| 摘 要： | 为了更好地利用砧木抗性来综合防控苹果连作障碍，以平邑甜茶（Malus hupehensis Rehd.）、富平楸子 M. prunifolia（Willd）Borkh.]、八棱海棠（M. micromalus Makino）、新疆野苹果 M. sieversii （Le deb.）Roem.]、山荆子 M. baccata（Linn.）Borkh.] 为试材，探讨了不同苹果砧木对连作土壤中的酶活性、微生物以及酚酸类物质的影响。结果表明：以平邑甜茶为砧木的土壤磷酸酶活性最高，八棱海棠为砧木的土壤蔗糖酶活性最高，富平楸子为砧木的土壤脲酶活性最高；平邑甜茶为砧木的土壤真菌数量最低，富平楸子和平邑甜茶为砧木的土壤细菌数量较高，平邑甜茶为砧木的土壤细菌/真菌比值最高。从总酚酸含量来看，平邑甜茶为砧木的土壤酚酸含量最低，八棱海棠为砧木的土壤酚酸含量最高。综上，平邑甜茶为砧木的土壤真菌数量最少，土壤总酚酸含量最低，且相关土壤酶活性较高，说明其对连作土壤环境的改善效果最佳，更适合作为砧木综合防控苹果连作障碍。

| Abstract: | In order to better use of resistant rootstock to comprehensively prevent and control apple replant disease，the soil enzyme activity，microbial quantity and phenolic acids of 5 kinds of apple rootstocks，i.e. Malus hupehensis Rehd.，M. prunifolia（Willd）Borkh.，M. micromalus Makino.，M. sieversii（Ledeb.）Roem. and M. baccata（Linn.）Borkh. were analyzed in a short-term pot experiment. The results showed that soil phosphatase activity of M. hupehensis was the highest. Soil invertase activity of M. micromalus was the highest，and soil urease activity of M. prunifolia was the highest. The number of soil fungi of M. hupehensis was the lowest，and the number of bacteria of M. hupehensis and M. prunifolia was higher. M. hupehensis had the highest of bacteria/fungi ratio. From the aspect of total phenolic acid content，M. hupehensis had the lowest of total phenolic acid content，while M. micromalus had the highest of total phenolic acid content. In summary，M. hupehensis had the least number of soil fungi，and had the lowest of soil total phenolic acid content，and the related soil enzyme activities were higher. It showed that it was the best to improve the soil environment，and it was more suitable for the comprehensive prevention and control of apple replant disease. |
