Green nanocomposites containing biodegradable poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and cellulose nanocrystals/silver (CNC-Ag) nanohybrids were synthesized their properties investigated. It was found that homogeneously dispersed CNC-Ag could act as bifunctional reinforcements to improve the thermal, mechanical antibacterial of PHBV. Compared pristine PHBV, tensile strength maximum decomposition temperature (Tmax) nanocomposite with 10 wt% enhanced by 140% 24.2 °C, respectively....
South China has been experiencing very high rate of acid deposition and severe soil acidification in recent decades, which proposed to exacerbate the regional ecosystem phosphorus (P) limitation. We conducted a 10-year field experiment simulated examine how impacts seasonal changes different P fractions tropical forest with highly acidic soils south China. As expected, addition significantly increased occluded pool but reduced other more labile pools dry season. In wet season, however, did...
Mangrove afforestation is considered an important measure in the “natural-based solution” for mitigating climate warming through sequestering massive carbon (C) into vegetation biomass, yet how planted mangrove species facilitate soil C sequestration remains unclear. Here, we investigated stock, source, and fraction of organic (SOC) over 1 m depth after 20-year five pure plantations (Acrostichum aureum, Acanthus ilicifolius, Aegiceras corniculatum, Kandelia obovate, Excoecaria agallocha) on...
Mangrove afforestation is considered as an important measure in the “natural-based solution” for mitigating climate warming through sequestering massive carbon (C) into vegetation biomass and soil, yet how planted mangrove species will affect soil C sequestration remains unclear. Here, we investigated stock, source, stability of organic (SOC) over 1 m depth after 20-year afforestation, by planting five native (Acrostichum aureum, Acanthus ilicifolius, Aegiceras corniculatum, Kandelia obovate...
<title>Abstract</title> Slow cycling organic matter such as plant lignin components or microbial necromass play important roles in soil carbon (SOC) accumulation, but their relatively importance are rarely quantified have been under debate forest ecosystems. While the traditional hypothesis holds that low-quality litter inputs generally favor more SOC accumulation by selectively storing recalcitrant components, an emerging highlights high-quality effectively promoting formation due to faster...
Abstract Atmospheric acid deposition remains a widespread problem that may influence the protection of carbon (C) in soil by altering organo-mineral interactions. However, impacts additional acidity on interactions and C sequestration naturally acidic tropical soils with high content reactive iron (Fe) phases have not been well studied. Here we sampled nearly 10-yr field experiment gradient treatments (0, 9.6, 32, 96 mol H + ha − 1 yr as nitric sulfuric acid) to examine how acidification...
广州 510650; 2 中国科学院大学, 北京 100049 摘 要 土壤微生物是生态系统重要的组成成分, 尤其是在土壤风化严重, 养分贫瘠的热带和南亚热带森林生态系统中, 微 生物在植物养分的获取、碳循环以及土壤的形成等生态过程中的作用尤为重要。该研究基于鼎湖山南亚热带季风常绿阔叶林 长期(10年)的野外模拟酸沉降实验平台, 探究了土壤微生物群落结构对土壤酸化的响应。结果表明, 酸沉降处理显著降低土 壤pH (即加剧酸化)。土壤酸化对微生物生物量碳(C)含量的影响不大, 但改变了土壤微生物生物量氮(N)和磷(P)的含量, 导致 表层土壤(0-10 cm)微生物生物量C:P和N:P显著提高, 表明土壤酸化可能加剧了微生物P限制。土壤酸化还显著改变了土壤微 生物群落结构, 导致次表层土壤(10-20 cm)真菌:细菌显著增加。进一步分析表明, 土壤pH和土壤有效P含量是影响土壤微生 物群落最为主要的两个因素。
