Shuitu Baochi Xuebao, 2019 通过模拟试验及田间试验研究不同磷肥施用后对土壤磷有效性的动态变化和分布特点，以及玉米磷吸收和产量响应的影响。田间和模拟试验包括4个处理，分别为对照（不施磷肥）、MAP （磷酸一铵）、UP （磷酸脲）和AAP （水溶性聚磷酸铵）。模拟试验中，不同磷肥均提高土壤中有效磷含量，APP处理10-15 cm土层有效磷含量增加最多。在均匀的养分投入和管理水平下，3种磷肥品种均有土壤酸化效果，其中UP处理最为显著。田间试验中，玉米生长后期，APP处理的土壤有效磷含量在深层土壤分布较高，UP处理土壤pH较低 ...

Shuitu Baochi Xuebao目的菌根作为连接植物与土壤的桥梁，在土壤碳（C）库收支平衡中扮演着关键角色。菌根通过吸收土壤中的矿物营养物质以交换植物光合作用固定的C，同时也通过呼吸作用造成土壤C损失。尽管人们对菌根在土壤碳输入、分解和固持方面的作用已有较深入了解，但关于菌根对土壤呼吸的影响仍相对有限。方法采用网络排除法和比较法综述菌根对土壤呼吸的影响及其调控因子。结果通过网格排除法，有学者成功分离并量化菌根呼吸，发现其平均占土壤呼吸的16.8%。具体而言，丛枝菌根呼吸和外生菌根呼吸对土壤呼吸的贡献分别为18.4%（2.5%~32.0%
