1不同耕作方式对内蒙古旱作农田土壤性状及作物产量的影响显示文摘2005—2008年在内蒙古清水河县进行了定位试验,研究了不同耕作方式下土壤微生物量及土壤营养指标、作物产量的年际变化。结果表明:免耕有利于提高土壤微生物量碳、氮、磷含量,2007和2008年不同耕作方式0~10cm土层土壤微生物量均表现为免耕留高茬覆盖>免耕留低茬覆盖>免耕留高茬>免耕留低茬>传统耕作;免耕有利于提高土壤有机质和土壤养分含量,2007和2008年不同耕作方式0~10cm土层土壤有机质和养分含量均表现为免耕留高茬覆盖>免耕留低茬覆盖>免耕留高茬>免耕留低茬>传统耕作,实施免耕的前3年,玉米产量不稳定,甚至造成玉米减产,第4年免耕增产效应有所显现;不同保护性方式下土壤指标与玉米产量之间的相关度较好,通径分析得知土壤全氮、全磷、速效磷及微生物量碳对玉米产量起直接作用,其中尤以土壤微生物量碳的作用最大;免耕有利于改善内蒙古农田旱作区的土壤生态环境,提高土壤肥力。孙建 刘苗 李立军 刘景辉 KENNETH Dean Sayre 2010生态学杂志2010,29,2:10
2不同耕作方式对内蒙古旱作农田土壤侵蚀的影响显示文摘研究黄河流域内蒙古黄土高原丘陵区农田土壤侵蚀状况,对本区域生态农业建设具有重要的意义。试验于2006年在内蒙古呼和浩特市清水河县进行,设免耕(NT)、免耕覆盖(NS)和传统耕作(CT)3种耕作处理方式,种植作物为胡麻和燕麦,观测了全年降雨量和地表水径流量及土壤流失量。结果表明:免耕覆盖及免耕能显著减少降雨对土壤的侵蚀,与传统耕作相比,免耕覆盖处理的燕麦地地表水径流量和土壤的流失量分别减少21.9%和88.3%;3种耕作方式的土壤侵蚀量均受到坡度的影响,并随着坡度的增大而增大,相同环境条件下,不同作物存在一定差异;通过对3种耕作方式下,胡麻和燕麦田土壤侵蚀量与降雨量的关系符合幂函数,且拟合优度良好,均>0.9。孙建 刘苗 李立军 刘景辉 KENNETH Dean Sayre 2010生态学杂志2010,29,3:7
3不同耕作方式对内蒙古旱作农田土壤微生物量和作物指标的影响显示文摘研究了不同耕作方式下土壤微生物量碳、氮、磷及玉米全生育期叶面积指数、株高和干物质积累量的动态变化,并对土壤指标与作物指标之间的关系进行分析。结果表明:免耕有利于提高土壤微生物量碳、氮、磷含量。不同处理微生物量均表现为:免耕留高茬覆盖>免耕留低茬覆盖>免耕留高茬>免耕留低茬>传统耕翻;土壤微生物量碳、氮、磷含量随土层深度的增加而呈降低趋势。除传统耕翻微生物量碳在10~20cm土层深度含量提高外,其他处理微生物量碳、氮、磷均表现为0~10cm>10~20cm>20~30cm>30~40cm土层深度;土壤生物量碳、氮、磷随季节的变化趋势基本一致,不同处理土壤生物量含量均为7月份含量最高、6月份次之、10月份最低;叶面积指数全生育期呈单峰曲线变化,株高和干物质积累呈S曲线变化。不同处理之间作物指标均表现为免耕留高茬覆盖>免耕留低茬覆盖>免耕留高茬>免耕留低茬>传统耕翻;土壤微生物量与作物指标之间的相关度较高,特别是微生物量磷,土壤微生物量在一定程度上可以反映作物的生长状况。研究结果能够很好地揭示在黄河流域内蒙古农田旱作区实施免耕的优势。孙建 刘苗 李立军 刘景辉 KENNETH Dean Sayre 2009生态学杂志2009,28,11:5
4Anterior ankle arthrodesis显示文摘Ankle arthrodesis is a common procedure that resolves many conditions of the foot and ankle; however, complications following this procedure are often reported and vary depending on the fixation technique. Various techniques have been described in the attempt to achieve ankle arthrodesis and there is much debate as to the efficiency of each one. This study aims to evaluate the efficiency of anterior plating in ankle arthrodesis using customised and Synthes Tomo Fix plates. We present the outcomes of 28 ankle arthrodeses between 2005 and 2012, specifically examining rate of union, patient-reported outcomes scores, and complications. All 28 patients achieved radiographic union at an average of 36 wk; the majority of patients(92.86%) at or before 16 wk, the exceptions being two patients with Charcot joints who were noted to have bony union at a three year review. Patient-reported outcomes scores significantly increased(P < 0.05). Complications included two delayed unions as previously mentioned, infection, and extended postoperative pain. With multiple points for fixation and coaxial screw entry points, the contoured customised plate offers added compression and provides a rigid fixation for arthrodesis stabilization.Gordon L Slater Stephanie C Sayres Martin J O'Malley 2014World Journal of Orthopedics2014,5,1:5
