1土壤保水剂对土壤持水特性及作物出苗的影响显示文摘保水剂农业节水、保水、增产新技术一直是国内外学者重点研究的对象之一,但目前缺少一些基础性研究数据,本文着重就保水剂物理保水特性及对作物出苗的影响进行探讨。结果表明保水剂具有良好的膨胀性、吸水快和减少蒸发的特性,特别是改变水分特征曲线,大幅度增加土壤有效水,促进作物出苗作用尤为突出,可成为未来人工调控土壤水分的重要手段,应用前景非常广阔。蔡典雄 王小彬 Keith Saxton 1999土壤肥料1999,,1:67
2Sperm DNA fragmentation, recurrent implantation failure and recurrent miscarriage显示文摘证据正在增加精子 DNA 的正直可能也与培植失败和周期性的流产(RM ) 有关。调查这,在有在 vitro 授精,与 RM 诊断的 16 个女人和七位最近的父亲(控制) 列在后面的周期性的培植失败(RIF ) 的 35 个女人的搭挡的精子 DNA 破碎被检验。精子由测试和终端 deoxynucleotidyl transferase dUTP 刻痕结束标记的精子染色质分散(SCD )(TUNEL ) 是检验密度前和密度以后的 centrifugation 试金。在在三之间的搭挡或精子集中,活动性或形态学组织的任何一个的年龄没有重要差别。而且,在 DNA 破碎由也测量了的精子没有明显的差别测试。不管多么虽然平均在所有的精子 DNA 破碎组织当由 SCD 测试测量了时,在准备精子是统计上更低的,这没从 TUNEL 试金与结果被看见。这些结果不支持精子 DNA 破碎是 RIF 或 RM 的一个重要原因的假设,否则测试的那精子 DNA 正直在如此的病人有价值。它也在从精子 DNA 破碎测试解释数据加亮测试方法论和精子准备方法之间的重要差别。Carol Coughlan Helen Clarke Rachel Cutting Jane Saxton Sarah Waite William Ledger Tinchiu Li Allan A Pacey 2015Asian Journal of Andrology2015,17,4:17
3WINTER RUNOFF AND EROSION ON NORTHWESTERN USA CROPLAND显示文摘Crop management is an important factor in preventing winter runoff and erosion on non-irrigatedcropland of the Northwestern Wheat and Range Region of the U.S. Much of the total annual runoff andsoil loss from agricultural land in the region occurs as a result of rain and snowmelt on frozen and thawingsoil. Quantifying these effects is important for hydrologic model development and calibration, and fordesigning and selecting crop managements to prevent erosion. An experimental setup with several runoffplots under a number of crop management systems was installed at the Palouse Conservation Field Stationin the fall of 1978. Data were collected from natural events on the replicated plots for l3 years. Frost,thaw, and snow depths were measured on the plots regularly. Runoff and sediment samples were obtainedfrom collection tanks on a daily or event basis. Data were analyzed and events were separaed into frozensoil, thawing soil, and non-frozen soil. Crop management had a substantial effect on infiltration and runoff,but an even more significant impact on soil erosion.D.K.
