Construction of Landscape Greening

Landscape greening mainly includes: balanced layout of garden earthwork, construction of garden civil engineering, construction of garden decoration, woodworking, steel structure, small garden buildings, tree planting, shrub planting, flower planting, and greening maintenance.

1. Draw a line at a fixed point. Draw a line according to the spacing between plants and rows in the landscaping plan.

2. Dig a pit. The width and depth of the pit are determined based on the specifications of the green engineering seedlings. Trees with a diameter of 7-10 centimeters at breast height, shrubs with a height of 2-2.5 meters, and evergreen trees with a height of 2.5-3 meters (including boxwood balls with a crown diameter of over 120 centimeters). Its diameter should be 100 centimeters and its depth should be 70 centimeters. For seedlings below the above standards, the pit diameter and depth should be appropriately reduced; For seedlings above the above standards, the pit diameter and depth should be appropriately increased. Hedge materials that have been around for 3-4 years should be excavated in a wide, 30cm deep strip or ring ditch. Small seedlings should be shallow, while large seedlings should be deep.

3. Replace the soil. Planting trees in the construction of garbage dumps or soil and rock slopes, excavating bricks and stones, and taking mature soil from other places for filling.

4. Dig seedlings. When excavating seedlings, the root system should be protected as much as possible, and fibrous roots should be used more often. The diameter of deciduous trees should be chicken green, and the distance above the root system should not be less than 20cm; Evergreen trees should use grass ropes to wrap the soil ball, so that the root system of the soil ball is not loose, and the diameter of the soil ball is not less than 1/4 to 1/3 of the crown diameter, depending on the shape of the tree.

Transportation of seedlings. After deciduous trees and shrubs sprout, some branches should be cut off for transportation; Evergreen trees should protect their branches and leaves as much as possible and maintain their beautiful appearance. Strive to ship on the same day, at the same factory.

5. Planting. Before planting trees in landscaping, it is necessary to trim the root system of concrete that has been split or broken reasonably. The cutting edge should be smooth and the surface should be flat to facilitate healing. Areas with pathogens should be analyzed for soil or root environment disinfection. Rare economic tree species that are difficult to root can be soaked in root powder solution. Apply base fertilizer, pick out debris such as bricks, stones, and tiles, plant trees according to the planting points, fill half of the soil with a foot pedal, and then fill again. The problem of planting trees in rows requires students to be neat and consistent; Cluster planting, curved planting, and symmetrical planting should meet the development requirements of teaching design.

6. Irrigation. Immediately repair the tree tray or leave the tree pond after planting, and irrigate during the day. After one week, the soil will dry and wet again, ensuring a survival rate of over 95%.

7. Pillar. After transplanting, it is very important to timely use three brackets to plant evergreen trees and windy areas in order to prevent the tree from tilting after irrigation.

8. Pruning. In landscaping projects, dry branches should be thinned, broken, and scratched after planting, and perennial branches should be shortened to promote the germination of new branches. After planting, the fence should be trimmed with lines to make it neat and beautiful. After pruning, the construction site should be cleaned up in a timely manner.

9. Inspection and acceptance. Before the completion of landscaping construction, technical personnel shall conduct acceptance inspection. After meeting the quality requirements, it will be handed over to the greening unit for management.
