| 1 | CO_2 mitigation potential in farmland of China by altering current organic matter amendment pattern显示文摘The estimation of the global warming mitigation potential in terrestrial ecosystems is of great importance for decision makers to adopt measures to increase soil organic carbon (SOC) as well as to reduce greenhouse gas (GHGs) emissions. In this paper, we compiled data published in peer-reviewed journals, and conducted a holistic analysis of the effects of organic matter amendment on soil organic carbon sequestration, methane (CH4) and nitrous oxide (N2O) emissions in paddy and upland systems. Results showed that organic matter amendment increased soil organic carbon content, and apparent conversion rate of organic matter carbon to soil organic carbon in paddies was constant, while that in uplands decreased along with amendment years at 25 years time scale. Organic matter amendment during the rice season led to large CH4-C emissions, e.g on average 99.5 g CH4-C per kg organic carbon input under intermittent flood conditions, and 191.7 g CH4-C per kg organic carbon input under continuous flood conditions, respectively. By alteration of organic matter amendment from rice season to off-rice upland crop season, estimated CH4-C emissions in China could be cut by 3.5 Tg yr-1, accounting for 63% of current CH4-C emissions (5.5 Tg). If organic matter amendment percentage was increased from current 30% to future 50% of organic matter production and by alteration of organic matter amendment from rice season to off-rice upland crop season, the equivalent CO2-C mitigation potential in farmland of China would be 49.2 Tg yr-1 at the 10th year organic matter amendment and 36.0 Tg yr-1 at the 30th year amendment. These findings are important not only for China but also for the other rice production countries to increase farmland global warming mitigation. | CADISCH Georg | 2010 | Science China Earth Sciences2010，53，9： | 12 |
| 2 | Paddy System with a Hybrid Rice Enhances Cyanobacteria Nostoc and Increases N2 Fixation显示文摘Biological nitrogen (N) fixation (BNF) plays a significant role in maintaining soil fertility in paddy field ecosystems. Rice variety influences BNF, but how different rice varieties regulate BNF and associated diazotroph communities has not been quantified. Airtight, field-based 15N2-labelling grow th chamber experiments were used to assess the BNF capac 辻 y of different rice varie ties. In addition, both the 16S rRNA and nifH genes were sequenced to assess the influence of different rice varieties on bacterial and diazotrophic communities in paddy soils. After subjecting a rice-soil system to 74 d of continuous airtight, field-based 15N2 labelling in pots in a growth chamber, the amounts of fixed N were 22.3 and 38.9 kg ha^-1 in inbred japonica (W23) and hybrid indica (IIY) rice cultivars plan ted in the rice-soil systems, respectively, and only 1%—2.5% of the fixed N was allocated to the rice plants and weeds. A greater abundance of diazotrophs was found in the surface soil (0-1 cm) under IIY than under W23. Sequencing of the 16S rRNA gene showed significantly greater abundances of the cyanobacterial genera Nostoc, Anabaena, and Cylindrospermum under IIY than under W23. Sequencing of the nifH gene also showed a significantly greater abundance of Nostoc under IIY than under W23. These results indicate that the hybrid rice cultivar (IIY) promoted BNF to a greater extent than the inbred rice cultivar (W23) and that the increase in BNF might have been due to the enhanced heterocystous cyanobacteria Nostoc. | MA Jing BEI Qicheng WANG Xiaojie LIU Gang Georg CADISCH LIN Xingwu ZHU Jianguo SUN Xiaoli XIE Zubin | 2019 | Pedosphere2019，29，3： | 7 |
| 3 | 全球尺度过量氮元素输入的土壤功能响应显示文摘很少证据显示南半球大陆高度风化、低磷、酸性土壤中氮(N)循环与北美和欧洲有很大的差别。来自南半球的证据表明:不同的土地利用方式中,氮损失的形态和时间模式有相似性;不同大陆林地地表/枯枝落叶层的碳氮比(C:N)对于全球尺度上一系列过程有强烈的预示性;根据北半球增施氮对'受磷制约'的生态系统影响的归纳很可能不适用于南半球生态系统,当地植物结构上和生理上对低磷土壤的适应使得磷制约概念变得可疑;大大地增加了氮的输入和周转的土地利用变化很可能是南半球生态系统的最大威胁;局部氮施入的增加很可能与北半球观测到的效果相似。 | Mark Adams Phil Ineson Dan Binkley Georg Cadisch Naoko Tokuchi Mary Scholes Kevin Hicks 孙会首(译) | 2004 | AMBIO-人类环境杂志2004，33，B12： | 2 |
