| 1 | Water regime-nitrogen fertilizer incorporation interaction:Field study on methane and nitrous oxide emissions from a rice agroecosystem in Harbin, China显示文摘Water regime and nitrogen(N) fertilizer are two important factors impacting greenhouse gases(GHG) emission from paddy field, whereas their effects have not been well studied in cold region. In this study, we conducted a two-year field experiment to study the impacts of water regime and N fertilizer on rice yields and GHG emissions in Harbin, China, a cold region located in high latitudes. Our results showed that intermittent irrigation significantly decreased methane(CH_4) emission compared with continuous flooding, however,the decrement was far lower than the global average level. The N_2O emissions were very small when flooded but peaked at the beginning of the disappearance of floodwater. The N fertilizer treatments increased CH_4 emissions at low level(75 kg N/ha). But both CH_4 and N_2O emissions were uninfluenced at the levels of 150 kg N/ha and 225 kg N/ha. Rice yields increased under intermittent irrigation and were highest at the level of 150 kg N/ha. From our results, we recommended that the intermittent irrigation and 150 kg N/ha as the ideal water regime-nitrogen fertilizer incorporation for this area to achieve low GHG emissions without impacting rice yields. | Wenjun Dong Jia Guo Lijun Xu Zhifeng Song Jun Zhang Ao Tang Xijuan Zhang Chunxu Leng Youhong Liu Lianmin Wang Lizhi Wang Yang Yu Zhongliang Yang Yilei Yu Ying Meng Yongcai Lai | 2018 | Journal of Environmental Sciences2018，30，2： | 12 |
| 2 | Allele-defined genome reveals biallelic differentiation during cassava evolution显示文摘Dear Editor,Generation of heterozygous genomes by hybridization between or within species can help maintain plant diversity and serve as a potential source of new species(Baek et al.,2018).Moreover,genomic heterozygosity is associated with genomic coadaptation,developmental stability,and heterosis.Accurate definition of alleles in haplotypes is necessary to precisely characterize allelic variation controlling agriculturally important traits(Shi et al.,2019).Currently,most released genomes have mosaic assembly of haplotypes due to random selection or collapse of alleles during genome assembly(Shi et al.,2019),which masked allelic variation and functional differentiation of divergent alleles in heterozygous species. | Wei Hu Changmian Ji Haitao shi Zhe Liang Zehong Ding Jianqiu Ye Wenjun Ou Gang Zhou Weiwei Tie Yan Yan Jinghao Yang Xiaoying Yang Yunxie Wei Zhiqiang Jin Jianghui Xie Ming Peng Wenquan Wang Anping Guo Biyu Xu Jianchun Guo Songbi Chen Liming Ma Mingcheng Wang Yang Zhou Xiaolong Li Ruoxi Li Siyi Guo Xinhui Xiao Zhongqing Wan Feifei An Jie Zhang Qingyun Leng Yin Li Ray Ming Kaimian Li | 2021 | Molecular Plant2021，14，6： | 8 |
| 3 | Roles of pH in the NH_(4)^(+)-induced corrosion of AZ31 magnesium alloy in chloride environment显示文摘Corrosion behavior of AZ31 magnesium alloy in NH_(4)^(+)-bearing chloride solution with controlled pH was investigated by weight loss experiment, hydrogen collection, and electrochemical test combined with surface morphology and topography observation. The results show that NH_(4)^(+) and pH of the solution can affect the corrosion of AZ31 magnesium alloy. The existence of NH4+affects the formation and dissolution of corrosion products, which makes the protective effect of the corrosion product layer weaker. The change of pH value not only affects the corrosion mechanism of AZ31, but also alters the concentration of NH_(4)^(+) ions in the solution, which further influences the corrosion product layer of AZ31, and finally makes the corrosion of AZ31 change significantly. | Feng Ge Jiaxuan Yin Yue Liu Wenjun Leng Xin Wang Zhongyu Cui | 2022 | Journal of Magnesium and Alloys2022，10，11： | 0 |
| 4 | 畅享自然——让老年人乐享幸福生活的生态社区公园设计显示文摘为了更好地照顾老年人,护理模式正在一步步由家庭护理向社区护理转变。该项目以自然恢复、低影响发展、自我维持的生态社区为设计理念,旨在创造一个健康舒适的户外空间,为老年人提供互动、娱乐和教育服务,加强老年人与家人之间的联系,并完善社区内外的社交网络。项目地址位于安徽省合肥市中心的仙桥社区。该社区占地0.46平方公里,有6个相对独立的居民区。原有社区景观设计陈旧,建筑密度高,仅有一个公共广场和一个袖珍公园,区域内居民很少有接触到绿色和自然的机会。 | Peng Chen Yichen Lou Kun Qian Zhengwei Xing Yunxin Han Wenjun Liu Hongbo Chen Wenqi Chen Xinmiao Zhu Lang Qin Xueying Liu Yu Leng Xinya Hu Suheng Yao | 2023 | 工业设计2023，，9： | 0 |
