Factors that shape large‐scale gradients in clonality
Journal of Biogeography, Volume 50, Issue 5, Page 827-837, May 2023., 2023 Abstract Aim Many plant species reproduce clonally. However, ecologists still have much to learn about the factors that shape large‐scale patterns in plant clonal growth and reproduction, especially in the southern hemisphere. We addressed this knowledge gap by quantifying relationships between reproductive mode and a suite of plant characteristics and

Journal of Ecology, Volume 110, Issue 6, Page 1442-1454, June 2022., 2022 Our study provides a new perspective into temporal beta diversity of daily riverine diatom communities. The results highlight the importance of taxonomic and functional temporal beta diversity and its decomposition, which is co‐driven by hydrology, nutrient and metal ions. We provide further evidence that environment regimes (e.g.

Functional Ecology, EarlyView.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.

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Cost‐effective and efficient non‐noble‐metal catalysts for selective lignin hydrogenolysis remain elusive, representing a significant challenge in biorefinery. Here, we prepared a nitrogen‐doped carbon supported CoNi bimetallic catalyst, which was successfully derived from zeolitic imidazolate framework (ZIF) via high‐temperature pyrolysis ...

High nitrogen enrichment buffers plant photosynthesis against herbivory damage
Functional Ecology, Volume 40, Issue 1, Page 229-238, January 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivorous insects and nitrogen deposition are key drivers of ecosystem productivity under global change. However, their combined effects on plant photosynthesis, particularly during insect outbreaks, remain poorly understood in natural ecosystems.

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 ...

Shuitu Baochi Xuebao, 2011 采用田间试验结合15 N同位素示踪,研究有机无机肥配施对浙江省杭嘉湖平原稻田氮素利用率及环境效应的影响,结果表明:在施氮量150kg/hm2基础上,加施有机肥3 000kg/hm2,稻谷增产9.8%～17.7%,氮素利用率达到47.9%,比单施化肥提高4.8%。而在施氮量210kg/hm2的基础上增施有机肥,稻谷产量及氮素利用率均呈下降趋势。硝态氮是稻田土壤氮素损失的主要形式,施用有机肥能有效地降低氮素损失率。在施氮量150kg/hm2基础上配施有机肥,氮素通过田间径流的流失率由0.85%降至0.70%,

Shuitu Baochi Xuebao, 2020 为了寻求合理施用肥料与改善水稻养分利用的有效措施，通过2016—2018年在宁夏引黄灌区开展的8组田间试验，研究基于养分专家系统的侧深施肥技术（NE-SD）对水稻产量与养分利用率的影响。结果表明：与农民习惯施肥（FP）处理相比，养分专家系统（NE）处理在减氮24.85%、减磷24.78%、增钾90.71%的基础上，稻谷增产4.71%；氮素、磷素、钾素累积量分别增加2.24%，4.40%，15.09%；氮肥、磷肥、钾肥利用率分别增加9.84，8.78，1.99个百分点；氮肥、磷肥、钾肥农学效率分别增加4 ...

Shuitu Baochi Xuebao, 2011 通过田间试验方法研究了不同控氮比掺混肥(非控、半控和全控)和运筹方式(基施、基施和追施结合)在玉米种植过程中对土壤速效磷、钾养分供应及其利用率的影响。结果表明:控氮比52.5%掺混肥在基施运筹方式下,能够保证玉米各生育阶段尤其是生长发育中后期的土壤磷、钾养分供应,其磷素利用率最高,与其他控氮比掺混肥及运筹方式相比,其磷素利用率提高了2.85%～95.55%。控氮比52.5%掺混肥在基施运筹方式下,与控氮比52.5%掺混肥减量基施处理相比,钾素利用率降低了1.47%,但与其他控氮比掺混肥及运筹方式相比 ...

Shuitu Baochi Xuebao, 2017 在黄淮海地区冬小麦中高产田采用小区试验，以普通尿素基施、普通尿素基施加追施作对比，研究脲醛氮占总氮30%，40%，50%，60%，70%的不同脲醛缓释掺混肥在田间的氮素养分释放特征，以及对土壤氮素养分、小麦产量、氮素利用率及经济效益的影响，探明合理施用脲醛缓释肥最优氮素配比，以达到增加产量、节约资源、增加经济效益的目的。结果表明：脲醛掺混肥氮素释放量在小麦生育进程中呈现高低再高低的变化过程，脲醛氮占总氮40%或50%最有利于土壤氮素供应，脲醛氮所占比例过大或过小，都不利于小麦整个生长期氮素供应 ...
