1长期保护性耕种方式对农田表层土壤性质的影响显示文摘研究了不同耕种方式对澳大利亚同一地区3种土壤表层(0-5cm)理化性质的作用,以揭示保护性耕作对土壤质量恢复的影响。结果表明:免耕穴播/保留残茬(DD/SR)、多年生人工草地(PP)和自然草地(NP)表层土壤的〉2mm水稳性团聚体含量、全氮、有机碳含量、田间持水量均显著高于其相应对照传统耕作/秸秆焚烧(CC/SB)、人工草地/作物轮作(PPC)和耕作(CT)的;土壤全氮含量、田间持水量分别与有机碳含量之间有极显著的正相关关系(r=0.994**,r=0.996**,n=6),而受土壤质地等因素的影响较小;在同一类型的土壤上,土壤有机碳含量与水稳定性团聚体含量之间存在显著的相关性;在不同试验区,耕作措施对表层土壤容重和孑L隙分布的影响存在较大差异;秸秆焚烧和施用石膏对表层土壤的pH及交换性阳离子含量有较大的影响。研究表明长期保护性耕作、草田轮作或多年生草地有利于提高表层土壤有机碳含量和结构稳定性,从而改善土壤的供肥供水能力。张国盛 K Y Chan G D Li D P Heenan 2008生态学报2008,28,6:45
2膳食中钠(盐)与血压的关系及其他膳食因素可能的调节作用显示文摘现有资料表明,膳食钠(盐)与血压直接相关。以往大多数研究结果来自缺乏膳食数据的研究;因此,这种钠-血压关系是否受其他膳食因素调节尚不清楚。国际宏量/微量营养素和血压研究(international study on macro/micronutrients and blood pressure,INTERMAP)结果显示,在控制多种非膳食因素情况下,年龄40~59岁的男性和女性4680人(中国、日本、英国和美国的17个人口样本)的血压与24h尿钠排泄和尿钠/钾直接相关。刘莉 叶鹏 Stamler J Chan Q Daviglus ML Dyer AR Van Horn L Garside DB Miura K Wu Y Ueshima H Zhao L Elliott P INTERMAP Research Group 2018中华高血压杂志2018,26,4:8
