Organize relevant personnel to be familiar with and learn the technical data of the project, such as drawings, construction specifications, atlas and technical documents. , and arrange a special person to jointly review the drawings and communicate with the design unit. At the same time, set up a construction site survey team to prepare for the construction site plane setting and floor elevation network survey records.

Second, the geological and topographic arrangements

Clean up all rubbish, weeds and sundries on the construction site.

In strict accordance with the design standards and landscape requirements, the site shall be leveled, the earthwork shall be backfilled and leveled to the design elevation, and the site shall be excavated. The thickness of soil layer planted with turf is not less than 30cm, the flower bed is not less than 40cm, and the trees are not less than 70cm. Arrange the broken topsoil into a plane or curved surface that meets the requirements, and adjust the overall slope according to the design requirements of the drawings.

Third, fixed-point pay-off

According to the design drawings, the pattern will be arranged to the construction site in proportion, and then plant the plant materials according to its requirements. In the construction, the planting of plants can be divided into two forms: regular and natural. Regular lofting is relatively simple, that is, regular and fixed-point setting-out is carried out according to the design drawings to achieve a neat and unified effect.

If the actual situation is inconsistent with the drawings, appropriate adjustments should be made after obtaining the consent of the supervisor.

Fourth, dig planting holes and apply base fertilizer.

After the planting position is determined, the specifications of digging holes can be determined according to the root system and soil conditions of trees. Tree planting holes are mainly circular, and flowers are arranged in rows. The planting hole is about 30 cm larger than the diameter of the root ball. The application of base fertilizer should be carried out according to the operation procedures.

Verb (abbreviation for verb) Selection, transportation and planting of seedlings

When selecting seedlings, the error between the seedling size and the design specification shall not exceed 5%, and the seedlings shall be selected according to the design specification. Trees should have lush branches and leaves, straight trunks and symmetrical crown parts. In addition, it should be noted that more care should be taken when transporting saplings, so as not to drag the saplings. You should be light, light, light, and don't hurt the clay ball. If the seedlings are transported far away, they should be covered with wet grass or covered with plastic film for protection.

Finally, according to the requirements of the work instruction for seedling planting, the trees are fixed with protective piles. The order of seedling planting is big tree, medium and small tree, shrub, ground cover and lawn. No matter what the weather is like, all kinds of seedlings should be watered with fixed root water and sprayed with branches and leaves to keep moisture.
