2.2定点放样

测量人员进行定点的放样，严格按照一公顷面积植树440棵放样（即植树间

距4.77米），测量后做明显标记。

2.3挖种植穴：

种植穴直径60cm,深度为60cm，要求坑壁光滑，上下面口径基本一致。

2.4树苗检查

树干挺直，没有明显弯曲，无蛀干害虫和未愈合的机械损伤；

树冠丰满，枝条分布均匀、无严重病虫危害，树叶正常；

根系发育良好、无严重病虫危害；

土球大小为苗木胸径的10倍以上。

2.5植树

2.5.1种植的质量标准：

种植的苗木品种为景观树柚树，苗木的本身与地面垂直，没有倾斜；

严格按照测量定点种植，横平竖直，树木应在一条直线上；

树苗高度为1.5米左右，相邻两株高差不超过30cm;

种植深浅与原土痕持平；

保持树苗土球完好，包装物

应取出。

2.5.2种植的程序和方法:

树木入穴后，土球放稳，树干直立，拆除并取出包装物；

种植后在树木四周筑成高5-10cm的灌水土堰，方便浇水；

种植后需要支撑的树木，用树枝或者竹竿支撑牢固，使树木保持直立；

新植树木24小时内浇第一遍水，三日内浇第二遍水，十日内浇上第三遍水，三遍水后转入后期养护；

每次浇水后均整堰、堵漏、培土、扶直树干，第三遍水后封堰。

2.6养护：

新植树苗完成后进行养护，主要项目包括：

浇水、、防治病虫、补栽未成活树苗、直至交付验收。
