Grassland establishment and rehabilitation implicates artificial grassland establishing and native pasture rehabilitating. A synthesized technique frame for grassland establishment and rehabilitation in inland salined region should include both biofactors and environmental factors ,i.e. species selection, seedbed preparation, sowing time determination, mixture swards establishment, an effective irrigation and drainage system as well as adequate fertilizing and cutting frequency. The forage yield was 10 t,4.6t and 8.7 t /hm2 respectively for sudangrass(Sorghum sudanense), meadow fescue (Festuca elatior) and mixture of alkaligrass(Puccinellia tenuiflora), sweet clover (Melilotus officinalis) and meadow fescue,2years after the technique implementation at Linze experimental area, Gansu province. The 2 m depth drainage ditch showed an effective function to reduce the total soluble salt content within 060 cm soil profile, meanwhile the soil OM content increased by 0.6 g/kg, available N, total N, total P of soil went up 24.56% ,25.21%,35.07% respectively compared to the initial establishment. N fertilizer significantly increased the total biomass and total density of Leymus dasystachys + Phragmite communis sward in Hexi corridor, the community structure and biomass could be affected by various N fertilizer rate.</em></p><p class='subject'><strong>关 键 词：</strong><a href='/subject/article.aspx?id=6468160' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e6%b2%b3%e8%a5%bf%e8%b5%b0%e5%bb%93%5d' title='河西走廓'>河西走廓</a> <a href='/zk/search.aspx?key=K%3d%5b%e7%9b%90%e6%b8%8d%e5%8c%ba%5d' title='盐渍区'>盐渍区</a> <a href='/subject/article.aspx?id=8887754' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e8%8d%89%e5%9c%b0%e5%bb%ba%e6%a4%8d%5d' title='草地建植'>草地建植</a> <a href='/zk/search.aspx?key=K%3d%5b%e7%bb%bc%e5%90%88%e6%8a%80%e6%9c%af%5d' title='综合技术'>综合技术</a> <a href='/subject/article.aspx?id=8887670' target='_blank'><b class='type_ico_id'></b></a><a href='/zk/search.aspx?key=K%3d%5b%e8%8d%89%e5%9c%b0%e6%94%b9%e8%89%af%5d' title='草地改良'>草地改良</a> </p><p class='class'><strong>分 类 号：</strong><a href='/zk/search.aspx?key=C%3dS812.4' title='S812.4'>S812.4</a>[<a href = '/domain/article.aspx?id=551' >农业科学—草业科学</a>] </p> </div> <div id="content_wzxg" name="wzxg" class="article-graph"> <object width="695" height="250" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" id="FlashID"> <param value="../flash/relation.swf" name="movie"> <param value="high" name="quality"> <param value="opaque" name="wmode"> <param value="6.0.65.0" name="swfversion"> <param value="dataUrl=/ajax/articlerelativegraph.ashx?id=6762441" name="flashVars"> <embed width="695" height="250" src="../flash/relation.swf" type="application/x-shockwave-flash" quality="high" wmode="opaque" flashvars="dataUrl=/ajax/articlerelativegraph.ashx?id=6762441"> </embed> </object> </div> <div class="article-relate-list"> <div class="relate-list"> <p id="ckwx_br"> </p> <h2 name="ckwx" id="ckwx">参考文献：</h2> <div id="listckwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="2jckwx_br"> </p> <h2 name="2jckwx" id="2jckwx">二级参考文献：</h2> <div id="list2jckwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="ohwx_br"> </p> <h2 name="ohwx" id="ohwx">耦合文献：</h2> <div id="listohwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="yzwx_br"> </p> <h2 name="yzwx" id="yzwx">引证文献：</h2> <div id="listyzwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="2jyzwx_br"> </p> <h2 name="2jyzwx" id="2jyzwx">二级引证文献：</h2> <div id="list2jyzwx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="tbywx_br"> </p> <h2 name="tbywx" id="tbywx">同被引文献：</h2> <div id="listtbywx"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> <div class="relate-list"> <p id="xgqklw_br"> </p> <h2 name="xgqklw" id="xgqklw">相关期刊文献：</h2> <div id="listxgqklw"> <p class='submit'> <img src='/images/loading.gif' width='16' height='16' /> 正在载入数据... </p> </div> </div> </div> </div> <div class="article-about"> <div class="about-box"> <h5 class="name">相关的主题<tt><a class="hide" href="#"></a></tt></h5> <div class="about-list"> </div> </div> <div class="about-box"> <h5 class="name">相关的作者对象<tt><a class="" href="#"></a></tt></h5> <div class="about-list" style="display: none;"> </div> </div> <div class="about-box"> <h5 class="name">相关的机构对象<tt><a class="" href="#"></a></tt></h5> <div class="about-list" style="display: none;"> </div> </div> </div> </div> </div> <script type="text/javascript" src="/scripts/articlerelation.min.js"></script> <script type="text/javascript" src="/scripts/articlerightrelation.min.js"></script> <script type="text/javascript" src="/scripts/articledown.min.js"></script> <div class="layer-box download" id="downloadlayer" style="display: none"> <div class="close"> <a onclick="closedown()" href="javascript:void(0)"> <img src="/images/layer-close.png" width="21" height="21" alt="" /> </a> </div> <h5 class="layer-title">下载全文</h5> <div id="downloadinfo"></div> </div> <div class="layer-box download" id="downloadlayer2" style="display:none;min-height:100px;width:500px;"> <p> <img src="/images/loading2.gif" width="64" height="64"> <span style="font-size:20px;vertical-align:middle;padding-bottom:50px;">正在链接到云南高校图书馆文献保障联盟下载...</span> </p> </div> <script id="bdshare_js" data="type=tools&uid=0" type="text/javascript"></script> <script type="text/javascript"> $(function () { var rd = GetQueryString("rd");
