一、大苗ink href="https://mip.huaniaoy.com/yangzhifangfa/2308/" title="移植养护大全" rel="CaiLiaoClicked" class="orange-bottom mip-element mip-layout-container" style="margin: 0px; padding: 0px; color: rgb(20, 124, 202); outline: none medium; display: inline; position: relative;">移植ink>、栽植是关键

1.挖好移植穴、灌足底水。移植穴的大小要根据云杉苗木的大小确定，一般苗高6米以上，穴深大于1.5米，直径不小于1.8米;苗高5～6米，穴深大于1.3米，直径不小于1.5米;苗高4～5米，穴深大于1.1米，直径不小于1.3米;苗高3-4米，穴深大于1.0米，直径不小于1.1米;苗高2～3米，穴深大于1.0米，直径不小于1.0米;苗高1～2米，穴深大于0.6米，直径不小于0.8米。移植穴挖好后在苗木移植前灌一次底水，ink href="https://mip.huaniaoy.com/yangzhifangfa/2205/" title="水量养护大全" rel="CaiLiaoClicked" class="orange-bottom mip-element mip-layout-container" style="margin: 0px; padding: 0px; color: rgb(20, 124, 202); outline: none medium; display: inline; position: relative;">水量ink>为穴深一半。

2.备好栽植土。拣尽栽植土内的石块、草根、建筑垃圾、废ink href="https://mip.huaniaoy.com/yangzhifangfa/2005/" title="塑料袋养护大全" rel="CaiLiaoClicked" class="orange-bottom mip-element mip-layout-container" style="margin: 0px; padding: 0px; color: rgb(20, 124, 202); outline: none medium; display: inline; position: relative;">塑料袋ink>等杂物。有条件的还可以掺些农家肥，便于苗木栽植后ink href="https://mip.huaniaoy.com/yangzhifangfa/2234/" title="生根养护大全" rel="CaiLiaoClicked" class="orange-bottom mip-element mip-layout-container" style="margin: 0px; padding: 0px; color: rgb(20, 124, 202); outline: none medium; display: inline; position: relative;">生根ink>和吸收养分。

3.栽实扶正苗木、灌足定苗水。大苗栽植时先在穴内填埋30厘米厚的栽植土，再根据冠形一次摆好苗木位置，尽量减少苗木在穴内的移动次数，尤其是4米以上的大苗，以免受土球和树冠的重量而损伤根系。苗木摆好后再填埋1/3的移植土，用木棍在穴和土球之间捣实，然后将土穴填满后用脚踩实。修好蓄水土坑用小水慢灌，灌足定苗水，一周后再灌一次定根水，这一次定根水对成活率影响较大，比较关键。

4.搭上保护架、固定苗木。由于ink href="https://mip.huaniaoy.com/yangzhifangfa/2269/" title="春季养护大全" rel="CaiLiaoClicked" class="orange-bottom mip-element mip-layout-container" style="margin: 0px; padding: 0px; color: rgb(20, 124, 202); outline: none medium; display: inline; position: relative;">春季ink>风大，树木ink href="https://mip.huaniaoy.com/yangzhifangfa/2294/" title="浇水养护大全" rel="CaiLiaoClicked" class="orange-bottom mip-element mip-layout-container" style="margin: 0px; padding: 0px; color: rgb(20, 124, 202); outline: none medium; display: inline; position: relative;">浇水ink>后土壤较松软，固持力较低，容易被风吹斜、吹倒，或者随风摇摆，致使根系ink href="https://mip.huaniaoy.com/yangzhifangfa/2196/" title="生长养护大全" rel="CaiLiaoClicked" class="orange-bottom mip-element mip-layout-container" style="margin: 0px; padding: 0px; color: rgb(20, 124, 202); outline: none medium; display: inline; position: relative;">生长ink>受损，影响ink href="https://mip.huaniaoy.com/yangzhifangfa/2114/" title="成活养护大全" rel="CaiLiaoClicked" class="orange-bottom mip-element mip-layout-container" style="margin: 0px; padding: 0px; color: rgb(20, 124, 202); outline: none medium; display: inline; position: relative;">成活ink>。
