1、 On aquatic plants in Taizhou City in the application landscape Summary of the types of aquatic plants, analysis of its landscape value and ecological significance, with aquatic plants in Taizhou City, water gardens in the application, Taizhou City, sums up the current problems in the application of
2、 aquatic plants, aquatic plants in the landscape construction of application recommendations. Keywords aquatic plants; landscape; applications; Jiangsu Taizhou Aquatic plants because of its beautiful shape, rich colors and variety, is widely used in urban gardens and water features in the layout, it
3、 not only beautify the environment, but also clean water is essential for the modern garden landscaping materials 1, 2 . With the construction of the scientific landscape and culture to improve, to adapt to the construction of garden cities, the goal of eco-garden city, urban landscaping and public
4、attention by the government, more and more application of aquatic plants. Growing urban landscape , aquatic plants in the urban greening will play an increasingly important role. will continue to expand the application of aquatic plants to the park landscape, wetlands, ornamental plants, river beaut
5、ification, water purification, green area, and many other. With the last few years, Taizhou City park construction, aquatic plants in Taizhou City in the application landscape showing a vigorous momentum of development, especially the new development and construction of scenic spots and Garden Expo
6、Fengcheng River project, more and more people to Taizhou enjoy the ocean waves, flowers natural beauty. A type of aquatic plants Refers to the growth of aquatic plants in the aquatic environment in the plant. Many of Chinas water, rich in aquatic resources, there are only 300 species of higher aquat
7、ic plants, according to the most common classification of aquatic garden, their lifestyle and morphology can be divided into very water-type, floating leaf type, floating type and submerged in 4 types. Emergent plants roots in the mud, the stem elongation of the water, some species with hypertrophy
8、of the rhizome or root system has developed in the aerenchyma of water depth and plant height for general adaptability, suitable for tall plants water capacity of slightly stronger. and then force flower, reed, Arundo donax, Shuicong and other tall plants adapt to water depths of up to 60cm; arrowhe
9、ad, sea-life flowers, yellow iris, cattail, Lythrum plant vegetables around the middle of the plant to adapt to 55cm depth; Mosaic reed, Yuchan flowers, rushes, and so meet the water depth in Alisma 10 30cm. floating plants root in the mud, leaves floating on the water or slightly out of the water n
10、ear the surface when the flowers of these plants the petiole or stems, leaves the spongy tissue more developed, there are a lot of storage air on the depth of floating-leaved plant adaptation in general is better than the emergent plants, and vary by type, such as the Gorgons appropriate water depth
11、 of 1.5m, Link to up to 3m, when the plants grow to a certain extent can be quit a floating plant, no longer subject to depth restrictions roots of floating plants drift in the water, leaves floating on the water completely, you can drift with the water, the location of the water is not easy to cont
12、rol most with foliage-based, they can both absorb water minerals, but also inhibit the growth of algae, such as duckweed, water turtle, water hyacinth, etc. submerged plants roots in the mud, leaves and stems submerged in water, with lake aquatic vegetation exists to prevent the upper body of water
13、power disturb the wetland bottom, effectively controlling sediment nutrients to the water release, cleaning up water quality or layout of the underwater landscape of fine plant material and they can during the day and produce oxygen, help the chemical composition of the water balance and promote the
14、 growth of fish, such as Formosa algae, Ceratophyllum demersum, Vallisneria and so on. 2 aquatic landscape value and ecological significance 2.1 Landscape effects Aquatic plants can not only foliage, flowers, smells, but also enjoy the shine reflection in the water. Floating around the curved shore
15、fragrant, round shadow covered Huachi, Boming Nymphoides leaf flutter, wind-heat Ping flowers and the poem describes the aquatic scenery gives a fresh, comfortable feeling from the space point of view, wide body of water, easy to produce dull feeling. In addition to using kiosks, bridges separating
16、surface structures, but also with a combination of aquatic plants and ornamental plants to enrich the water and separate the different texture of the ground and enclosed space, while in the water environment, the use of cloth in the water around the tree planting forests, grasslands, form a shade, q

Ecological value of 2.2 The current declining water resources, water damage to the ecological environment worsening, make full use of aquatic plants for improved water, reduce pollution, a significant role studies have shown that aquatic plants can absorb, nutrient enriched water and
18、 other elements that increase The oxygen content of water or inhibit harmful algal blooms, sediment nutrients to the water to stop the re-release, which will help water biological balance. Aquatic higher plants can effectively purify the eutrophic lake, improve self-purification capacity of water bo

23、 recent years, aquatic plants in the urban landscape on the application has been rapid development, creating more aquatic forming system, but because of aquatic plants in Taizhou City park applied research to prepare a serious shortage of applications mainly in the following problems. First, the app
24、lication of aquatic plant species diversity is not rich. Although the types of aquatic plants, 300 species, but the landscape in Taizhou City, only the application of more than 20 varieties, on lotus, water lily, and then force the majority to spend and a few other varieties. wetland landscape is mo
25、notonous, the lack of layering, so nothing new landscape of water, lack of local characteristics, there are many varieties are not introduced and domesticated, most of the ornamental value of the water plants and flowers have not yet been rain for a long time lanterns and other applications. evergre
26、en aquatic plants application of a small, uneven landscape seasons, winter water view single. Second, the landscape configuration of aquatic plants is too monotonous. aquatic landscaping, although great attention in recent years, rapid development, but on the whole, plant configuration is relatively
27、 mechanical and simple, nothing more than massive, banded, and other combinations like several forms of use. aquatic species configuration monotonous, so the lack of layering, making the water landscape is nothing new. Aquatic species will lead to monotonous birds, fish, lack of cover habitat, resul
28、ting in a lack of vitality of the entire water body ecology, landscape poor results. Third, the application of the matching support of aquatic plants is not enough. Construction workers on the aquatic plant growth habit not very familiar with the anti- season of construction losses. garden designers
29、 do not know enough of the aquatic plants, causing their application in the design of more conservative, aquatic plants can not fully play the role of engineering in water features. maintenance personnel management of aquatic plants is more extensive, because lack of experience, can not be effective
30、 pruning, fertilizing, pest control and other normal maintenance, resulting in the growth of aquatic plants is not robust. There is a lack of professional production base of aquatic plants, the basic dependent on from Shanghai, Hangzhou substandard provinces transferred. Fourth, applied research on
31、native aquatic plants is not currently a lack of local native aquatic resources investigation and development of applied research. Meanwhile, the inflow of foreign species of the lack of awareness of the dangers, such as highly reproductive of water hyacinth, large drift, with its water purification
32、 function has not been effective, indeed soaring disaster. In winter, they sink to the bottom of the aging body, precipitated into eutrophication, causing secondary pollution. 5 accelerate the development of aquatic plants in Taizhou City, the proposal 5.1 diversity of aquatic species Landscaping an

Naturally the water level of the configuration of aquatic plants should be scattered along
37、 the waterfront edge or point cluster planting or planting, plants, colors, body mass and the lines can be varied, avoid planting style skirts, rule-based body of water enclosed by the rules should be in the water the planting slot, slot aquatic plants should not be too much to prevent the spread of
38、 damage to the overall landscape of plants. tortuous stream configuration is more particularly the way on plant quality, color, line requirements are high, need to consider when planting pebbles placed, usually positioned at the point of the plant before planting to slow the flow of water on aquatic
39、 plants produce long-term impact of the adverse effects on plant species configuration to form emergent, submerged echoes, aquatic, terrestrial plant allocation pattern of coordination. type configuration should also pay attention to water wetlands with trees and shrubs and trees leaf color configur

42、 plants are not the desired effect. Plant construction should be in accordance with the ecological habits of different plants, water depth and water level changes in circumstances set deep water, the water area, shallow planting, such as water lily, etc. about 1.2m deep water adapted to the growth o
43、f cattails, mosaic and other accommodation in Lo Tik 20 30cm shallow zone growth, Iris, Lythrum vegetables grown in the sea and land border areas. different water requirements of plants there are also differences, such as the water lily plant, maintain water depth in the 50 60cm, when the leaves sur
44、faced, with the the growth of plants need to gradually raise the water level, flowering to maintain water depth 70 80cm, l must be added before freezing the water level, water depth stabilized at 90 100cm, so the water lily can live through the winter, usually aquatic plants, the total area of ?the
45、surface area should be 1 / 3 to 2 / 5, not too crowded, water features can be formed, with the continuous growth of aquatic plants, tiller, water will become increasingly crowded, which requires manual trim, pumping thin, if necessary, also in the bottom cofferdam with masonry to prevent the spread
46、of its underground stems and only maintain a certain empty the water, in order to reproduce the beauty of wave ripples.
