What are the types of flowers and trees in greening projects, and what are the quality requirements

The commonly used tree species for landscaping are divided into south and north according to different regions.

1. In the north, such as in Jinan, commonly used tree species (including trees, shrubs and vines) are: Chinese poplar, plane tree, poplar, weeping willow, willow, cedar, dragon cypress, sprinkling golden cypress, paving cypress, etc.

2. In the south, such as in Fujian, the tree species commonly used for greening are: camphor, ginkgo, three fir (including metasequoia, pond fir and lupus and their cultivars), osmanthus, Huangshan luan, marsh pine, soapberry, zelkova, magnolia, thin-shelled hickory, juniper, cherry blossom, Jiangnan oil fir, oil fir, southern hemlock, long-bud hemlock, spike fir and so on.

3. Experts believe that although wind resistance is an important criterion for the selection of urban garden tree species, it cannot become the only criterion, and the adaptability, diversity, landscape, and functionality of urban garden trees need to be comprehensively considered, and the selection of tree species and plant configuration should be done scientifically and reasonably.

According to the purpose of greening, garden trees can be divided into garden trees, shade trees, street trees, forest belts and forests, flowers and shrubs, climbing flowers and trees, ground cover plants, hedge plants, potted pile trees, and cut flower trees.

1. Garden trees are trees planted in courtyards, gardens, green spaces, and parks, such as cedar, ginkgo, etc.

2. Tingyin tree refers to the dense crown of the tree, forming a large green shade, such as catalpa, plum, etc.

3. Street trees refer to trees planted on both sides of the road, such as weeping willows, poplars, etc.

4. Forest belts and forest trees such as poplars and black locusts.

5. Flowering shrubs such as forsythia and cloves. Climbing flowers and trees such as grapes, Fufang vines.

6. Hedge plants such as ligustrum and pearl meadowsweet.

7. Ground cover plants such as paving cypress and Fufang vine.

8. Potted pile trees such as five-needle pine and elm.

9. Cut flowers such as moon season and peony.

(1) Garden trees.

Trees planted in gardens, gardens, green spaces, and parks, such as cedars, ginkgo, magnolias, cherry blossoms, etc.

2) Shade trees.

The canopy is dense, forming a large green shade, such as plane tree, acacia, tomentosa, etc.

3) Street trees.

Trees planted on both sides of the road, such as weeping willows, ash, camphor, acacia, horse chestnut, luan, etc.

4) Forest belts and forests.

In the range of more than 200 meters in length and 20-50 meters in width, more than 3 rows of trees are planted to form a forest belt. Commonly used tree species such as poplar, luan, pentagonal maple, acacia, black locust, etc.

5) Flowering shrubs.

Such as bauhinia, crape myrtle, cloves, hibiscus, spring, elm leaf plum, sea tung, June snow, etc.

6) Climbing flowers and trees such as Lingxiao, wisteria, grapes, Fufang vines, etc.

7) Hedgerow plants.

Such as boxwood, ligustrum, dragon cypress, red leaf barberry, etc.

8) Ground cover plants.

Such as Luo stone, ivy, paving cypress, Fufang vine and so on.

9) Potted pile landscape trees.

Such as five-needle pine, medlar, banyan, firethorn, elm, ginkgo, osmanthus, mosquito mother, privet, plum blossom, grapes, etc., can make bonsai or potted plants.

10) Cut flower plants.

Such as plum blossom, wax plum, silver bud willow, rose, peony, lilac, citrus bone and so on.

First, the characteristics of Weimin garden engineering mainly have the following four:

1) The development of urbanization has brought opportunities for the landscaping industry.

2) With the continuous increase in the investment of municipal departments at all levels in municipal gardens, it is expected that with the further advancement of urbanization, the growth rate of urban landscaping construction is expected to accelerate in the future.

3) Enhance the quality and brand awareness of garden enterprises, and enhance the competitiveness of enterprises;

4) It is conducive to further standardizing the landscape engineering construction market, has a positive demonstration and guiding role in the construction of garden digging projects, and promotes construction enterprises to create more and better landscape quality projects, so as to better meet the needs of the city's ecological civilization construction.

Second, the quality of the project should meet the following standards:

1.National, local or professional quality inspection standards and design standards; 2.design drawings stipulate;

3.The process construction method and quality perception meet the requirements of Party A.

According to the role of trees in landscaping, they are classified as:

Tree viewing. Such as: osmanthus, cedar, maple.

Shade trees. Such as: sycamore, ginkgo.

Trees. Such as: chongyang wood, camphor.

Groves and forests.

Such as: tung tree, rhododendron.

Flowering trees. Such as: magnolia, plum.

Vines. Such as: leaf flowers, dill.

Functional needs of flowers and trees in landscaping: ornamental flowers and trees cultivated in landscaping have their own functional needs and planting purposes, and different uses have their own special shaping and pruning requirements, and different shaping methods will form different ornamental effects.

The main requirements of street trees are neat, generous, shading, reflecting the urban style and other functions, and the operation is convenient and the style is unified in shaping and pruning. Shade trees should have dense branches and leaves, a broad crown, and a natural tree shape. Solitary trees, if planted in the main scenic spot or regular garden with many visitors, are generally located at the visual focus, play the role of the main scenery composed of the garden green landscape, pruning should be fine, and combined with a variety of artistic modeling, so that the garden is colorful, novel and chic, full of vitality, and play the greatest ornamental function to attract visitors; If it is planted in the corner with fewer visitors, or in a small amusement park and scenic spot with the simple nature as the main style, it is advisable to keep the rough and natural shape of the tree, so that the visitors can have the feeling of returning to nature and fully appreciate the natural beauty.

Flowering shrubs should be full of flowers and bright flowers.

Hedgerows should be trimmed in a regular manner to form a variety of geometric patterns.

Some of the objects of landscaping projects are living organisms. Through the planting and matching of various color plants, flowers, trees and turf, and the special functions of various seedlings are used to achieve clean air, vacuuming, cooling and sound insulation, and create and beautify the living environment. If it is said that any building pays attention to beauty, then the landscaping project pays more attention to artistry in landscape sketches, plant configuration, classical architecture, etc., and its effect should give people a particularly beautiful feeling.

This point may be difficult to achieve in some design parts, and it is necessary to realize the best concept and realm of design through the creative labor of engineers and technicians. For example, rockery stacking, Huangshi revetment, micro-terrain treatment, etc., the same design drawing, on the adjacent construction site, due to the different skills and proficiency of the construction personnel, the artistic effect and momentum are completely different, and the contrast between the perception is large, which puts forward the professional in-depth requirements for the engineering construction personnel and the special treatment requirements for the beauty of garden art.

Landscaping is a place to provide people with a good rest, cultural entertainment, close to nature, and meet people's desire to return to nature, and is an important measure to protect the ecological environment and improve the urban living environment. Grid method: The grid method combines the design of the site with the calculation of earthwork.

The specific working procedure of the square grid method is as follows: make a square grid to control the construction site on the topographic map of the construction site with contour lines, and control the construction site according to the design intent, such as ground shape, slope aspect, slope value, etc. Determine the design elevation and construction elevation of each corner point, divide the fill and cut area, calculate the amount of earthwork, and draw the excavation plan and site design contour map.

The earthwork construction is carried out according to the construction organization design arrangements such as excavation, transportation, filling, and ramming, so as to meet the requirements of the construction site.
