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。
In order to make better use of rootstock resistance to prevent and control apple continuous cropping obstacles, Malus hupehensis Rehd., M.prunifolia (Willd) Borkh., M.micromalus Makino, , M.sieversii (Le deb.) Roem.] And M.baccata (Linn.) Borkh. The effects of different apple rootstocks on the activities of soil enzymes, microbes, Phenolic acids influence. The results showed that the highest activity of soil phosphatase was from Malus hupehensis, the highest sucrosease activity was from Malus bacutus as rootstock, the highest urease activity was from Malus bacari as rootstock, the lowest was from fungi Malus hupehensis, Fuping son and Pingyi sweet tea as the rootstock soil bacteria higher, the Pinglu sweet tea as the rootstock soil bacteria / fungi the highest ratio. From the total phenolic content, the content of phenolic acids in the soil of Pingyi sweet tea was the lowest, and the content of phenolic acids in the soil of the eight-sided begonia was the highest. In summary, the fungus Pingmu sweetpotato as the rootstock the least amount of soil total phenolic acid content and the highest soil enzyme activity, indicating that the continuous improvement of soil environment for the best, more suitable as a rootstock integrated control of apple continuous cropping obstacle.
