Apple replant disease (ARD) is common in apple production, which seriously affects the growth and development of apples. In this study, hydrogen peroxide with a bactericidal effect was used to treat the replanted soil, and the effects of different concentrations of hydrogen peroxide on replanted seedlings and soil microbiology were investigated in order to seek a green, clean way to control ARD. Five treatments were set up in this study: replanted soil (CK1), replanted soil with methyl bromide fumigation (CK2), replanted soil + 1.5% hydrogen peroxide (H1), replanted soil + 3.0% hydrogen peroxide (H2), and replanted soil + 4.5% hydrogen peroxide (H3). The results showed that hydrogen peroxide treatment improved replanted seedling growth and also inactivated a certain number of , while the , , and also became more abundant in relative terms. The best results were obtained with replanted soil + 4.5% hydrogen peroxide (H3). Consequently, hydrogen peroxide applied to the soil can effectively prevent and control ARD.
苹果再植病（ARD）在苹果生产中很常见，严重影响苹果的生长发育。本研究采用具有杀菌作用的过氧化氢处理再植土壤，研究不同浓度过氧化氢对再植幼苗和土壤微生物的影响，以寻求一种绿色、清洁的方法来防治ARD。本研究设置了五个处理：再植土壤（CK1）、用溴甲烷熏蒸的再植土壤（CK2）、再植土壤+1.5%过氧化氢（H1）、再植土壤+3.0%过氧化氢（H2）和再植土壤+4.5%过氧化氢（H3）。结果表明，过氧化氢处理改善了再植幼苗的生长，同时使一定数量的[此处原文缺失相关微生物名称]失活，而[此处原文缺失相关微生物名称]、[此处原文缺失相关微生物名称]和[此处原文缺失相关微生物名称]在相对数量上也变得更加丰富。再植土壤+4.5%过氧化氢（H3）处理效果最佳。因此，将过氧化氢施用于土壤可以有效防治ARD。
