| 1 | 秸秆还田对土壤微生物影响的研究进展显示文摘秸秆还田是有效利用秸秆资源的重要途径。土壤微生物在秸秆腐解和营养元素释放过程中具有举足轻重的作用,而另一方面秸秆本身也会对土壤微生物产生较大的影响。秸秆还田概况入手,从不同的秸秆还田方式、外源添加物、不同的秸秆还田量、耕作制度和转基因秸秆几个方面综述了目前国内外秸秆还田对土壤微生物影响的研究报告。目前已有文献的研究大多集中在土壤微生物量方面,但并没有形成一致的观点,且缺乏对土壤微生物长期动态和功能群的研究。据此认为应在今后的研究中加强以下几个方面:以更为先进的方法结合多种研究手段揭示秸秆还田过程中土壤微生物的实际情况;开展关于秸秆分解整个过程中土壤微生物的动态变化研究;以微生物功能群为单位研究秸秆还田对微生物的影响;采用多种不同的方法和长期的观察以研究转基因作物秸秆还田后对土壤微生物生态的影响。 | 伍玉鹏 彭其安 Muhammad Shaaban 郝蓉 胡荣桂 | 2014 | 中国农学通报2014，30，29： | 34 |
| 2 | 氮肥配施下不同C/N作物残渣还田对红壤温室气体排放的影响显示文摘氮肥配施能够促进还田秸秆的分解,为了解其对不同C/N秸秆还田下温室气体排放的影响,采用培养实验方法,研究了油菜饼(C/N为4)、玉米秸秆(C/N为28)、水稻秸秆(C/N为41)和小麦秸秆(C/N为71)等4种不同C/N植物残渣在不同量氮肥(无氮、低氮和高氮)配施下对红壤温室气体(CO2、CH4和N2O)排放的影响。结果显示,氮肥配施增加了不同植物残渣的CO2-C累积排放量,且仅在高C/N的小麦秸秆处理中发现存在显著性差异,在低氮和高氮下CO2-C累积排放量分别达到1 271.44、1 212.83 mg·kg-1,显著高于无氮肥配施的883.40 mg·kg-1。土壤N2O累积排放量最大的为油菜饼处理组,低氮量的配施进一步增强了N2O的产生,其累积排放量达到5 550.42μg·kg-1,显著高于无氮肥配施的4 430.44μg·kg-1,然而当氮肥施用量进一步增加时却抑制了N2O的排放(3752.84μg·kg-1)。氮肥配施并未显著影响玉米秸秆和小麦秸秆处理组的N2O累积排放量。在培养期内,每一个处理均表现为CH4的吸收现象,氮肥施用能够增加土壤对CH4的累积吸收量,但差异显著性仅在对照和油菜饼处理中发现。 | 伍玉鹏 刘田 彭其安 Muhammad Shaaban 胡荣桂 | 2014 | 农业环境科学学报2014，33，10： | 17 |
| 3 | 生物质炭对茶园土壤改良及茶叶品质的影响显示文摘近年来,茶树种植过程中化肥的超量施用造成茶园土壤酸化加剧和有机质含量降低等一系列问题,进而影响到茶叶的产量和品质。生物质炭一般呈碱性,具有含碳量高、比表面积大、高度生物化学稳定性和较强的吸附性能等特性,能够增加土壤碳储量,提高土壤pH值和养分有效性,对于茶园土壤固碳、土壤改良和抑制土壤氮磷流失、改善农产品品质等方面有较大作用。针对我国茶园土壤存在的主要问题,以生物质炭的特性及生物质炭改良土壤的作用机理为研究对象,重点阐述了生物质炭在茶园酸化土壤改良、土壤氮素淋失阻控、土壤固碳增汇等方面的效应,以及生物质炭提高茶叶产量和提升茶叶品质方面的作用机理。基于以上研究,展望了生物质炭在茶园管理方面的理论研究方向,为生物质炭在农业生产中的应用和推广提供科学依据。 | 孙贇 Muhammad Shaaban 何志龙 张水清 林杉 | 2017 | 中国土壤与肥料2017，，6： | 11 |
| 4 | 外加碳氮对不同有机碳土壤N_2O和CO_2排放的影响显示文摘以两种有机碳含量不同的土壤为对象,采用室内培养试验方法,研究了外加可溶性碳氮对黄棕壤(高有机碳含量)和紫色土(低有机碳含量)N_2O、CO_2排放的影响。试验设置五种处理分别为:对照(CK),低氮(LN),高氮(HN),低氮配施碳(LNC)和高氮配施碳(HNC)。结果表明,土壤有机碳含量较高的黄棕壤各处理N_2O与CO_2排放均高于紫色土。与对照相比,单施氮肥显著促进了两种土壤N_2O排放,紫色土HN处理N_2O排放最高,而黄棕壤LN处理最高;与单施氮肥相比,LNC和HNC处理均显著降低了紫色土N_2O排放,而黄棕壤仅LNC处理N_2O排放显著降低。外源碳的输入显著提高了两种土壤CO_2排放,但单施氮肥对CO_2排放影响不明显。黄棕壤N_2O排放通量与CO_2排放通量呈极显著正相关,而紫色土N_2O排放通量与CO_2排放通量没有相关关系。上述结果说明,外加可溶性碳氮源对土壤呼吸及硝化-反硝化强度有一定的激发效应。 | 田亚男 张水清 林杉 Muhammad Shaaban 何志龙 | 2015 | 农业环境科学学报2015，34，12： | 8 |

| 8 | Assessing soil nitrous oxide emission as affected by phosphorus and nitrogen addition under two moisture levels显示文摘Agricultural soils are deficient of phosphorus(P) worldwide. Phosphatic fertilizers are therefore applied to agricultural soils to improve the fertility and to increase the crop yield. However, the effect of phosphorus application on soil N_2O emissions has rarely been studied. Therefore, we conducted a laboratory study to investigate the effects P addition on soil N_2O emissions from P deficient alluvial soil under two levels of nitrogen(N) fertilizer and soil moisture. Treatments were arranged as follows: P(0 and 20 mg P kg^(–1)) was applied to soil under two moisture levels of 60 and 90% water filled pore space(WFPS). Each P and moisture treatment was further treated with two levels of N fertilizer(0 and 200 mg N kg^(–1) as urea). Soil variables including mineral nitrogen(NH_4^+-N and NO_3~–-N), available P, dissolved organic carbon(DOC), and soil N_2O emissions were measured throughout the study period of 50 days. Results showed that addition of P increased N_2O emissions either under 60% WFPS or 90% WFPS conditions. Higher N_2O emissions were observed under 90% WFPS when compared to 60% WFPS. Application of N fertilizer also enhanced N_2O emissions and the highest emissions were 141 μg N_2O kg^(–1) h^(–1) in P+N treatment under 90% WFPS. The results of the present study suggest that P application markedly increases soil N_2O emissions under both low and high soil moisture levels, and either with or without N fertilizer application. | Bashir Ullah Muhammad Shaaban HU Rong-gui ZHAO Jin-song LIN Shan | 2016 | Journal of Integrative Agriculture2016，15，12： | 2 |
| 9 | Appraisal of MsepCSP14 for chemosensory functions in Mythimna separata显示文摘Chemosensory proteins (CSPs) have great contributions in performing diverse functions in insects. However, physiological appraisal of chemosensory protein genes still remains elusive in insects. We studied expression patterns and binding affinities of MsepCSP14, a chemosensory protein, in Mythimna separata. The distinct functions of MsepCSP14 were validated by employing different molecular techniques. The MsepCSP14 had high resemblance of sequence with chemosensory proteins of other insect family members. The MsepCSP14 expression was higher in antennal tissues of females than other tissues. Fluorescence binding assay validated that binding of nine out of 21 ligands to MsepCSP14 was higher at pH 7.4 than at pH 5.0. Three dimensional modeling (3D) and docking analysis predicted that amino acid residues of MsepCSP14 were involved in binding of compounds, and behavior assay displayed that adults of M. separata considerably responded to four volatiles from compounds demonstrating strong binding ability to MsepCSP14. Results of the present study suggest that MsepCSP14 is likely to mediate chemosensory functions in M. separata. | Aneela Younas Muhammad Irfan Waris Muhammad Shaaban Muhammad Tahir ul Qamar Man-Qun Wang | 2022 | Insect Science2022，29，1： | 1 |
| 10 | The effect of dolomite amendment on soil organic carbon mineralization is determined by the dolomite size显示文摘Background:The size of lime material is vital for the efficiency of ameliorating soil acidity,thereby influencing soil biochemical processes.However,the effects of different sized lime material application on soil organic carbon(SOC)mineralization are yet to be elucidated.Therefore,a 35-day incubation experiment was conducted to determine the effects of three particle size fractions(0.5 to 0.25,0.25 to 0.15,and<0.15 mm)of dolomite on SOC mineralization of two acidic paddy soils.Results:CO_(2) emission was increased by 3–7%,11–21%,and 32–49%for coarse-,medium-,and fine-sized dolomite treatments,respectively,compared to the control in both soils.They also well conformed to a first-order model in all treatments,and the estimated decomposition rate constant was significantly higher in the fine-sized treatment than that of other treatments(P<0.05),indicating that SOC turnover rate was dependent on the dolomite size.The finer particle sizes were characterized with higher efficiencies of modifying soil pH,consequently resulting in higher dissolved organic carbon contents and microbial biomass carbon,eventually leading to higher CO_(2) emissions.Conclusions:The results demonstrate that the size of dolomite is a key factor in regulating SOC mineralization in acidic paddy soils when dolomite is applied to manipulate soil pH. | Hongtao Wu Jinli Hu Muhammad Shaaban Peng Xu Jinsong Zhao Ronggui Hu | 2021 | Ecological Processes2021，10，1： | 1 |
| 11 | Influence of Plant Growth Promoting Rhizobacterial Inoculation on Wheat Productivity Under Soil Salinity Stress显示文摘Soil salinity affects the growth and yield of crops.The stress of soil salinity on plants can be mitigated by inoculation of plant growth promoting bacteria(PGPR).The influence of PGPR inoculation on wheat(Triticum aestivum L.)crop productivity under salinity stress has not been properly addressed so far.Therefore,the present study was conducted to investigate the effects of various PGPR strains(W14,W10 and 6K;alone and combined)at several growth attributes of wheat plant under different soil salinity gradients(3,6 and 9 dS m-1).The growth attributes of wheat(height,roots,shoots,spikes,grains quality,biological and economical yield,nutrients nitrogen,phosphorus and potassium in grains)were highly affected by salinity and decreased with increasing salinity level.The PGPR inoculation substantially promoted growth attributes of wheat and prominent results were observed in W14×W10×6K treatment at all salinity levels.The results suggest that inoculation of PGPR is a potential strategy to mitigate salinity stress for improving wheat growth and yield. | Muhammad Zafar-ul-Hye Tariq Shahzad Bhutta Muhammad Shaaban Shahid Hussain Muhammad Farooq Qayyum Umar Aslam Zahir Ahmad Zahir | 2019 | Phyton-International Journal of Experimental Botany2019，88，2： | 1 |
| 12 | 生物质炭调控药用植物连作障碍的研究进展显示文摘我国是中药材种植大国,但不合理的栽培方式和管理措施导致中药材连作障碍在种植区普遍存在,造成药材减产变质、道地产区转移、资源保护与利用不协调等,严重影响药用植物生长发育。因此对中药材连作土壤进行修复是解决中药材连作障碍的一个关键措施。生物质炭一般呈碱性,是一种良好的土壤改良剂,能够增加土壤养分、改良酸化土壤、提升植物品质,近年来得到广泛关注与应用,因此利用生物质炭作为调理剂来缓解中药材连作障碍具有一定潜力。本文针对我国中药材连作障碍的可能成因及潜在危害,分析生物质炭在解决药用植物连作造成的土壤理化性质改变、土壤微生物区系改变、化感自毒危害等问题上的作用,并对生物质炭在药用植物生产上的应用潜力进行展望。 | 高华 涂昊泽 赵钰湲 孔雯 夏文建 王飞儿 Muhammad Shaaban 林杉 | 2024 | 福建农业学报2024，39，1： | 0 |
