园林绿化工程主要包含:园林土石方平衡整理，园林土建施工，园林装饰施工，木作，钢构，小型景观建筑，大小乔木栽植，灌木栽植，花卉栽植，以及绿化养护工程。
The landscape engineering mainly includes: landscape earthwork balance, landscape civil construction, landscape decoration construction, wood work, steel structure, small landscape architecture, tree planting, shrub planting, flower planting, and green maintenance engineering.
(一)定点划线。按照绿化规划图的株行距划线。
（1） Dot dash. Line out according to the spacing of plants and lines in the greening plan.
(二)挖坑。根据园林绿化工程中苗木规格确定坑的宽度与深度。(1)胸径7~10厘米的乔木和高度2~2.5米的灌木及高度2.5~3米的常绿树(包括冠径120厘米以上的黄杨球等)，其树坑直径应达100厘米，深度应达70厘米。低于上述标准的苗木，可适当减小坑径与深度;高于上述标准的苗木，应适当加大坑径与深度。(2)3~4年的绿篱材料，应挖宽、深各30厘米的条形沟或环状沟，小苗宜浅，大苗应深。
（2） Dig a hole. Determine the width and depth of the pit according to the specifications of seedlings in the landscaping project. (1) Trees with a DBH of 7-10 cm, shrubs with a height of 2-2.5 m and evergreen trees with a height of 2.5-3 m (including boxwood balls with a crown diameter of more than 120 cm) should have a pit diameter of 100 cm and a depth of 70 cm. For seedlings lower than the above standard, the pit diameter and depth can be appropriately reduced; for seedlings higher than the above standard, the pit diameter and depth should be appropriately increased. (2) For hedgerow materials of 3-4 years, a strip or ring ditch with width of 30cm and depth of 30cm respectively shall be dug. The small seedling shall be shallow and the large seedling shall be deep.
(三)换土。在建筑垃圾地段或土石山坡植树，挖出砖灰石块后，应从别处取熟化土填坑。
（3） Replace the soil. Trees shall be planted in the construction waste section or earth rock slope. After the bricks, ashes and stones are excavated, the mellow soil shall be taken from other places to fill the pit.
(四)掘苗。挖掘苗木时要尽量保护根条，多带须根，落叶乔木直径伽晴、5厘米以上的根不短于20厘米;常绿树要带土球缠草绳，做到根部土球不松不散，土球直径不小于冠径的1/4~1/3，依树形而定，因柱形叮小，圆锥形应大。
（4） Digging seedlings. When excavating seedlings, try to protect the root strips with fibrous roots. The diameter of deciduous trees is Jiaqing, and the roots with a diameter of more than 5cm are not less than 20cm. The evergreen trees should wrap the soil balls around the grass ropes with soil balls to make sure that the soil balls at the roots are not loose, and the diameter of the soil balls is not less than 1 / 4 ~ 1 / 3 of the crown diameter. It depends on the tree shape. Because the column shape is small, the cone shape should be large.
(五)运苗。落叶乔、灌木起苗后，应剪去部分枝条，以便运输;常绿树木要尽量保护枝叶，以保持树形美观。争取当天起运，当天栽植。
（5） Transport seedlings. After the seedlings of deciduous trees and shrubs are raised, some branches shall be cut for transportation; the evergreen trees shall try to protect the branches and leaves to keep the beautiful tree shape. Strive to start transportation and plant on the same day.
(六)栽植。园林绿化工程中栽树前要对劈裂、折伤的根系进行修剪，要求剪口光滑平整，以利愈合。有病菌的地方要进行土壤或根部消毒，难生根的名贵树种可浸生根粉溶液。施基肥，拣出砖石瓦块等杂物，按定植点栽树，填一半土用脚踏实后再填。行列式植树要求整齐一致;丛状式栽植或弧形栽植、对称栽植等要符合设计要求。
（6） Planting. Before planting trees in landscaping project, the root system of split and broken trees shall be pruned, and the cut shall be smooth and flat to facilitate healing. Where there are pathogens, soil or root disinfection should be carried out. Precious tree species that are difficult to root can be soaked with rooting powder solution. Apply base fertilizer, pick out bricks, stones, tiles and other sundries, plant trees according to the planting site, fill half of the soil, and then fill it with foot rest. The row planting shall be neat and consistent; the cluster planting, arc planting and symmetrical planting shall meet the design requirements.
