| 摘 要： | 以生产上常用的苹果砧木平邑甜茶幼苗为试材,在苹果连作土盆栽条件下研究了棉隆(四氢化–3,5–二甲基–2H–1,3,5–噻二嗪–2–硫酮)熏蒸加海藻菌肥对幼苗生长以及土壤环境的影响。试验结果表明,与连作土对照相比,棉隆熏蒸、连作土+海藻菌肥对平邑甜茶幼苗的生长均有不同程度的促进作用,二者组合使用效果最为显著;棉隆、海藻菌肥、棉隆+海藻菌肥均提高了平邑甜茶幼苗根系CAT、POD、SOD活性,其中棉隆+海藻菌肥的效果最明显;棉隆+海藻菌肥提高了幼苗根系总长度、根表面积、根体积、根尖数;海藻菌肥显著增加了土壤中细菌与真菌的数量,棉隆+海藻菌肥增加了土壤中细菌数量以及土壤中细菌与真菌的比值。棉隆熏蒸+海藻菌肥能更有效地减轻苹果连作障碍。

| Abstract: | To clarify the effects of soil fumigation with dazomet（3,5-dimethyl-1,3,5-thiadiazinane- 2-thione）and seaweed biologic fertilizer on the young apple（Malus hupehensis Rehd.）seedlings biomass and soil microbial quantity under replant conditions. The results showed that compared with the control，dazomet fumigation and seaweed biologic fertilizer all increased the apple seedlings biomass，the effect of the combination was best. Compared with the control，dazomet fumigation，seaweed biologic fertilizer and the combination improved the activities of CAT，POD and SOD in root of the apple seedlings，the effect of the combination was more obvious. Compared with the control，the combination improved total root length，surface area，volume and tips of apple seedlings. Seaweed biologic fertilizer significantly increased the number of bacteria and fungi in the soil than the control，respectively. The combination increased
the number of bacteria and the ratio of bacteria and fungi in the soil. The combination of dazoment fumigation and seaweed biologic fertilizer could more effectively reduce the apple replant disease. |
