肥料减施条件下水稻土壤有机碳组分对紫云英—稻草协同利用的响应
Shuitu Baochi Xuebao, 2017 研究紫云英与稻草不同利用模式在化肥减量条件下稻田表层土壤有机碳及其活性组分的差异，为合理利用有机物料调控土壤肥力提供参考。采用湖南省南县连续5 a（2011—2015年）大田定位试验，研究了减量施肥下洞庭湖地区紫潮泥双季稻田0-20 cm表层土壤总有机碳（TOC）、微生物量碳（MBC）、可溶性有机碳（DOC）、易氧化有机碳（EOC）和轻组有机碳（LFOC）对紫云英与稻草不同利用模式的响应。结果表明：与不施肥（CK）相比，单施化肥（F100）TOC、MBC、DOC、EOC和LFOC的含量均有显著上升 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Sodium‐ion capacitors (SICs) offer high energy and power density with long cycle life, but developing kinetically compatible electrodes remains challenging. This work developed a simple and sustainable strategy to synthesize homologous carbon electrodes from the inner shells of durian husks (ISDH) for high‐performance SICs.

Functional Ecology, Volume 39, Issue 12, Page 3504-3516, December 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Nitrogen (N) deposition strongly affects litter decomposition and nutrient release, thereby reshaping carbon cycling in terrestrial ecosystems. Although most studies have focused on above‐ground litter, the effects of N addition on fine root decomposition and their ...

Shuitu Baochi Xuebao, 2011 以中国科学院海伦农业生态实验站的长期定位施肥土壤为基础,研究长期施肥对黑土密度分组中碳和氮的影响。结果表明:氮肥能够增加土壤有机碳和全氮含量,但不如NPKOM效果明显。土壤中各组分有机碳含量的变化趋势为重组>游离态轻组>闭蓄态轻组,三者之间差异达极显著水平(p闭蓄态轻组>重组,且游离态轻组明显大于其它两个组分。NPKOM处理的闭蓄态轻组和重组组分中的有机碳浓度和全氮浓度大于其它施肥处理。碳氮比的变化趋势为游离态轻组>闭蓄态轻组>土壤>重组,重组和土壤中,NPKOM处理的碳氮比最低,CK处理的碳氮比最大 ...

New Phytologist, Volume 248, Issue 2, Page 690-705, October 2025.Summary Abscisic acid (ABA) induces stomatal closure, reducing transpirational water loss, a critical adaptation for agriculture under drought. However, ABA is often viewed cautiously as stomatal closure limits CO2 uptake for photosynthesis and growth.

Journal of Ecology, Volume 113, Issue 7, Page 1746-1759, July 2025.In forests dominated by large clonal plants, such as giant moso bamboo, drought can alter the allocation of newly assimilated C within the tissues of source ramet but may not affect its allocation among interconnected ramets or within plant–soil systems.

Functional Ecology, Volume 39, Issue 6, Page 1550-1566, June 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests store substantial amounts of soil organic carbon (SOC), but SOC stocks differ strongly between forest ecosystems dominated by arbuscular mycorrhizal (AM) or ectomycorrhizal (EcM) fungi.
