1 to do the preparatory work before construction
1.1 Design Details and drawings organize joint trial work. Green construction is different from the construction works, as long as you can in strict accordance with construction drawings, green construction is another creative process, there is how to fully embody the concept of design ideas and problems, therefore, drawing tests, is extremely important, requiring detailed design intent and design units, construction units should deeply understand the overall project design to flexibility in the construction, such as: When planting trees, which Zhu straight, which Zhu oblique, oblique angle, how to make Gazing in its position with the harmonious and lively fun, and that is reflected from the construction drawings do not come out.

1.2 The construction organization design. Garden project since, including a number of individual projects, often in the construction of the garden project involved the coordination and cooperation, therefore, in the construction process to achieve a unified leadership, the department, to coordinate the projects consistent, so that construction can proceed smoothly, it is often said that the construction design. According to the actual characteristics of landscape engineering, landscape engineering construction design should include the following aspects: �� in obtaining construction project, shall be design requirements for good project budget for the project started to do construction site, construction materials, construction machinery, construction teams and other aspects of preparation. �� According to the requirements of the construction period, organizational materials, construction equipment, construction workers into the construction site, plan good progress, guarantee continuous construction. construction organizations and construction organizations who need a clear set of projects completed in several projects, as well as their respective relations and the engineering team responsible, careful not to ignore the conservation group. arranged according to construction schedule Plan, in chronological order of arrangement.

2, the choice of seedlings
When selecting seedlings, look at the attitude and the growing of trees, and then check for pests and diseases, should be strictly in accordance with design requirements, selection of seedling age young adults have a strong vitality of the plants should be used in the specification size slightly larger than the design specifications on the size, After pruning the plant in order to meet the design requirements.

2.1 tree stem form: the trunk should be straight, branched uniform, complete crown, avoid bending and bias, the trunk is smooth, without large nodules (greater than 20mm in diameter, the injury is not healing scar and prominent foreign body, color: In addition to color outside the leaf species usually leaves to dark green, shiny leaves and fullness: more leafy branches, the overall full, the main species formed dense foliage, bogey off the foot (feet off the ground refers branches over, no pests and diseases: yellow leaf is not usually made White, non-parasitic pests or a large number of eggs, age: 3 to 5 years seedlings, avoid small trees, old tree-ring method with the sampling.

2.2 shrub stem form: the low degree of branching and more is better, usually 1 to be three or more branches, branch point of not more than 30era, leaf color: green leafy leaf color was green, dark green, bright, color leaf want to pure color and fullness: shrub to many branches, leaves intensive full, especially in some ball games, or need to cut and all kinds of shrubs, to require a higher density of branches and leaves, no pests and diseases: the incidence of plant leaves from green turn yellow, white or colored patches show. observe whether the insects eat leaves bite, with or without insects, or a large number of parasitic eggs.

3 green land consolidation
Green to the order is not simply cleared away rubbish, weeds pulled out, the job is important because trees and other plants to provide good growing conditions to ensure the full root elongation. Therefore, should not be used in the construction of heavy machinery grinding pressure of the ground. we must first ensure that the root elongation balance, lawn, being the lowest survival of the root domain layer thickness of 15cm, a small shrub to 30cm, large shrub to 45cm, shallow-rooted trees as 60cm, deep-root trees Pi is 90cm. s Second, we must ensure that soil hardness. soil hardness to ensure proper root elongation and the maintenance of adequate ventilation and good permeability, to prevent soil compaction. Third, we must ensure that the drainage and permeability. So when you fill soil preparation to ensure that soil aggregate well-structured, if necessary, to set culverts and other drainage facilities. Fourth ensure proper pH. Soil is best value of 5.5 ~ 7.0. V to ensure that the nutrients. The best soil suitable for plant growth is the 45% minerals , 5% organic matter, air, 20%, 30% water.

4 to strengthen the quality control of construction processes
4.1 The importance of soil processing. The quality of the soil is directly related to the growth of plants in the future, its physical and chemical properties to laboratory analysis, from the pH, porosity, permeability and water permeability and water holding capacity in areas such as analysis, testing, and then take the appropriate disinfection, Base Fertilizers, foreign soil and other measures. In particular, the turn to dig the soil depth, foreign soil quality, and basal fertilizer was applied to the maturity level and the amount of flatness of the terrain must meet the relevant requirements. reposted elsewhere in the Research Papers Download http : / / www.hi138.com 4.2 point release line treatment. generally required position accurately, clearly marked, indicating the center point location of planting, planting trough marked edge, but they need flexibility in special circumstances, such as planting trees in the car with a sub- , when the case of street lamp posts, lamp posts due to keep 2m distance with regulatory requirements, put line to be flexible, adjust the distance between lines. Another point of street trees, as the roads on both sides of underground pipelines, fire hydrants, shops and other factors, often to the appropriate adjustments.

4.3 The planting hole, groove of the excavation. Planting hole, groove, as the seedling root system excavation, soil ball diameter, soil conditions to requirements, especially the cultivation of poor soil must dig deeper hole, and then Base Fertilizers and foreign soil, to create conditions conducive to plant growth in a small environment.

4.4 Good quality nursery stock. �� varieties of seedlings, plant type, crown width, height, trunk diameter, the size of the ball of soil, root development was so strict, select the design requirements, the growth of robust, non-mechanical damage, no pests and diseases good seedlings. �� foliage plants, leaf color should be bright, full foliage. �� Shop planted lawn grass grass block and volume size should be consistent, straight edges, weeds may not exceed 5%. grass blocks desirable for the thickness of soil 3 ~ 5cm, the grass layer thickness of the paper appropriate for the 1 ~ 3cm. �� sowing the lawn, flowers, seeds should be marked varieties, strains, origin, production units, weight, year of harvest, purity and germination rate, without pests and diseases. Since the introduction of the seed field should be quarantine certificates, the germination rate of 90% or more before use.

4.5 seedlings planted. Seedling planting root pruning should be carried out before, should be split roots, worms, root, root cut off too long, and crown pruning, preserving a balance to be above and below ground. Soil ball when planting trees, planting hole at the bottom to tread flat, bare roots, planting soil to fill hole into the bottom of the cone, fill layer when compacted, it is best to use the hoe ramming, without leaving any gaps, attention towards the viewing surface. planted with trees when the soil ball , non-perishable packaging must be removed. poured given 24h after planting, seedling root water must be poured within a given root in water, and to be drenched. After the timely replenishment should be based on local conditions, watering after planting in northern areas of not less than 3 times. cohesive soil, moderate watering, roots developed species, watering should be more, fleshy root trees, watering should be less. 5cm above the fixed support pillars of trees should be set fixed, fixtures should be neat and beautiful.

4.6 tree transplant. Transplant more than diameter deciduous trees in 20cm and 15cm diameter at breast height above the evergreen trees, trees should be transplanted. Pretransplant tree growth response to transplant trees, site conditions, surrounding environment, traffic conditions, etc. conduct Research, develop technology transfer programs. conditional region, can be mechanical transplanting. When you want to transplant the tree, the graft should be a year to determine the time before transplantation should be phased root cutting, trimming, good graft preparation.

5 implementation of the project supervision system landscape
Implementation of landscaping projects is landscaping project supervision system, quality management and control of security. With the construction of landscaping projects continue to improve, landscape engineering supervision system has entered the construction industry, landscaping projects. Landscaping project supervision is a high Smart technology services, follow the scientific guidelines to scientific approach, using scientific methods to work. Landscaping owner supervising engineer not only safeguard the interests of preserving the interests of the construction unit, so that law-abiding, honest, impartial, scientific, thus ensuring construction quality. supervisors landscaping project from construction to final acceptance can do the whole process of tracking, found substandard materials, processes, products, timely rectification to ensure that every aspect of landscaping works no problems, thus ensuring the Construction Quality Landscaping.

6 green conservation control
Landscaping works to strengthen the conservation management is the latter part of landscaping projects to ensure quality management and control. Landscaping seedling survival of post maintenance management is the key, if the landscape construction excellent, but green conservation management in place, will seriously affect the landscaping project landscape effect of project quality. If the late conservation and management in place, such as the watering is not timely, resulting in low survival rate of trees, tree stand is not strong, resulting in skewed tree planting, weeding is not timely, resulting in green weeds, a drug not timely pest control , leading to serious quality problems such as diseases and insect pests. Therefore, we must strengthen the conservation management of post-gardening project, to ensure project quality.
