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 ...

沙角衣藻-杂交水稻实验体系中有效磷与磷酸酶活性变化关系的研究
四川大学学报. 自然科学版, 2004 对沙角衣藻 杂交水稻体系在含可溶性有效磷、磷矿石粉和无磷的三种培养基中有效磷浓度和碱性磷酸酶活性变化关系的研究结果发现:在全磷培养基中,随着有效磷含量的减少,体系中碱性磷酸酶活性随之升高;其中含磷矿石粉的无磷培养基中,加藻比无藻的培养基的碱性磷酸酶活性升高更突出;在无任何磷源的体系中,有藻的培养基碱性磷酸酶仍呈上升趋势,表明在缺磷胁迫下,藻和水稻都能产生碱性磷酸酶分解矿石磷.

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Transition metal‐based amorphous/crystalline (a/c) heterostructured catalysts have garnered significant attention due to their exceptional activity, stability, and cost‐effectiveness. However, the precise synergistic regulation of interfacial composition and phase states remains challenging.

Shuitu Baochi Xuebao, 2003 通过温室盆栽和大田试验研究旱作水稻在施用中量磷肥条件下,土壤水分对红壤中几种磷的含量和动态的影响。研究表明:土壤水分水平和采样时间对红壤全磷、有效磷、有机磷和不同形态的无机磷含量都有极显著的影响,且相互间的交互作用明显。栽种水稻后总体来说,土壤全磷、有机磷和O-P含量均有一定的提高,有效磷和Al-P、Fe-P、Ca-P含量则下降;土壤中不同形态无机磷含量为O-P>Fe-P>Al-P>Ca-P;大田和盆栽实验相比,在4种形态的无机磷、全磷和有机磷的排列顺序、演变趋势等方面基本一致,但有效磷则出现相反的结果,

Functional Ecology, Volume 39, Issue 10, Page 2889-2904, October 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract In the Southwest Australian Biodiversity Hotspot, the greatest plant species diversity tends to occur on the most phosphorus (P)‐impoverished soils. Many plant species in this P‐impoverished environment release root carboxylates that mobilise soil P which is a more ...

Plant nutrient‐acquisition strategies contribute to species replacement during primary succession
Journal of Ecology, Volume 113, Issue 4, Page 988-1003, April 2025.Pioneer species Hippophae acquires phosphorus and nitrogen mainly by ‘mining’ and N2‐fixing strategies and thus dominates in the beginning of primary succession. As soil nutrient availability increases with the mobilization of apatite‐P and input of N‐rich plant residues, Hippophae' strategies become less efficient than Populus's scavenging strategies.

Functional Ecology, Volume 39, Issue 2, Page 621-634, February 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Tropical forests are generally characterized by high species diversity and low soil phosphorus (P) availability. Although tropical plants have evolved adaptations to low soil P availability, we know relatively little about the strategies of different groups of species ...

Shuitu Baochi Xuebao, 2005 由于长期种植蔬菜，石灰性菜园土壤中的磷素在剖面中发生了分异，直接影响到其它营养元素的吸收和蔬菜的产量及品质。通过对不同植菜年限石灰性菜园土壤剖面磷素形态分级及其变异规律的研究，探讨了全磷、有效磷和无机磷不同形态的变异特征以及其磷素形态分布与其它土壤性质的关系。研究结果表明，石灰性菜园土壤耕层全磷、有效磷、无机磷与有机磷均比粮田富集强烈，有效磷源的无机磷形态含量与植菜年限呈明显的正相关，各形态无机磷含量的垂直分布与粮田存在显著关系，Ca2-P、Ca8-P、Fe-P含量为表层强烈富集，向下骤减的垂直分布特征。

Shuitu Baochi Xuebao, 2007 对棕壤26年长期定位试验的无机磷分级表明:长期施入有机肥或化学磷肥,除了Ca10-P含量在耕层减少外,其它各形态无机磷含量都有所增加;仅施N肥或不施肥,Al-P,Fe-P,O-P,Ca10-P含量均减少,Fe-P,Al-P,Cas-P,Ca2-P占无机磷总量的比例增加,而O-P,Ca10-P则下降了.各形态无机磷的剖面分布相似,均为先下降而后略微上升.相关分析和逐步回归分析表明,Ca2-P,Ca8-P,Al-P,Fe-P,O-P与速效磷之间达到1%的极显著水平,Ca10-P与速效磷之间达到5%的显著水平.
