| 1 | Soil physical quality as influenced by long-term fertilizer management under an intensive cropping system显示文摘In China’s major rice(Oryza sativa L.)production regions,the traditional fertilization modes are challenged by the continued decrease in manure and increase in mineral fertilizer.However,limited information exists on the influences of long-term fertilizer management on soil organic carbon(SOC)and soil physical properties under the intensive rice production system in southern China.The objective of this study was to characterize the changes of soil physical properties as related to mineral fertilizer,crop residues,and manure application based on a long-term field experiment.The experiment,initiated in 1986,has five treatments:unfertilized,mineral fertilizer alone,rice residues plus mineral fertilizer,low manure rate plus mineral fertilizer,and high manure rate plus mineral fertilizer.The cropping system consists of barley(Hordaum vulgare L.),early rice,and late rice,three crops in a year.In May 2006,after barley harvest,soil samples were collected from the 0~10 cm and 10~20 cm layers to determine SOC concentration,aggregate size distribution,bulk density(rb),saturated hydraulic conductivity(Ks),and soil water characteristic curves(SWCC).The results indicated that manure significantly reducedrb,increased SOC concentration,soil aggregation,Ks,transmission and storage porosity,as well as water retention capacity.Combined application of crop residue and mineral fertilizer also improved soil physical properties,but the improvement by mineral fertilizer alone was limited.Correlation analysis demonstrated that S,the slope of the SWCC at its inflection point,was closely associated with the selected physical parameters,suggesting S was an effective parameter for soil physical quality evaluation.Nevertheless,in applying the S-theory,a unified approach to define the residual water content should be considered. | Du Zhangliu Liu Shufu Xiao Xiaoping Yang Guangli Ren Tusheng | 2009 | International Journal of Agricultural and Biological Engineering2009，2，1： | 4 |

| 5 | The applications of single-atom alloys in electrocatalysis:Progress and challenges显示文摘The development of cost-effective and highly efficient electrocatalysts to accelerate distinct electrochemical reactions is essential to help the industry to achieve a low-carbon footprint.Single-atom alloys(SAAs)with the characteristics of unique electronic structures,well-defined active sites,and maximum atom utilization demonstrate promising potential to replace traditional noble metal catalysts.SAAs are expected to tailor the adsorption properties of reaction species,thus promoting electrocatalytic behaviors.Herein,representative synthetic strategies including wet chemistry,galvanic replacement,dealloying,and atomic layer deposition are introduced,followed by a summary of applications of SAAs in hydrogen evolution reaction,oxygen evolution reaction,oxygen reduction reaction,carbon dioxide reduction reaction,and ethanol electro-oxidation to provide an in-depth understanding of the structure–activity relationship.Moreover,the challenges and perspectives in this emerging field of SAAs are discussed. | Yumin Da Rui Jiang Zhangliu Tian Xiaopeng Han Wei Chen Wenbin Hu | 2023 | SmartMat2023，4，1： | 1 |

| 8 | Afforestation with an age-sequence of Mongolian pine plantation promotes soil microbial residue accumulation in the Horqin Sandy Land, China显示文摘Land use change affects the balance of organic carbon(C)reserves and the global C cycle.Microbial residues are essential constituents of stable soil organic C(SOC).However,it remains unclear how microbial residue changes over time following afforestation.In this study,16-,23-,52-,and 62-year-old Mongolian pine stands and 16-year-old cropland were studied in the Horqin Sandy Land,China.We analyzed changes in SOC,amino sugar content,and microbial parameters to assess how microbial communities influence soil C transformation and preservation.The results showed that SOC storage increased with stand age in the early stage of afforestation but remained unchanged at about 1.27-1.29 kg/m2 after 52 a.Moreover,there were consistent increases in amino sugars and microbial residues with increasing stand age.As stand age increased from 16 to 62 a,soil pH decreased from 6.84 to 5.71,and the concentration of total amino sugars increased from 178.53 to 509.99 mg/kg.A significant negative correlation between soil pH and the concentration of specific and total amino sugars was observed,indicating that the effects of soil acidification promote amino sugar stabilization during afforestation.In contrast to the Mongolian pine plantation of the same age,the cropland accumulated more SOC and microbial residues because of fertilizer application.Across Mongolian pine plantation with different ages,there was no significant change in calculated contribution of bacterial or fungal residues to SOC,suggesting that fungi were consistently the dominant contributors to SOC with increasing time.Our results indicate that afforestation in the Horqin Sandy Land promotes efficient microbial growth and residue accumulation in SOC stocks and has a consistent positive impact on SOC persistence. | GUO Jingwen SONG Xueshu WANG Xiao DU Zhangliu LU Sen | 2024 | Journal of Arid Land2024，16，4： | 0 |
