Integrative Conservation, Volume 4, Issue 4, Page 686-694, December 2025.The soil fungicide reduces the occurrence of pathogenic fungi in invaded soil and at the same time promotes the recruitment of mycorrhizal fungi and saprophytic fungi by the plants. The addition of biochar to the invaded soil has a negative legacy effect on subsequent invasive plants, while it exerts a positive enhancement effect on native plants ...

Zhejiang Daxue xuebao. Lixue ban, 2014 以猪粪和鸡粪为原料，研究了热解温度（200~700 ℃）对生物质炭物理和化学性质的影响.结果表明，生物质炭的得率随着热解温度的升高逐渐降低，猪粪生物质炭的得率较鸡粪高；猪粪和鸡粪生物质炭的灰分含量分别为41. 2%~70. 6%和20. 3%~48.1%.生物质炭均为中性或碱性，300~700 ℃热解所制备的生物质炭的pH值不仅与灰分含量有关，还可能与Ca含量密切相关.红外光谱表明，低温热解条件下(≤300 ℃)生物质炭中的含氧官能团与原材料相比无明显变化；但是当热解温度高于400 ℃时 ...

Joint Extraction Method for Spatial Relations in Chinese Geological Texts
Earth and Space Science, Volume 12, Issue 8, August 2025.Abstract Extracting spatial relations of geological entities is an important prerequisite for achieving natural language processing tasks such as geological knowledge question answering and semantic search, and is an important means to achieve structural reconstruction of unstructured geological data.

Gongye shui chuli, 2023 针对水体中存在的抗生素污染现象，以小粒咖啡果壳为原料，采用限氧裂解法在500 ℃下制备了生物炭MCS-1，随后分别用KOH和H2SO4改性MCS-1，制得改性生物炭MCS-2和MCS-3，研究了3种生物炭对磺胺噻唑（ST）的吸附特性和吸附机理。实验结果表明：3种生物炭均具有多层级孔隙结构，与未改性生物炭MCS-1相比，MCS-2和MCS-3具有更发达的孔道结构和比表面积。3种生物炭对ST的吸附均符合准二级动力学模型和Freundlich模型，表明吸附过程主要为物理化学作用，且吸附速率主要受薄膜扩散控制 ...

Systematic Entomology, Volume 50, Issue 3, Page 495-518, July 2025.Using genomic data from 285 species across 19 planthopper families, we conducted the first phylogenomic study targeting global planthoppers and inferred their phylogeny with the highest resolution so far. We proposed taxonomic changes including the establishment of a new family Borysthenidae stat. rev. and a new superfamily Meenoploidea superfam.

Shuitu Baochi Xuebao, 2022 为实现秸秆资源化利用和强化生物质炭基肥生产应用,以洞庭湖芦荻秸秆热解生物质炭为基质,采用包膜和混合造粒技术,以改性淀粉为黏合剂,辅以膨润土、腐殖酸等材料制备包膜炭基肥(CT)和混合炭基肥(MT)。以生物质炭占比10%(T1),15%(T2),20%(T3),25%(T4)和30%(T5),从微观形态结构、养分释放速率、粒径及抗压强度等基本性质进行择优筛选,将筛选后的炭基肥处理(CT2、CT3、CT4和MT1、MT2、MT3)与普通复合肥(NPK)、不施肥(CK)共8个处理进行室内水稻盆栽试验 ...

An assessment of future rewilding potential in the United Kingdom
Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Restoring ecosystems is an imperative for addressing biodiversity loss and climate change, and achieving the targets of the Kunming–Montreal Global Biodiversity Framework. One form of restoration, rewilding, may have particular promise but may also be precluded by requirements for other forms of land use now or in the future.

Global status, impacts, and management of rocky temperate mesophotic ecosystems
Conservation Biology, Volume 38, Issue 1, February 2024.Abstract The ecology and function of rocky temperate mesophotic ecosystems (TMEs) remain poorly understood globally despite their widespread distribution. They typically occur at 20–150 m (the limit of photosynthesis), and on rocky substratum they support rich benthic communities and mobile fauna.

Gongye shui chuli, 2017 用KMnO4改性玉米芯生物炭，并用改性生物炭吸附水中的Cu2+和氨氮。结果表明：改性后，生物炭中的-OH基团数量增多且其表面有新生态MnO2生成，吸附能力增强；生物炭吸附Cu2+、氨氮的最佳pH为7；共存Na+不影响生物炭对Cu2+的吸附，但显著影响对氨氮的吸附。生物炭对Cu2+、氨氮的吸附分别遵循准二级、一级动力学模型。Freundlich模型能更好地模拟生物炭对Cu2+的吸附行为，Langmuir模型能更好地模拟生物炭对氨氮的吸附行为。

GCB Bioenergy, Volume 16, Issue 1, January 2024.The use of biochar increased greenhouse gas (GHG) emissions but countered the harm caused by GHG emissions by considerable soil carbon sequestration resulting in a negative carbon footprint. Furthermore, the use of biochar lowered the proportion of CH4 and N2O, demonstrating that biochar usage has a considerable positive effect on GHG emissions ...
