以江苏省国营大沙河果园为代表 ,查明淮北黄泛沉积区果园土壤肥力现状。结果表明 :土壤有机质和全N含量极低 ;速效K和速效P偏低 ;有效B、Fe、Mn严重不足 ;有效Zn部分不足。讨论了传统果园管理制对土壤肥力的影响。提出了以发展果园生草管理制为主的提高果园土壤肥力的对策 Taking the state-owned Dashahe Orchard as the representative, the status of soil fertility of orchards in the Huangfan sedimentary region of Huaibei was identified. The results showed that the contents of soil organic matter and total N were very low; the available K and available P were low; the available B, Fe and Mn were not enough; the available Zn was not enough. Discuss the impact of traditional orchard management system on soil fertility. The countermeasures to improve the soil fertility of orchards are put forward based on the development of grassland orchard management system
