The landscaping project mainly includes:garden earthwork balance,garden construction,garden decoration construction,woodwork,steel structure,small landscape architecture,large and small tree planting,shrub planting,flower planting,and greening maintenance project.
(1)Dotted line.Line the line according to the plant spacing of the greening plan.
(2)Digging holes.The width and depth of the pit are determined according to the specifications of the seedlings in the landscaping project.(1)Trees with a DBH of 7 to 10 cm and shrubs with a height of 2 to 2.5 m and evergreen trees with a height of 2.5 to 3 m(including boxwood with a crown diameter of 120 cm or more),the diameter of the tree pit should be 100 cm.The depth should be 70 cm.For seedlings below the above criteria,the pit diameter and depth may be appropriately reduced;for seedlings above the above criteria,the pit diameter and depth should be appropriately increased.(2)3 to 4 years of hedgerow materials,should be wide and deep 30 cm strips or annular grooves,small seedlings should be shallow,large seedlings should be deep.
(3)Change the soil.After planting trees in the construction waste area or on the slopes of earth and rock,after excavating the brick and limestone blocks,the mature soil should be taken from other places to fill the pits.
(4)Digging seedlings.When excavating seedlings,try to protect the root strips,with more roots,deciduous trees with a diameter of gamma,roots of 5 cm or more and no less than 20 cm;evergreen trees with soil balls entangled with grass ropes,so that the roots are not loose.The diameter of the soil ball is not less than 1/4~1/3 of the crown diameter,depending on the shape of the tree.Because the column shape is small,the cone shape should be large.
(5)Miao seedlings.After deciduous trees and shrubs are seedlings,some branches should be cut for transportation;evergreen trees should try to protect the branches and leaves to keep the tree beautiful.Fight for the day,planted on the same day.
(6)Planting.In the landscaping project,the roots of the split and fractured trees should be trimmed before planting the trees,and the cuts should be smooth and flat to facilitate healing.In areas where there are germs,soil or roots should be disinfected,and valuable tree species that are difficult to root can be soaked in root powder solution.Apply the base fertilizer,pick up the debris such as bricks and tiles,plant trees according to the planting point,fill in half of the soil and fill it with the foot.The determinant tree planting requirements are neat and consistent;plexiform planting or curved planting,symmetrical planting,etc.must meet the design requirements.
(7)Irrigation.Immediately after planting,renovate the tree tray or leave the tree pond.Fill the water on the same day and fill it with water.After one week,the soil is wet and re-irrigated to ensure a survival rate of over 95%.
(8)Column.After transplanting the big trees,in order to prevent the tree from tilting after irrigation,it is especially important to plant the evergreen trees and the windy areas with the three pillars in time.
(9)Trimming.In the landscaping project,the shrubs should be thinned after being planted,short-cut and broken,and the branches should be properly retracted to promote the sprouting of new shoots.After the hedgerow is planted,it is necessary to trim the wire to make it tidy and beautiful.Clean the site in time after trimming.
(10)Inspection and acceptance.Before the completion of the landscaping project,the technicians shall check and accept the products,and after reaching the quality requirements,they shall be delivered to the management of the greening unit.
