摘要： 探讨海藻生物有机肥对减轻苹果连作障碍的效果，为生产中应用提供理论依据。以苹果砧木新疆野苹果[Malus sieversii (Ledeb.) Roem]为试材，盆栽条件下，研究加入0.5%、1.0%和1.5%的海藻生物有机肥对苹果连作土壤环境和新疆野苹果幼苗的影响。结果表明，海藻生物有机肥能显著提高新疆野苹果幼苗的干鲜重。海藻生物有机肥的施入提高了连作土中细菌、放线菌数量，降低了真菌总量，同时，还降低了连作土中主要酚酸类物质的含量。因此海藻生物有机肥有减轻苹果连作障碍的作用。

Abstract: The purpose of this study was to investigate the mechanisms and effects of seaweed biologic organic fertilizer on the plant growth of Malus sieversii (Ledeb.) Roem. seedlings under replant conditions. Before the Malus sieversii (Ledeb.) Roem. seedlings were planted in pots, the seaweed biologic organic fertilizer was added to pots in four rates: 0, 0.5% , 1.0% and 1.5% of seaweed biologic organic fertilizer per kilogram of replant soil. The results showed that seaweed biologic organic fertilizer applied to replant soil obviously enhanced the dry and fresh weight. The bacteria and actinomyces population quantities were increased by seaweed biologic organic fertilizer was added to soil, and the amount of fungi was decreased. Moreover, seaweed biologic organic fertilizer decreased the total of phenolic acids. So the seaweed biological organic fertilizer can reduce the apple continuous cropping obstacle.
