| 1 | 根际激发效应的发生机制及其生态重要性显示文摘土壤激发效应是指由各种有机物质添加等处理所引起的土壤有机质周转强烈的短期改变。根际是激发效应最主要也是最重要的发生部位。根际激发效应能够反映生态系统土壤碳氮周转的速度,并影响植物、土壤微生物等对养分的获取和竞争,维持生态系统各组分间的养分平衡。虽然对根际激发效应的产生机制已取得一定程度的认知,但是对根际激发效应在土壤碳氮转化过程中的作用机理及其生态重要性依然缺乏足够的理解。该文在论述激发效应的研究历史和主要发生部位的基础上对最新研究进展进行了综合分析,提出了一个具体的根际激发效应的发生机制,深入剖析了影响根际激发效应的生物与非生物因素,并阐释了根际激发效应的生态重要性,对未来根际激发效应的研究方向进行了展望。 | 孙悦 徐兴良 Yakov KUZYAKOV | 2014 | 植物生态学报2014，38，1： | 67 |
| 2 | Responses of Soil Enzyme Activities and Microbial Community Composition to Moisture Regimes in Paddy Soils Under Long-Term Fertilization Practices显示文摘The effects of fertilization on activity and composition of soil microbial community depend on nutrient and water availability;however,the combination of these factors on the response of microorganisms was seldom studied.This study investigated the responses of soil microbial community and enzyme activities to changes in moisture along a gradient of soil fertility formed within a long-term(24 years)field experiment.Soils(0–20 cm)were sampled from the plots under four fertilizer treatments:i)unfertilized control(CK),ii)organic manure(M),iii)nitrogen,phosphorus,and potassium fertilizers(NPK),and iv)NPK plus M(NPK+M).The soils were incubated at three moisture levels:constant submergence,five submerging-draining cycles(S-D cycles),and constant moisture content at 40%water-holding capacity(low moisture).Compared with CK,fertilization increased soil organic carbon(SOC) by 30.1%–36.3%,total N by 27.3%–38.4%,available N by 35.9%–56.4%,available P by 61.4%–440.9%,and total P by 28.6%–102.9%.Soil fertility buffered the negative effects of moisture on enzyme activities and microbial community composition.Enzyme activities decreased in response to submergence and S-D cycles versus low moisture.Compared with low moisture,S-D cycles increased total phospholipid fatty acids(PLFAs)and actinomycete,fungal,and bacterial PLFAs.The increased level of PLFAs in the unfertilized soil after five S-D cycles was greater than that in the fertilized soil.Variations in soil microbial properties responding to moisture separated CK from the long-term fertilization treatments.The coefficients of variation of microbial properties were negatively correlated with SOC,total P,and available N.Soils with higher fertility maintained the original microbial properties more stable in response to changes in moisture compared to low-fertility soil. | LI Weitao WU Meng LIU Ming JIANG Chunyu CHEN Xiaofen Yakov KUZYAKOV Jorg RINKLEBE LI Zhongpei | 2018 | Pedosphere2018，28，2： | 16 |
| 3 | Soil Organic Carbon in a Changing World显示文摘Soil contains more than three times as much carbon (C) as either the atmosphere or terrestrial vegetation.Soil organic C (SOC) is essentially derived from inputs of plant and animal residues,which are processed by the microbiota (bacteria,archaea,protists,fungi and viruses) that dominates SOC transformation and turnover in complex terrestrial environments.A | JIA Zhongjun Yakov KUZYAKOV David MYROLD James TIEDJE | 2017 | Pedosphere2017，27，5： | 7 |
| 4 | New approaches for evaluation of soil health, sensitivity and resistance to degradation显示文摘Assessment of soil health requires complexevaluation of properties and functions responsible for abroad range of ecosystem services. Numerous soil qualityindices (SQI) have been suggested for the evaluation ofspecific groups of soil functions, but comparison of variousSQI is impossible because they are based on a combinationof specific soil properties. To avoid this problem, wesuggest an SQI-area approach based on the comparison ofthe areas on a radar diagram of a combination of chemical,biological and physical properties. The new approach isindependent of the SQI principle and allows rapid andsimple comparison of parameter groups and soils. Anotherapproach analyzing the resistance and sensitivity ofproperties to degradation is suggested for a detailedevaluation of soil health. The resistance and sensitivityof soil properties are determined through comparison withthe decrease of soil organic carbon (SOC) as a universalparameter responsible for many functions. The SQI-areaand resistance/sensitivity approaches were tested based on quences after the ab and on ment of agricultural soils. Both the SQI-area and the resistance/sensitivity approaches areuseful for basic and applied research, and for decisionmakersto evaluate land-use practices and measure thedegree of soil degradation. | Yakov KUZYAKOV Anna GUNINA Kazem ZAMANIAN Jing TIAN Yu LUO Xingliang XU Anna YUDINA Humberto APONTE Hattan ALHARBI Lilit OVSEPYAN Irina KURGANOVA Tida GE Thomas GUILLAUME | 2020 | Frontiers of Agricultural Science and Engineering2020，7，3： | 6 |
| 5 | Soil-plant co-stimulation during forest vegetation restoration in a subtropical area of southern China显示文摘Background: Soil and vegetation have a direct impact on the process and direction of plant community succession, and determine the structure, function, and productivity of ecosystems. However, little is known about the synergistic influence of soil physicochemical properties and vegetation features on vegetation restoration. The aim of this study was to investigate the co-evolution of soil physicochemical properties and vegetation features in the process of vegetation restoration, and to distinguish the primary and secondary relationships between soil and vegetation in their collaborative effects on promoting vegetation restoration in a subtropical area of China.Methods: Soil samples were collected to 40 cm in four distinct plant communities along a restoration gradient from herb(4–5 years), to shrub(11–12 years), to Pinus massoniana coniferous and broadleaved mixed forest(45–46 years), and to evergreen broadleaved forest(old growth forest). Measurements were taken of the soil physicochemical properties and Shannon–Wiener index(SD), diameter at breast height(DBH), height(H), and biomass. Principal component analysis, linear function analysis, and variation partitioning analysis were then performed to prioritize the relative importance of the leading factors affecting vegetation restoration.Results: Soil physicochemical properties and vegetation features showed a significant trend of improvement across the vegetation restoration gradient, reflected mainly in the high response rates of soil organic carbon(SOC)(140.76%), total nitrogen(TN)(222.48%), total phosphorus(TP)(59.54%), alkaline hydrolysis nitrogen(AN)(544.65%),available phosphorus(AP)(53.28%), species diversity(86.3%), biomass(2906.52%), DBH(128.11%), and H(596.97%).The soil properties(pH, SOC, TN, AN, and TP) and vegetation features(biomass, DBH, and H) had a clear coevolutionary relationship over the course of restoration. The synergistic interaction between soil properties and vegetation features had the greatest effect on biomass(55.55%–72.37%), and the soil properties contributed secondarily(3.30%–31.44%). The main impact factors of biomass varied with the restoration periods.Conclusions: In the process of vegetation restoration, soil and vegetation promoted each other. Vegetation restoration was the cumulative result of changes in soil fertility and vegetation features. | Chan Chen Xi Fang Wenhua Xiang Pifeng Lei Shuai Ouyang and Yakov Kuzyakov | 2020 | Forest Ecosystems2020，7，3： | 5 |
| 6 | Straw and biochar strongly affect functional diversity of microbial metabolism in paddy soils显示文摘The application of straw and biochar is widely practiced for the improvement of soil fertility.However,its impact on microbial functional profiles,particularly with regard to paddy soils,is not well understood.The aim of this study was to investigate the diversity of microbial carbon use patterns in paddy soils amended with straw or straw-derived biochar in a 3-year field experiment in fallow soil and at various development stages of a rice crop(i.e.,tillering and blooming).We applied the community level physiological profiling approach,with 15 substrates(sugars,carboxylic and amino acids,and phenolic acid).In general,straw application resulted in the greatest microbial functional diversity owing to the greater number of available C sources than in control or biochar plots.Biochar amendment promoted the use of α-ketoglutaric acid,the mineralization of which was higher than that of any other substrate.Principal component analyses indicated that microbial functional diversity in the biochar-amended soil was separated from those of the straw-amended and control soils.Redundancy analyses revealed that soil organic carbon content was the most important factor regulating the pattern of microbial carbon utilization.Rhizodeposition and nutrient uptake by rice plants modulated microbial functions in paddy soils and stimulated the microbial use of N-rich substances,such as amino acids.Thus,our results demonstrated that the functional diversity of microorganisms in organic amended paddy soils is affected by both physicochemical properties of amendment and plant growth stage. | YUAN Hong-zhao ZHU Zhen-ke WEI Xiao-meng LIU Shou-long PENG Pei-qin Anna Gunina SHEN Jian-lin Yakov Kuzyakov GE Ti-da WU Jin-shui WANG Jiu-rong | 2019 | Journal of Integrative Agriculture2019，18，7： | 4 |
| 7 | Root exudate chemistry affects soil carbon mobilization via microbial community reassembly显示文摘Plant roots are one of the major mediators that allocate carbon captured from the atmosphere to soils as rhizodeposits,including root exudates.Although rhizodeposition regulates both microbial activity and the biogeochemical cycling of nutrients,the effects of particular exudate species on soil carbon fluxes and key rhizosphere microorganisms remain unclear.By combining high-throughput sequencing,q-PCR,and NanoSIMS analyses,we characterized the bacterial community structure,quantified total bacteria depending on root exudate chemistry,and analyzed the consequences on the mobility of mineral-protected carbon.Using well-controlled incubation experiments,we showed that the three most abundant groups of root exudates(amino acids,carboxylic acids,and sugars)have contrasting effects on the release of dissolved organic carbon(DOC)and bioavailable Fe in an Ultisol through the disruption of organo-mineral associations and the alteration of bacterial communities,thus priming organic matter decomposition in the rhizosphere.High resolution(down to 50 nm)NanoSIMS images of mineral particles indicated that iron and silicon colocalized significantly more organic carbon following amino acid inputs than treatments without exudates or with carboxylic acids.The application of sugar strongly reduced microbial diversity without impacting soil carbon mobilization.Carboxylic acids increased the prevalence of Actinobacteria and facilitated carbon mobilization,whereas amino acid addition increased the abundances of Proteobacteria that prevented DOC release.In summary,root exudate functions are defined by their chemical composition that regulates bacterial community composition and,consequently,the biogeochemical cycling of carbon in the rhizosphere. | Tao Wen Guang-Hui Yu Wen-Dan Hong Jun Yuan Guo-Qing Niu Peng-Hao Xie Fu-Sheng Sun Lao-Dong Guo Yakov Kuzyakov Qi-Rong Shen | 2022 | Fundamental Research2022，2，5： | 4 |
