Zhejiang Daxue xuebao. Lixue ban, 2015 通过温室盆栽试验，研究了在不同培养期内（1，2和4个月），不同磷肥（过磷酸钙、磷酸二氢钾、钙镁磷肥）及施磷量（P2O5 0.2，0.5 g • kg-1）对镉污染茶园土壤pH值、土壤有效态镉含量及茶树镉吸收累积量的影响.结果表明：钙镁磷肥的施加可有效提高茶园土壤的pH值，过磷酸钙和磷酸二氢钾对pH值的提高则不明显；过磷酸钙和钙镁磷肥均提高了 土壤有效态镉含量，且施磷量不同影响规律亦不同，而磷酸二氢钾对土壤有效态镉含量的影响不显著；茶树累积镉含量为根>茎>叶，根系对镉的富集能力极强 ...

Functional Ecology, Volume 40, Issue 6, Page 1725-1739, June 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

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 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Thermo‐responsive hydrogels based on poly(N‐isopropylacrylamide) (PNIPAM) are promising candidates for soft actuation, yet their practical applications are often constrained by sluggish thermo‐responsive kinetics and insufficient mechanical robustness.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT The development of high‐voltage aqueous zinc‐ion batteries (AZIBs) is primarily hindered by the lack of suitable cathode materials and electrolytes that can work in broad voltage windows. Herein, we propose a synergistic strategy that concurrently addresses these challenges through the integration of an amorphous vanadium oxyphosphate/graphene

Shuitu Baochi Xuebao, 2008 研究了不同施肥模式下红壤性水稻土中磷的分布及其有效性。结果表明,随团聚体粒径从大到小的变化,红壤性水稻土全磷含量在不同施肥模式下均表现出先上升后下降的趋势,在5～2 mm粒径团聚体中出现一个峰值;有效磷含量表现出先缓慢上升后迅速下降的特征,在5～2 mm粒径团聚体中出现一个大峰值;在施磷处理中,磷的有效率表现出先缓慢上升后迅速下降的特征,分别在5～2 mm和0.5～0.25 mm粒径团聚体中出现一个大峰值和一个小峰值,但在无磷处理中,磷的有效率表现出逐渐下降的趋势,只在0.5～0.25 ...

Functional Ecology, Volume 40, Issue 5, Page 1428-1442, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

长期磷肥不均投入下黄土高原土壤磷素有效性及与土壤性质关系分析
Shuitu Baochi Xuebao, 2019 由于科学施肥指导工作和生产实际的脱节，过量施用磷肥的现象普遍存在，进而造成大量磷素在土壤中累积。准确评价土壤中磷素的有效性是土壤磷素科学管理的基础。国际上梯度扩散薄膜技术（DGT）和传统方法相比可以更为准确地反映土壤中元素的生物有效性。以黄土高原具有代表性的60个土壤样品为研究对象，采用传统Olsen法和DGT技术评价多年磷肥投入不均条件下黄土高原地区土壤磷储量及其有效性现状，研究了DGT技术测定的DGT-P与全磷、Olsen-P之间的关系，并利用通径分析探究了土壤磷素有效性和土壤相关理化指标之间的关系。

Shuitu Baochi Xuebao, 2003 采用混合正交实验L(6×2)2设计,研究了藻类对土壤有效磷含量的影响,通过对实验结果进行统计分析,发现藻类能有效提高土壤有效磷含量,且不同的藻种间存在一定的差异。这揭示直接利用特定藻类能有效提高土壤可利用磷含量,又能增加土壤有机质,达到减少速效磷肥的施用和改善土壤肥力,这对保护环境、维持农业生态系统的可持续发展有重要现实意义。

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Driven by global energy transition and sustainability, sodium‐ion batteries (SIBs) have emerged as key alternatives to lithium‐ion batteries for low‐to‐medium energy storage, because of abundant sodium resources and low cost. However, their commercialization is hindered by the lack of anodes with high capacity, fast kinetics, and long‐term ...
