About landscape dendrology. How to easily distinguish palm plants? Please tell me the characteristics that are easy to see.

Using Palmae plants to create plant landscape has its unique advantages, and the techniques used in garden design are also flexible, or the theme of the landscape or the arrangement of rows and columns are natural. Its tall, straight, spectacular, exquisite and handsome charm, together with mountains, water, ponds, stones, pavilions, terraces, corridors and pavilions, can form a very elegant landscape. Traditionally, it has been planted at the water's edge, such as Wangjiang Park and Jiushan Park. It is swaying in the wind and lonely, and the scenery is very charming. At the same time, due to the large leaves of Palmae, each leaf has an independent ornamental value and is very infectious. Palmae plants often do not branch and form a naturally shaped crown. For example, the crown of canary jujube is spherical; Malva has an oval crown, which dicotyledons and gymnosperms do not have. The plastic pruning of dicotyledonous trees is mostly maintained by manual pruning. Although it can reflect the beauty of individual shaping and group rhythm, it destroys the original natural beauty. Although gymnosperms have certain natural shapes, their crowns are mostly monotonous towers or cones. When using palm plants for landscaping, if we can plan rationally and design skillfully, we can achieve a high degree of unity of natural beauty, ecological beauty and artistic beauty, so that viewers can feel nature and transcend the secular.

2. Configuration of Palmae Plants in Wenzhou Gardens

Palmae plants are commonly used in Wenzhou gardens, including solitary planting, row planting, cluster planting and group planting.

2. 1 Single planting

Single planting is suitable for graceful single plants. When it comes to single planting, everyone will definitely think of a single banyan tree. Palmae, which do not know the single stem type, are highly concise and natural in crown shape, and are also suitable for single planting. Such as canary dates, Iraqi candied dates, Dong Brown, etc. Dong Brown has a beautiful tree shape and neatly arranged leaves. Although it has not grown into a tall plant, it still reveals a kind of greatness and domineering. Canary jujube has oblate diamond-shaped leaf marks on its stem, and its crown is green and spherical, which looks vigorous and tall. There is a canary jujube in Wenzhou University for the Aged, which has a history of 100 years and its stem is more than ten meters high, making it a beautiful scenery in the University for the Aged. Horticultural workers in Guangdong and other places did not treat the upper and lower parts of canary jujube uniformly, but trimmed it into thick upper parts and thin lower parts, forming this unique landscape, which is thought-provoking and amazing.

2.2 Inter-row planting

Planting is mainly used on roads or lakesides, which shows palm landscape characteristics while organizing people's flow or guiding people's direction. Suitable for planting are Pukui, Kuihou and Hai Yin Jujube. On the east side of the Music Station in Zhongshan Park, there are plantings of Pukui along Huayuan Road and Jiang Bin Road, and several rows of Hai Yin dates in Century Square, forming a magnificent momentum. Planting queen sunflowers in front of some large hotels, such as Victoria Hotel and Olympic Hotel, not only covers the rigid straight lines and corners of the building, but also softens the main building, making it elegant and quiet, bringing beautiful scenery and happiness to people.

2.3 Cluster planting

Cluster planting is a planting method that combines more than three trees of the same species or several trees together. Cluster planting should not only show the beauty of the group, but also take into account the beauty of the individual. Generally, several queen sunflowers are planted in the flower beds of Fei Xia North Road, and Berberis purpurea and horseshoe lawn are planted under the trees. The whole flower bed is rich in color, while the leaves of the queen sunflower are drooping green, fluttering with the wind, and the viewing effect is excellent. In the large area of tall fescue lawn at the north gate of Ma 'anchi Park, queen sunflowers are planted in groups of three or five, and then Ligustrum lucidum with small leaves trimmed into big balls is placed, and scattered stones are placed to form a patchwork, yearning for life and poetic garden landscape.

2.4 Group planting

Group planting is the group beauty of groups composed of different species. At the foot of Xunshan Mountain, on an open green land of about 2,000 square meters, many palm plants have been planted, with Hai Yin jujube with a height of 5-6 meters as the main dry tree species, canary jujube with a height of about 2 meters, Washington palm and Budi coconut with a height of about 1 meter, and several groups of beautiful plants, bright red mussels and lake rocks are dotted in the open space, which not only has rich landscape layers, but also forms a rich tropical scenery.

Because of the unique landscape effect of Palmae, it is necessary to avoid mixing with other dicotyledonous broad-leaved trees, otherwise it is difficult to express the individual beauty of Palmae, and it is even more necessary to avoid mixing with conifers, because they represent two different landscapes, tropical and temperate. In a green space in Wenzhou, there is a large lawn with many palm plants planted on it, which is a tropical scenery. But the fly in the ointment is that several white orchids are planted in the middle. Although the white orchid is also a tropical tree, it is completely different from palm plants in leaf shape and texture, and looks neither fish nor fowl.

3. Palmae plants suitable for planting in Wenzhou

In recent years, due to the development of landscaping, more and more palm plants have been introduced and cultivated. When planning and designing, we should first consider whether the ecological conditions of the selected palm plants can be met. Temperature is the most important factor, and sometimes we should consider the difference of microclimate. Palm, mallow, canary jujube, Iraqi jujube and other tree species have been planted in Wenzhou for decades, and other successful tree species have been introduced, such as Washington palm, Hai Yin jujube, Budi coconut, East palm, long-spike eggplant, short-spike eggplant, queen eggplant, brown bamboo and Stipa grandis. Among them, Washington palm can withstand the low temperature of MINUS 12 degrees, and Budi coconut is also safe at MINUS 22 degrees. In some European-style buildings, sunflowers and fake Penang olives are planted at sunrise, and due to microclimate conditions, they can also safely overwinter outdoors. Anemone brevispike and Anemone longispike are not cold-tolerant, so they should be planted according to local conditions.

In a word, at present, more and more people like to introduce Palmae plants, which requires our landscape workers to fully consider the ecological habits, ornamental characteristics and configuration techniques of Palmae plants, and constantly explore and sum up experience, so that Palmae plants can shine brilliantly on suitable land in our province.
