and the fungus chaff,Chaetomium globosum ND35 fungal fertilizer can improve soil microflora,improve soil enzyme activity,increase root activity and biomass of Malus hupehensis Rehd. seedlings.
