Quinquefolia biological characteristics and application in Landscaping

Abstract: With the rapid development of industry landscape, urban green space can be used to reduce year by year, more likely to be seriously vertical greening. In the original premise of lack of green areas, to increase the amount of green to increase the visibility rate, should be based on the characteristics of plants can be extended to the spatial development, that is, vertical greening. creeper in the northern city a good choice for the vertical green material, it can make the city look even more glorious.

1 families and genera and ecological characteristics of
1.1 quinquefolia: parthenocissus quinquefolia planch Vitaceae, Parthenocissus spp.

1.2 Characteristics: deciduous vine, purple shoots, tendrils and leaves at branch ,5-12, top of the sucker large, palmately compound leaves, with long-handled, leaflets 5, quality thick, ovate elliptic long oval-shaped or inverted, long 4-10cm, apex acute, base cuneate, margin with large teeth, surface dark green, hairy back and a bit of white powder. cyme integrated conical berries nearly spherical, diameter of about 6mm, blue-black when ripe, slightly powdery, with 1-3 seeds, flowering from July to August, the fruit 9-10 mature.

1.3 Distribution: native eastern United States, China has cultivated.

1.4 Habits: hi warm climate, has a cold capacity, shade tolerance, anti-poor, strong adaptability to soil and climate, can survive even under dry conditions. In neutral or alkaline soil can grow and has some saline-alkali capacity, vigorous growth, disease resistance, pest less.

1.5 Propagation Methods: Propagation commonly used, whether it is perennial branches, twigs or article year students are easy to root. Inserted after more than 20 days to root, root callus that is cut, there lenticels roots, branches, the ground can see the wet roots cut out is the new strains. seeding, layering can also breed.

2 quinquefolia the superiority of Application in the Gardens
2.1 Propagation is easy: its propagation can be cutting, seeding, layering. Low investment, ease of management, drought-resistant, anti-poor, extensive management, without cutting, long life, if properly managed can live for decades.

2.2 The rapid growth of rapid prototyping: the road tolerable temperature of up to 50 ��. The annual growth of up to 2 meters or more, and larger leaves, larger coverage area. Whole plant area is small, the development of the air by the suction cup is to be and the slope of the good material.

2.3 fewer pests and diseases: for plants, strong resistance, suffer less disease and pest invasion, not susceptible to pests and diseases, and the sheep, goats do not eat its leaves and stems.

2.4 The development and utilization in the manufacturing liquor and drug development in the North: its fruit is wine, the root can be used as medicine, so the wine and medicine have been the prospect of widespread exploitation.

3 quinquefolia Application in the Gardens
Quinquefolia is a deciduous climbing plants, rapid growth, survival ability, coverage area, fewer pests and diseases, there is a strong suction cup, is a perfect vertical green materials.

It not only can be used for urban greening, but also for the town green or road slope greening. It in the spring and summer to form an emerald green barrier, autumn leaves turn yellow to red, is a big attraction in the fall, leaves can be comparable with the Fragrant Hills, which Green landscaping is not only good materials, is the color of, purification of the good material.

The main planting method:
�� high column. Stakes or poles in the vicinity of dead creeper planted several strains, it can rely on its own tendrils type sucker up growth, the green column can be formed or green cone, until the fall it can become a color column (cone or red color column (red cone, in fact, a great landscape plants.

�� With wall. With suction cups attached to buildings, rockery, retaining walls, the rapid upward growth, 2-3-year coverage of 80% ,4-5 years will be fully covered, but also in the process of growth can be pruned or Scroll human around the branches, to bypass the window growth of the building, much like a view to the green building, not only beautiful, but also reduce the temperature of the hot summer, people in the building has a pleasant fragrance and beauty. In the seven sets River City quinquefolia with vertical green everywhere, such as: Seven Coal Sales Company's office building, has planted more than ten years, it can change color with the season-phase. People call it: "Season wall" .

�� Lei Yuan style. In Li Jia, a low wall and iron fence, barbed wire next to the plant to form a green fence wall. In 2002 the city implemented Chaiqiangtoulv proposed units along the green slogans, blink of an eye, all the streets red brick, gray stone walls, all removed, have to install wrought iron fencing, planting quinquefolia.

2-3 years later, the iron fence into a green wall of plants, breathing, even more spacious and transparent, which greatly increased the rate of green biomass and green visible.

4, the management of Parthenocissus quinquefolia
4.1 As the saying goes: "one-third of seven in charge of plant protection." Parthenocissus quinquefolia but it can be described as the three in charge of seven plant protection. Planting should pay attention: when paired with other species, should take preventive measures, planting distance To further away, because it has a strong climbing ability, fast growth of other species to prevent the wound, which possessed the plant can absorb nutrients, and finally plant death caused by possession.

For example, a large slope in the green belt in Jilin City water a small amount of shrubs are dry wound quinquefolia nutrients and die.

4.2 attached to the wall for the growth of Jin, in the growth process, we should be pruning, Interlocking and around the branches, while the growth of artificially bypass the window to prevent light transmission rate of the room.

4.3 creeper bud in the spring before the dry dead branches should be cut to promote growth and better survival branch.

4.4 creeper planted in a large slope, and found weeds (such as amaranth, gray dishes over prostrate creeper growth, should be promptly removed weeds, to prevent the impact of aesthetics.

5 Conclusion
Quinquefolia Yin Qi Ju Panyuan of intensity, growth quickly, pest and disease �� and other advantages, Landscaping promising, it Zhengzhu small footprint, Xiang Kongzhongyanshen, it is easy Xiandao greening effect, Er Ju Jiang resistance to chlorine, with the seasonal changes in color, is green, landscaping, color of, purification of the rare good material for vertical gardening.
