| 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 |

| 12 | Conventional tillage improves the storage of soil organic carbon in heavy fractions in the Loess Plateau, China显示文摘Soil labile organic carbon(C) plays an important role in improving soil quality. The relatively stable fractions of soil organic C(SOC) represent the bulk of SOC, and are also the primary determinant of the long-term C balance of terrestrial ecosystems. Different land use types can influence the distribution patterns of different SOC fractions. However, the underlying mechanisms are not well understood. In the present study, different fractions of SOC were determined in two land use types: a grazed grassland(established on previously cultivated cropland 25 years ago, GG) and a long-term cultivated millet cropland(MC). The results showed that C concentration and C storage of light fractions(LF) and heavy fractions(HF) presented different patterns along the soil profiles in the two sites. More plant residues in GG resulted in 91.9% higher LF storage at the 0–10 cm soil depth, further contributed to 21.9% higher SOC storage at this soil depth; SOC storage at 20–60 cm soil depth in MC was 98.8% higher than that in GG, which could be mainly attributed to the HF storage 104.5% higher than in GG. This might be caused by the long-term application of organic manure, as well as the protection from plough pan and silt- and clay-sized particles. The study indicated that different soil management practices in this region can greatly influence the variations of different SOC fractions, while the conventional tillage can greatly improve the storage of SOC by increasing heavy fractions. | HAN Huige LI Xudong NIU Decao Sharon J HALL GUO Ding WAN Changgui Jennifer K LEARNED FU Hua | 2015 | Journal of Arid Land2015，7，5： | 1 |
