Form the famous historical and cultural city and a famous garden city - Hangzhou. The ancient Especially with the recent large-scale renovation of the West Lake, Hangzhou Glowing mountains and scenery was even more attracted worldwide attention. According to statistics, as of 2005, greenbelt area of 30,229 hectares, 37.07% green coverage rate of green land 33.75%, 9.89 square meters per capita public green space. However, after a scenic tour major parks of Hangzhou, Hangzhou, although you will find a beautiful, beautiful scenery, but because of historical conditions, the use of landscape plants most similar, in particular forest and the forest edge of the ground vegetation, the main use book with evergreen grass, grass and shade of rhododendrons auspicious, octagonal gold plate, water,UGG shoes, gardenia, etc., while highlighting the characteristics of evergreen, but can not meet the plant diversity, hierarchy and ornamental needs.
every New Year's Day, junction, the Hangzhou embellishment into a sea of flowers. But the fly in the ointment is that the application of these festivals flowers, most of the viewing period is only ten days. According to incomplete statistics, Hangzhou Garden of Cultural Heritage for the layout of the park area each year to spend the time up to five, six million pots, plus the cost of transport, management and protection, the economic costs can be imagined, this is a Government no small burden.
order to gradually improve and solve this problem, the end of 2004, Hangzhou Garden City Diversity of Cultural Heritage with application of new materials technologies, focusing on the introduction and promotion of flowering perennial to be constructed Chunjing Autumn
information, our resources are very rich in flowers, common on the ball of hundreds of species of perennial flowers.
perennial flowers and more with a cold, drought, infertile soil resistant, resistant to insect pests and strong features. Generally able to grow normally in all soil and perennial flowers, breeding easier, because root system, strong sprout, cutting or seedling tiller up to 20 times the propagation coefficient. Then you can usually bloom in spring sowing. Moreover, survival of the ball after planting perennial flowers in general do not need special management, which can bloom year after year. Because management is extensive, less labor, less investment accordingly. If these perennial flowers can fully play its role, not only can save green capital, you can also make the city residents can watch the colorful perennial flowers, more rich in scenic Hangzhou been the relatively monotonous plant species. Bureau of Hangzhou City Park article
selected West Lake Park and the long bridge as the introduction of the test area Wansong College, organized people to a similar site conditions in Hangzhou Shanghai study tour, according to Long Bridge Park and Wansong College's own environment and design introduced species, the number and configuration of the implementation of the program, the ball has introduced new varieties of perennial flowers and shrubs, etc. 100. Mainly new varieties of foreign and domestication of wild plants mainly from the color, shape speaking, very close to nature, the process of landscaping in the configuration also strive to create atmosphere.
Long Bridge Park through the transformation of West Lake in 2002 and became full-open park. In order to change the original monotonous and thick trees, mainly in the forest edge and the edge of water features high and low levels of acquired reading glasses to highlight the rich landscape. Park opened up a total of eight flower border: Long Bridge Park north entrance decorated with flower border Square Museum of Art, Tang Yun, Tang Yun Museum Plaza lake flower border, flower border lake island, maple flower border, Hemerocallis flower border , West hotel parking lot flower border and flower border, a total of 92 selected species, with reference to the natural landscape of wild flowers in forest edge areas of natural growth state, through the art of refining and natural style designed with flowers, and to highlight its varied group image color and fullness. Museum Square flower border with Tang Yun example, the main habitat for the L-shaped flowers, due to lack of front light strip plots, on the set of trees, so the shade, mainly wild plants, although not as good as many of Xi Yang Flower Border color rich, but still wild passengers. After the level set by the front, scattered layers. Musella lasiocarpa and do something with King material to extend the level of banana, making the overall structure is not significant in isolation. Posterior surface of the larger blocks of flower border, the terrain full, rich background, light enough, consider the many tourists around, designed to be multi-faceted ornamental flower border, around the middle of high-low. Taihu point of view and use, in its configuration ornamental grass to soften the back of its hard texture. Because it is arranged in the flower border in the winter, so the material used mainly in the regular green leaf plants. Bright colors, rich colors contrast, and a small amount of perennial flowers in different seasons you can present a different view.
After nearly a year of practice, and many varieties of perennial flowers in the park the ball introduction and configuration is quite successful, and demonstrated its natural beauty, appreciated by the visitors, but we also found some problems , summed up some experience, is how to further promote the development of perennial flowers and some suggestions for your reference.
1. Introduction and promotion of urban greening plants disadvantage
plant introduction and promotion of urban greening is a highly professional work, there are pros and cons of plant introduction in itself, particularly in the current large-scale introduction of circumstances, should cool analysis, the correct treatment, to ensure the healthy development of plant introduction and promotion to reduce and avoid the introduction itself may lead to non-adaptive.
The introduction of the ball from Shanghai to try to choose perennial flowers and native species adapted to ecological conditions, but because of excessive use of new varieties, information is relatively scarce in the characteristics of the limited introduction is often confined to the general description, such as shade, half shade tolerance, soil acidity or alkalinity, the lack of more detailed and specific scope of application and cultivation measures, and applications in plant configuration information between the even more essential. New varieties of employees do not know much, leading to the failure of technical staff in the configuration according to local conditions, some species with the environment is not appropriate to the site, the reading glasses arranged in December 2004 to complete, in April 2005 and October has been gradually enriched adjustment, replacement of some species, so that the whole flower border effect has been more fully reflected.
which varieties are not suited to:
⑴ Bergenin hot summer drought intolerant, the basic can not be over-summering in Hangzhou;
⑵ Musella lasiocarpa open intolerance Hangzhou Winter The extreme low temperature. Since last winter, extreme low temperature of minus Hangzhou seven to eight degrees, so that Musella lasiocarpa was hurt by the freeze, due to the vitality of its own strong following spring and gradually germination, but froze to death rate of nearly 1 / 7.
⑶ beautiful evening primrose is easy because of its habit of lodging in Hangzhou, abundant rainfall in spring and rotten leaves often appear during the rainy season the situation has seriously affected the reading glasses effect.
⑷ woolly stachyose better in autumn and winter, but because of its soft leaves of a domesticated hen apt to encounter rain rot, significantly affect the landscape.
⑸ pineapple mint is also similar to the Soviet Union's problems woolly water, perishable.
⑹ Chiba Achillea autumn and winter effects are good, but it is also easy to lodging, rotten situation,UGG boots, difficult to manage.
⑺ Phlox subulata difficult to spend the summer heat, likely to die.
2. to support the varieties of the introduction, propagation and cultivation and management techniques
supporting the promotion of a new species from the species to the widely recognized, there will be a test to the propagation from the promotion process, which needs to be green and technology departments and administration support. Perennial flowers because of its diversity of germplasm resources and existing cultivars bred a rich variety of types (ornamental varieties has reached 20,000 kinds, such as Iris are about 300 species of plants. Hemerocallis growth types are high, in the different short, colored purple, yellow, meat, orange, jasmine, yellow and other colors, the domestic since 1974 since the introduction of 71 hybrid seeds have been hundreds of varieties), which requires different according to the local landscape ecological attractions the introduction and testing and screening. Characteristics of its management should also make corresponding set of technical measures, in view of high value perennial flowers, but summer dormancy or winter dormant species,UGG boots cheap, cultivation is necessary to study multiple cropping, intercropping technology.
large area of the ball perennial flowers the first time used in the West Lake, Phoenix Mountain Management Office of the technical staff, although aware of the work of the task is arduous as the introduction, but much of its growth habit control its conservation and management measures are lagging behind, which often brings some of the technical operation of the loss. In particular, not enough time for pruning, often leads to excessive growth and lodging some species. Such as the Asian Ju-lit place in the growth of good, little pest, but failed to make timely pruning, leading to excessive growth, once the leggy, the lower branches off the main bar, and easy to lodging. Until then bare left after cutting the main stem, even if their budding ability, but the landscape is less desirable in a certain period.
3. follow the characteristics, local conditions, widely
Landscape in Art and perennial flowers, in principle, to follow the ecological characteristics of perennial flowers, in the promotion of the use in harmony with the surrounding environment, and feature match.
perennial flowers grown in the open field for their anniversary, management, greenhouse flower cultivation and not as sophisticated, so the surrounding ecological factors (moisture, temperature, soil and other site conditions, etc.) have certain requirements and adaptability Select the appropriate ball flowers, flowers suitable growth as far as possible, not over the pursuit of wild, slow Introduced species due to the current from Shanghai, Shanghai, alkaline soil, acidic soil in Hangzhou are mostly made in the soil when planting a certain degree of improvement, resulting in most of the introduced species that grow well.
different green environment, its functions and requirements are different, so the planting of perennial flowers design of the ball is different. Such as green streets, the main function is to shade and beautify the environment, without affecting the traffic line of sight of the premise, using a variety of flowering shrubs and perennial flowers combine the ball, both rich streetscape, but also bring to the pedestrian feel relaxed and happy ; can also select some strong resistance, plant morphology compact flowers, such as Ophiopogon, sorrel, etc., with open eyes, decorative effects and other characteristics. Green in the park, and its main function is to beautify the environment, for the majority of recreational visitors a beautiful place. In this context, forest edge, forest can be selectively coupled with ball flowers, scattered high and low, rich forms, creating elegant natural landscape.
4. ball perennial flowers and broad development prospects
our species through the introduction of 100 kinds of adaptability observed nearly a year, found the ball perennial flowers, ornamental grasses and the new priorities of small Shrubs or more compatible with the overall climate in Hangzhou, the overall results are good, worthy of promotion. Meanwhile, as people's material and spiritual development and improvement of the ball perennial flowers in landscaping applications,UGGs, development prospects, and garden construction by the United States to focus on large groups of individuals in the direction of the United States to further clarify the garden to plant- oriented, while the plant is stressed that the overall design, group planting, requiring three-dimensional configuration, in time, requiring changes in the present focus on the different landscape effect, this is the rapid development of modern landscape is an important feature. It is this characteristic of modern gardens promote the development of perennial flowers, perennial flowers in the garden to improve the status of the construction. Application of perennial flowers in the garden that has a culture, for many years the growth, maintenance and low cost fast convergence, group, strong function, such as the characteristics of a large ecological benefits, and a wide range of flower shapes and colors rich and varied, is to improve the status of the city to spend the Spring and Autumn short to achieve three quarters of flowering plants important to the layout of a class of materials, application prospect is worthy of garden flowers material.
summary, introduction and promotion of the ball perennial flowers for the project, necessary to build West Lake scenic area with green space green space integration, urban green space and suburban green space complementary to the park, the combination of green space and urban green space, and gradually form a system, improve the green space system.
perennial phlox flower tolerance test Kefu Paul is a perennial herb, stout erect stem, leaf, leaves on the Department of Health and stems, often has three wheels Health, apical large panicles, about 15 cm diameter, flowers dense, colored red, purple, pink, complex color and other colors. Cold, happy light, avoid hot, rainy summer. For flower beds, flower border, ground cover.
Division Iris Iris Iris, perennial herb with short rhizome, pale yellow; plants were lower, about 30 ~ 40 cm, Jian Ye-shaped, papery, pale green; stems slightly higher than the foliage, single or two branches, flowers blue-purple, flowering in May. Zhi Cong used in gardens, flower arrangements throughout, wet planting stream side of the pool the lake is also important to be plants.
hi beautiful evening primrose light, cold, avoid stagnant water; plant height of 50 cm forming, rod weak, easy to lodging, growing attention to shape cutting, pruning after the second flowering. Flowering summer evening to open the next morning, pleasant aroma, suitable for garden afforestation purposes.
