| 1 | 施氮量对夏玉米根际和非根际土壤酶活性及氮含量的影响显示文摘在华北平原潮土上进行田间试验,研究施氮量对夏玉米根际和非根际土壤酶活性及氮含量的影响.结果表明:不同施氮水平下土壤酶活性均表现出一致的季节性变化趋势.与不施氮处理相比,施氮处理能显著提高根际和非根际土壤硝态氮含量及根际土壤铵态氮含量,显著增强土壤几丁质酶、β-葡萄糖苷酶、纤维素酶和木聚糖酶活性.在整个玉米生育期内,非根际土壤硝态氮含量显著高于根际土壤;非根际土壤铵态氮含量在灌浆期显著高于根际土壤,但在苗期和完熟期则显著低于根际土壤;根际土壤几丁质酶、β-葡萄糖苷酶、纤维素酶和木聚糖酶活性都显著高于非根际土壤.施氮对土壤有机质含量没有显著影响;在0~180 kg·hm^(-2)施氮范围内,施氮可明显增加土壤全氮含量,但当施氮量超过180 kg·hm^(-2)时,土壤全氮含量则明显下降.综上,适量施氮能显著增强土壤酶活性,提高土壤全氮含量,改善土壤生化性质. | 梁国鹏 Houssou A.Albert 吴会军 武雪萍 蔡典雄 高丽丽 李景 王碧胜 李生平 | 2016 | 应用生态学报2016，27，6： | 34 |
| 2 | 桑树枝和肉桂枝生物炭吸附及钝化土壤镉效果比较显示文摘【目的】探讨桑树枝和肉桂枝生物炭对水和土壤环境中镉(Cd)污染的修复效果,为实现木质农林废弃物的资源化利用和Cd污染环境修复提供理论依据。【方法】将桑树枝和肉桂枝置于400℃慢速热裂解2 h制备生物炭,采用等温吸附试验研究其吸附Cd特征,通过盆栽试验检验其钝化土壤Cd以及阻止小白菜吸收富集Cd的作用效果。【结果】桑树枝生物炭(MB400)和肉桂枝生物炭(CB400)对Cd的吸附均可用Langmuir等温吸附模型进行拟合,最大吸附容量(Q0)分别达到4 305.61、442.77 mg/kg,MB400吸附Cd的能力较强,这可能与其pH值、灰分(Ash)、阳离子交换量(CEC)和有效磷(AP)含量较高有关。添加MB400可显著降低土壤中有效态镉(AvCd)含量,但CB400处理没有显著效果。添加3%的两种生物炭,小白菜生物量明显提高,Cd的生物富集因子(BCF值)从对照的5.95分别降至4.29(MB400)和4.85(CB400)。【结论】两种生物炭对Cd具有较强的吸附能力,能够钝化土壤Cd,阻止小白菜吸收富集,且桑树枝生物炭的效果更好。 | 黄玉芬 杜毅 王钰静 周丽萍 Houssou Assa Albert 黄连喜 魏岚 刘忠珍 | 2022 | 广东农业科学2022，49，3： | 2 |
| 3 | Valuation of Rice Postharvest Losses in Sub-Saharan Africa and Its Mitigation Strategies显示文摘Data on rice harvest and postharvest loss in Sub-Sahara Africa(SSA)is scanty making it difficult for stakeholders to appreciate the loss and set priority areas for loss reduction along the value chain.To address this problem,a protocol was developed and validated for postharvest loss(PHL)quantification in SSA.Quantitative losses at each segment were determined by field measurements.Interactive effect of origin of rice(domestic versus imported)and type of processing(white versus parboiled milled)on rice price in 33 markets in Africa was used to estimate qualitative loss for both white and parboiled milled rice.Total PHL for rice in SSA in 2018 is estimated at about US$10.24 billion,representing 47.63%of the expected total production.The highest loss recorded was quantitative loss before and during harvesting,followed by qualitative loss along the entire value chain,quantitative loss during milling,parboiling,threshing in that order,with the lowest being quantitative loss during drying.Priority areas to be targeted for PHL reduction in SSA and some loss mitigation tools and technologies piloted or suitable for SSA are proposed. | Sali Atanga NDINDENG Alphonse CANDIA Delphine Lamare MAPIEMFU Vohangisoa RAKOTOMALALA Nahemiah DANBABA Kurahisha KULWA Paul HOUSSOU Sow MOHAMMED Ousman M.JARJU Salimata S.COULIBALY Elvis A.BAIDOO Jean MOREIRA Koichi FUTAKUCHI | 2021 | Rice science2021，28，3： | 1 |

| 11 | Characterization of biochars from woody agricultural wastes and sorption behavior comparison of cadmium and atrazine显示文摘Woody agricultural wastes have created enormous pressure on the environment.In this study,mulberry and cinnamon woodchips were reclaimed and prepared for biochars through pyrolysis technique at four different temperatures.Physicochemical properties showed that mulberry biochar exhibited higher pH,CEC and ash content than cinnamon biochar at each temperature.All biochars were utilized as adsorbents to remove cadmium(Cd)and atrazine(AT)from water.The adsorption isotherms were found to be well fitted by Freundlich and Langmuir models.The maximum adsorption capacities were 5306.41 mg/kg for Cd adsorption and 538.89 mg/kg for AT adsorption,respectively.Moreover,the principal component analysis,XPS and FTIR analysis proved that precipitation with phosphate in biochars acted as the key property that governed the adsorption capacity of Cd,whereas the porosity demonstrated a significant impact on the adsorption capacity of AT.Partial least squares(PLS)model was considered to be more favorable for predicting AT adsorption than Cd adsorption.The results of the present paper will be helpful for selecting most effective biochars from locally available woody agricultural byproducts that are optimized for contaminants removal from environment. | Xiang Li Yufen Huang Xiaoliang Liang Lianxi Huang Lan Wei Xiaodong Zheng Houssou Assa Albert Qing Huang Zhongzhen Liu Zhaojun Li | 2022 | Biochar2022，4，1： | 0 |
| 12 | Biochar and soil properties limit the phytoavailability of lead and cadmium by Brassica chinensis L.in contaminated soils显示文摘The current study investigated the effect of biochars derived from cinnamomum woodchip,garden waste and mulberry woodchip on soil phytoavailable lead(Pb),cadmium(Cd)pools,and their uptake by Chinese cabbage(Brassica chinensis L.).The biochars were produced at 450℃of pyrolysis temperature.The contaminated soils were collected from Yunfu(clas-sified as Udept),Jiyuan(Ustalf)and Shaoguan(Udult)cities in China at the depth of 0-20 cm and amended with biochars at the rate of 3%w/w.After mixing the soil with biochar for 14 days,the Chinese cabbage was planted in the amended soils.Then,it was harvested on the 48th day after sowing period.In Udult soil,Chinese cabbage died 18 days after sowing period in control and soils amended with cinnamomum and mulberry biochars.Although only plants grown with the garden waste biochar treatment survived in Udult soil,amendment of garden waste or mulberry biochars at 3%w/w(450℃)to Udult soil significantly increased(4.95-6.25)soil pH compared to other biochar treatments.In Udept and Ustalf soils,the application of garden waste and mulberry biochars significantly improved plant biomass compared to control,albeit it was dependent on both biochar and soil properties.Garden waste biochar significantly decreased soil Cd phytoavailable concentration by 26%in the Udult soil,while a decrease of soil Cd phytoavailable concentration by 16%and 9%was observed in Ustalf and Udept soils,respectively.The available phosphorus in biochar and soil pH were important factors controlling toxic metal phytouptake by the plant.Thus,the amendment of soil with biochar at 3%can effectively reduce the mobility of Cd and Pb in soil and plant uptake.However,biochar and soil properties should be well-known before being used for soil toxic metal immobilization. | Assa Albert Houssou Paramsothy Jeyakumar Nabeel Khan Niazi Lukas Van Zwieten Xiang Li Lianxi Huang Lan Wei Xiaodong Zheng Qing Huang Yufen Huang Xianzhi Huang Hailong Wang Zhongzhen Liu Zhenrui Huang | 2022 | Biochar2022，4，1： | 0 |
