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 ...

, 2014 四川冬水田的发展史大致可分为清代的兴起与扩展,民国的继承与发展,新中国的改造与缩减三大阶段。水稻种植规模的大小、劳动生产率的高低、水利设施的多少均是影响冬水田发展的因素之一。以往提高农业产出的是改造冬水田的动因;现今提倡恢复冬水田又是出于其水利、生态湿地价值的考虑。冬水田作为一项大规模的水利工程,其之于四川农业 ...

Contribution of Different Processes in Wetland Soil N_2O Production in Different Restoration Phases of the Yellow River Estuary, China [PDF]
, 2014 采用时空替代法,选择黄河口生态恢复前后未恢复区(R_0)、2007年恢复区(R_(2007))和2002年恢复区(R_(2002))的芦苇湿地为研究对象,分析了生态恢复工程对湿地土壤N_2O产生不同过程与贡献的影响. 结果表明,尽管不同恢复阶段湿地土壤N_2O总产生量差异明显,但总体均表现为N_2O释放. 恢复区湿地土壤的N_2O产生量大于未恢复区.

Atomic‐scale understanding of interstitial‐strengthened high‐entropy alloys
Rare Metals, Volume 44, Issue 9, Page 6002-6014, September 2025.Graphic abstract Abstract Interstitial alloying has emerged as a powerful strategy to tune microstructure and microproperties of high‐entropy alloys (HEAs) due to the strong interaction of interstitials with constituent elements and crystal defects, which enables the development of advanced alloys with superior mechanical and functional properties. The

Trait‐Mediated Competition for Light Underpins Plant Diversity Loss Under Eutrophication
Global Change Biology, Volume 31, Issue 9, September 2025.Eutrophication often reduces plant diversity by making the ground layer darker, which reduces understory plants. In a natural alpine grassland, we added LED light beneath the canopy and saw diversity return across different nutrient treatments: with added nitrogen fertilizer, light mainly increased new species; with added phosphorus fertilizer, it ...

脲酶/硝化抑制剂对沿淮平原水稻产量、氮肥利用率及稻田氮素的影响
Shuitu Baochi Xuebao, 2019 添加氮素抑制剂是提高水稻氮肥利用率的有效途径之一。采用大田试验，探讨了氮素抑制剂（脲酶抑制剂N-丁基硫代磷酰三胺（NBPT）、硝化抑制剂3，4-二甲基吡唑磷酸盐（DMPP）及其组合）对沿淮平原水稻产量、氮肥利用率及稻田氮素的影响，旨在为优化沿淮稻田生态系统氮素养分管理，减少氮素损失提供科学依据。以"常糯1号"为供试材料，于2018年6-10月在安徽省怀远县（沿淮平原典型水稻种植区）进行试验。试验设5个处理：不施氮肥（CK）；尿素（U）；尿素+硝化抑制剂（U+DMPP）；尿素+脲酶抑制剂（U+NBPT ...
