, 2011 以畜禽废水沼气发酵液为磷回收对象,采用曝气沉淀结晶法磷回收工艺,对回收产物进行水溶性磷连续浸提试验和玉米盆栽试验,考察畜禽废水磷回收产物的磷素动态释放情况、玉米盆栽的肥效以及磷素利用情况。浸提试验表明,磷回收产物经6次浸提,水溶性磷的释放量呈缓慢下降的趋势,第6次与第1次相比只下降了1.42%,总释放量占总磷的57.97%,证明磷回收产物（RPP）具有良好的缓释性,作为肥料使用时不易被水淋失。盆栽试验表明,用RPP以不同比例代替磷酸一铵作为肥料对玉米均能起到显著的增产作用,最佳的质量替代比例为40 ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.

Organ‐specific ozone and nitrogen legacies strengthen substrate control over litter decomposition
Functional Ecology, Volume 40, Issue 8, Page 2548-2559, August 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Elevated tropospheric ozone (O3) and nitrogen (N) deposition are concurrent atmospheric changes that strongly influence terrestrial carbon cycling, yet their combined effects on below‐ground decomposition remain poorly understood.

Shuitu Baochi Xuebao, 2005 通过室内模拟培养和大豆盆栽土培生物模拟试验，研究了磷细菌溶解磷酸钙的能力及在北方石灰性土壤上施用磷细菌肥对土壤磷素转化的影响。试验结果表明：磷细菌菌株具有较强溶解磷酸钙的能力，磷酸钙的溶出率从第1天的2．80％提高到第8天的22．00％。在贫速效磷和富难溶性磷土壤上施用溶磷细菌肥有利于土壤中难溶态的Ca10-P和缓效态Ca8-P含量下降，促使土壤中Ca2-P和Al-P的含量增加，从而使土壤中有效磷含量增加。而对于富速效磷的土壤，无论施菌肥与否对土壤中各种形杰的无机磷绢分基本没有影响．

Shuitu Baochi Xuebao, 2011 选用天然风化煤和pH 3.63的酒厂废弃物酒糟、MV菌剂为活化剂,与PB、PC微晶化磷矿粉在30℃下发酵研究对枸溶性磷的活化效果。结果表明,MV菌剂促进微晶磷矿粉有效P的溶解,且磷矿粉变细解磷效果增强;酒糟、风化煤促进微晶磷矿粉有效磷的溶解;MV菌条件下的酒糟、风化煤有利于微晶磷矿粉的活化,有效磷含量在25d达最高;酒糟对微晶磷矿粉的活化效应2∶1>1∶1,25d枸溶性磷J6、J8、J2和J4分别比对照J净增长了1.63%,1.42%,1.32%及1.22%;MV菌条件下风化煤参与的发酵,25d处理F6、

Functional Ecology, Volume 40, Issue 8, Page 2590-2601, August 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Permafrost thaw is reshaping nutrient dynamics in boreal forests, but its impacts on tree nutrient limitation and functional strategies remain poorly understood. Clarifying these responses is crucial for predicting the response of boreal forests to climate change.

Journal of Ecology, Volume 114, Issue 8, August 2026.Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

Shuitu Baochi Xuebao, 2016 为探索长江上游稻油轮作系统减少农田磷素流失和有效提高磷肥利用率的最佳施肥模式，降低磷对水体富营养化的影响，采用长期田间定点试验并结合室内试验分析，研究了化肥配施猪粪和水稻秸秆还田对紫色土磷肥效应及磷素迁移的影响。结果表明：在常规作物施肥基础上配合施用有机肥，适当减少化学磷肥施用量，对作物产量没有显著的减产效应，且能在一定程度上减少农田磷素损失，提高磷肥利用率。水稻磷肥利用率总体表现为常规施磷量减20%+猪粪有机肥（MDP）＞常规施磷量减20%+秸秆还田（SDP）＞常规施肥+猪粪有机肥（MP）＞常规施肥 ...
