| 1 | 牧草如何生长——植物生长与放牧管理之关联(英文)显示文摘适当管理饲料饲草资源的基本原则是理解多年生牧草如何生长。长期以来 ,对根系生长有了基本的了解 ,对去叶和环境对根系生长的影响也知之甚多。然而 ,对去叶、干旱及其他环境因素对多年生牧草的影响以及这些牧草对去叶的反应缺乏应有的理解。从牧草返青到开花 ,植物处于短枝阶段 ,适度放牧并不对多年生牧草的健康和活力造成危害 ,因为植物会弥补其失去的叶片。然而 ,当牧草从短枝向长枝阶段 (节间伸长和开花期 )转移时 ,碳水化合物主要用于节间伸长和开花过程。在开花后和休眠前期 ,碳水化合物主要向茎基和植物基部转移 ,以供来年新枝条的发育。因此 ,在花后和休眠前期 ,放牧系统必须被调节到“无放牧”状态。“无放牧”状态 ,如休息、轮牧、延迟轮牧和快速轮牧制 ,其价值在于这种定期的禁牧可提高多年生牧草的活力 ,改善草地的健康状况 ,并且在不利的环境条件下 。 | Ronald E Sosebee David B Wester J Carlos Villalobos Carlton M Britton Changgui Wan Hisham Nofal | 2005 | 草业学报2005，14，1： | 8 |

| 3 | Groundwater contributions in water-salt balances of the lakes in the Badain Jaran Desert,China显示文摘Groundwater-fed lakes are essential for the ecology in arid and semiarid regions.As a typical arid region,the Badain Jaran Desert (BJD) is famous in the world for the presence of a large number of groundwater-fed saline lakes among the mega dunes.Based on the up to date geological surveys and observations,this study analyzed the groundwater contributions in water-salt balances of the lakes in the desert.We found different types of springs,including the sublacustrine springs that indicate an upward flow of groundwater under the lakebed.A simplified water balance model was developed to analyze the seasonal variations of water level in the Sumu Barun Jaran Lake,which revealed an approximately steady groundwater discharge in the lake and explained why the amplitude of seasonal changes in lake level is less than 0.5 m.In addition,a salt balance model was developed to evaluate the salt accumulations in the groundwater-fed lakes.The relative salt accumulation time is 800–7,000 years in typical saline lakes,which were estimated from the concentration of Cl-,indicating a long history evolution for the lakes in the BJD.Further researches are recommended to provide comprehensive investigations on the interactions between the lakes and groundwater in the BJD. | GONG Yanping WANG Xusheng HU B Xiao ZHOU Yangxiao HAO Chunbo WAN Li | 2016 | Journal of Arid Land2016，8，5： | 7 |
| 4 | Effect of nitrogen fertilization on yield, N content, and nitrogen fixation of alfalfa and smooth bromegrass grown alone or in mixture in greenhouse pots显示文摘Planting grass and legume mixtures on improved grasslands has the potential advantage of realizing both higher yields and lower environmental pollution by optimizing the balance between applied N fertilizer and the natural process of legume biological nitrogen fixation. However, the optimal level of N fertilization for grass-legume mixtures, to obtain the highest yield, quality, and contribution of N2 fixation, varies with species. A greenhouse pot experiment was conducted to study the temporal dynamics of N2 fixation of alfalfa(Medicago sativa L.) grown alone and in mixture with smooth bromegrass(Bromus inermis Leyss.) in response to the addition of fertilizer N. Three levels of N(0, 75, and 150 kg ha–1) were examined using 15N-labeled urea to evaluate N2 fixation via the 15 N isotope dilution method. Treatments were designated N0(0.001 g per pot), N75(1.07 g per pot) and N150(2.14 g per pot). Alfalfa grown alone did not benefit from the addition of fertilizer N; dry matter was not significantly increased. In contrast, dry weight and N content of smooth bromegrass grown alone was increased significantly by N application. When grown as a mixture, smooth bromegrass biomass was increased significantly by N application, resulted in a decrease in alfalfa biomass. In addition, individual alfalfa plant dry weight(shoots+roots) was significantly lower in the mixture than when grown alone at all N levels. Smooth bromegrass shoot and root dry weight were significantly higher when grown with alfalfa than when grown alone, regardless of N application level. When grown alone, alfalfa's N2 fixation was reduced with N fertilization(R2=0.9376, P=0.0057). When grown in a mixture with smooth bromegrass, with 75 kg ha–1 of N fertilizer, the percentage of atmospheric N2 fixation contribution to total N in alfalfa(%Ndfa) had a maximum of 84.07 and 83.05% in the 2nd and 3rd harvests, respectively. Total 3-harvest %Ndfa was higher when alfalfa was grown in a mixture than when grown alone(shoots: |t|=3.39, P=0.0096; root: |t|=3.57, P=0.0073). We believe this was due to smooth bromegrass being better able to absorb available soil N(due to its fibrous root system), resulting inlower soil N availability and allowing alfalfa to develop an effective N2 fixing symbiosis prior to the 1st harvest. Once soil N levels were depleted, alfalfa was able to fix N2, resulting in the majority of its tissue N being derived from biological nitrogen fixation(BNF) in the 2nd and 3rd harvests. When grown in a mixture, with added N, alfalfa established an effective symbiosis earlier than when grown alone; in monoculture BNF did not contribute a significant portion of plant N in the N75 and N150 treatments, whereas in the mixture, BNF contributed 17.90 and 16.28% for these treatments respectively. Alfalfa has a higher BNF efficiency when grown in a mixture, initiating BNF earlier, and having higher N2 fixation due to less inhibition by soil-available N. For the greatest N-use-efficiency and sustainable production, grass-legume mixtures are recommended for improving grasslands, using a moderate amount of N fertilizer(75 kg N ha–1) to provide optimum benefits. | XIE Kai-yun LI Xiang-lin HE Feng ZHANG Ying-jun WAN Li-qiang David B Hannaway WANG Dong QIN Yan Gamal M A Fadul | 2015 | Journal of Integrative Agriculture2015，14，9： | 5 |
