及规格划分Ⅰ级、Ⅱ级、Ⅲ级。4.1.3 行道树树干端直，树形端正，分枝点高度

2.8

m～

m。4.1.4 以树型匀称优美，树冠规整，枝叶茂密，主枝分布均匀，枝干健壮为形态指标。4.1.5松柏类及木棉、小叶榄仁等枝条轮生类植物无截顶。4.1.6

～

相关规定执行。4.2 灌木类4.2.1

苗木为容器苗。4.2.2

质量分级划分Ⅰ级、Ⅱ级。4.2.3

灌木球以枝干密实，冠形丰满为形态指标。4.2.4

自然型丛生灌木以冠形自然丰满，分枝均匀，生长健壮为形态指标。4.2.5

自然型单干灌木以主干明显直立，分枝均匀、冠形饱满、生长健壮为形态指标。4.2.6

以株高、冠幅、地径、一级分枝数、密实度作为分级指标，按表

～B.2

相关规定执行。4.3 棕榈类4.3.1苗木宜为假植苗。4.3.2 质量分级划分Ⅰ级、Ⅱ级。4.3.3 单干型棕榈以树形匀称优美、比例协调，尾径无明显缩小，叶片色泽正常，顶芽完好为形态指标。4.3.4 丛生型棕榈以杆数多且匀称，树形比例协调，生长健壮，叶片色泽正常作为形态指标4.3.5

C.1～C.2相关规定执行。DB4501/T

0014—20235 检测方法5.1 形态指标采用目测法检测。5.2 分级指标5.2.1 测量工具及精度 测量胸径、地径、腹径、尾径、单杆地径等直径时用胸径尺、卡尺、游标卡尺，读数精确到0.1

cm。

1。 一级分枝数、分枝级数、叶片数、杆数采用目测法检测。5.2.2 测量 当苗木主干断面变形时，胸径或腹径的测量应取最大值和最小值的平均值作为测定值。 当苗木基部膨胀或变形时，地径的测量应在其基部近上方正常处进行测定。 冠幅的测量应取树冠最宽面的最大值和最窄面的最小值的平均值作为测定值。最大值与最小值的比值应小于

1.5。密实度的测量以灌木球密实度样板（见附录

D）进行比对确定。6 检验规则6.1 检验条件

6.1.1 苗木检验地点宜在施工现场进行。6.1.2 供需双方同时履行检验手续，供方应向需方提供苗木名称、类型、规格、苗龄、移植次数等历史档案记录。6.2 组批同一车次运输进场的苗木为同一批次，应进行一次性检验。6.3 等级划定苗木同时满足所有分级指标划定为对应等级；当分级指标不在同一等级时，以最低指标划分等级。6.4 抽样按批次检验的应采用随机抽样方式，每批次株以下的全数检验，100株以下的抽检不少于10100株及以上的抽检比例为10％。造型树、孤植树、对植树及其他设计要求的重要景观树应逐株检验，其他苗木应按批次进行抽样。6.5 检验判定6.5.1 同一批次抽样苗木对应等级的分级指标合格率不低于

95不到相应等级。6.5.2 当检验工作有误或其他方面不符合有关规定需进行复检时，以复检结果为准。cmcmcm
