Which green seedling varieties are the most promising?

Which green seedling varieties are the most promising in the future: starting from the second half of last year, the green seedling market in most parts of the country began to rise steadily, and the prices of green seedlings, medium-sized engineering seedlings, and large-sized seedlings all increased by varying degrees. Especially at the beginning of this year, reports about the rise in seedling prices across the country are common, making the development of seedlings a hot topic, sweeping away the sluggish situation of the market in previous years, ushering in a new round of dawn of the development of the industry. China's green seedling industry in the next few years or even decades, which seedling products are the most promising?

Careful analysis of the development of Sichuan green seedling market, it is not difficult to find that many of the best-selling or some traditional seedlings, for seedling growers, the planting risk of traditional seedlings is smaller. However, from the perspective of long-term development, the seedling market needs to constantly introduce new varieties of seedlings and supplement new blood, so that the landscape can continue to bring forth the new and create more garden beauty.

Keep an eye on the standard seedling

Greening is a process of continuous upgrade. with the improvement of economic conditions and living standards, people put forward higher requirements for the variety, specification and quality of landscaping seedlings. With the further deepening of greening, the seedlings will develop in the direction of refinement and personalization. In my opinion, there will be broad prospects for standardized seedlings and styling seedlings in the next few years.

First of all, standardized seedlings, this kind of seedlings have the same specifications, high survival rate, reasonable density in the planting process, and have higher requirements in DBH, crown width, plant shape and so on, which can produce good ornamental effect. This kind of seedlings can be used for public greening and courtyard planting. There is also a kind of new, strange and special shaped seedlings, such as crape myrtle, cherry blossoms, ginkgo, sweet-scented osmanthus, Luohansong and so on, which need to be shaped according to the tree system, with high technical content and long cultivation time, and have attracted much attention in recent years. it has high ornamental value and profound meaning. Such as multi-layer grafting of Robinia pseudoacacia, high grafting of Populus tomentosa, high grafting of Sabina vulgaris, cultivation of juniper seedlings and so on. Mainly used for villas, high-end residential areas, large-scale tourist attractions, municipal greening.

At present, there are still many varieties in the greening market that are undervalued. Magnolia, Populus tomentosa, Tripterygium and Chimonanthus are good landscaping varieties, but the price is lower in most greening markets. For example, Magnolia Magnolia with a breast diameter of 8 cm can sell for 200 to 300 yuan, but in fact it is only a few dozen yuan. For this undervalued variety, it should be developed through a variety of ways, such as du Ying, which has a large quantity and low price in Jiangsu and Zhejiang, but if it is introduced into Guizhou, a reasonable price can be obtained.

For a long time, the trees used in the north have been very monotonous. in recent years, with the introduction and development, many tree species have been excavated and will play a more and more important role.

Among the deciduous trees, I think silk cotton has strong adaptability, cold resistance, water, moisture, drought and saline-alkali resistance, and can be planted from northeast to northwest. The three-north shelterbelt headquarters has designated it as the main afforestation tree species, and it is expected to use a lot in the next few years. Silk cotton can also be grafted with evergreen species such as Hokkaido boxwood, big-leaf boxwood, Fufang vine and so on. At present, its price has gone up, the seedling with a breast diameter of 5 cm costs 60 yuan, but there is still a lot of room for increase.

The second is the incense tree, which has been proved to be safe to winter in Beijing. At present, the incense tree planted in Beijing Botanical Garden is growing well. The tree species is a tall tree, the shape of the tree, the leaves are very beautiful, the wood is also very good, can be used as a northern street tree, but also a national first-class protected tree species, very precious.

Seven-leaf tree is also a good choice, it is a world-famous street tree, Beijing now has a small number of applications, growing well. However, at present, there are very few large-size seven-leaf trees with a breast diameter of more than 10 cm in the market, and the number of seven or eight centimeters in the nursery is large. The price of an seven-leaf tree with a DBH of 9 cm is nearly double that of 10 cm. By next year, 50, 000 Buckeye trees with a diameter of 10 cm at breast height will enter the market in Henan, but demand is expected to fall short of supply. In addition to the seven-leaf trees, such as red fruit holly, except bran trees and other large trees have been proved to grow well in Beijing, there will be greater demand in the next few years, the price will gradually rise.

Five types of trees have broad prospects.

With the increase of project volume in Northeast China this year, there is a great demand for seedlings, among which I think five varieties have the broadest prospect. One is the native tree species. Many native tree species in Northeast China are often ignored because of their slow growth and difficult reproduction. And some urban construction departments blindly introduce exotic tree species, but also into the misunderstanding of greening. Nowadays, many people begin to turn their attention to native tree species, such as Magnolia officinalis, Quercus angustifolia, Quercus liaotungensis, Quercus mongolica and some native varieties of Aceraceae, which are adaptable and will play a leading role in greening.

Second, flowering shrubs and fruit seedlings. If the city wants to be really beautiful, it is necessary to use flowering plants to decorate, such as peach, apricot, pear, Hawthorn and other small trees that spend a long time in the greening market. However, if some tree varieties such as honeysuckle can be properly applied, the greening effect will be more abundant.

Third, color-leaf trees, golden leaves in spring, yellow-green in summer, golden in autumn, and bright leaves throughout the growing season. It has a broad application prospect in urban leisure parks.

Fourth, shade-tolerant tree species, now the city is full of high-rise buildings, the city is in urgent need of shade-tolerant tree species, such as pod, Liaodong Wei spear and so on.

Fifth, precious tree species, such as Taxus mairei, ginkgo biloba, Huashan pine and so on, most of which have high price and slow growth, but have high ornamental value and play an embellishment role in urban parks. Local tree species are the main attack in the city, and the introduction of three or four exotic precious species can better demonstrate the level of greening.

Colorful leaf tree species will have a bright future.

I have always understood the concept of good seedlings in this way: adaptation, tidy crown, many roots and reasonable price. With the further deepening of urban greening, people have higher requirements for greening, and many cities will increasingly need the embellishment of colored leaf plants. Chinese people talk about spring flowers and autumn, spring is a symbol of vitality, representative color is green, autumn is the embodiment of maturity and success, need orange, yellow, red, brown and other colors. The application of rich colorful leaf tree species can better reflect the magnificence, atmosphere and simplicity of a city.

Among the colored-leaf trees, I am more optimistic about maple varieties. China is the country with the most abundant maple resources, with about 164 species. The natural and ingenious combination of maple leaf shape and leaf color, coupled with its unique Samara, make it have unique ornamental value, which has been favored by literati and landscape designers. In recent years, red-winged Acer, purple fruit Acer, camphor leaf Acer and other varieties of Aceraceae have been developed, which are mostly used for sheet planting, group planting, isolated planting and so on, in order to reflect the landscape and express the atmosphere. Its ornamental characteristics and cultural connotation have also attracted the attention of many people in the field of landscaping and urban builders.

In recent years, many companies have begun to try to introduce colored-leaf species of Aceraceae. It can be expected that the prospect of this kind of tree species will be very broad in the future.

On the other hand, I think standardized street trees and personalized tree species will be more and more favored by the market. For example, the tree posture of the golden pine is chic and unrestrained, and the autumn leaves are golden, which can better express the seasonal changes. at the same time, the tree name also caters to the Chinese people's habit of liking lip service.

Deciduous trees are in great demand.

In Wuhan, Hubei Province, people used to choose some evergreen trees as street trees, urban greening is the same, citizens are also prone to aesthetic fatigue. In recent years, people are more and more aware of the importance of using deciduous trees as street trees. Hubei has no heating supply in winter, so it can plant more deciduous trees, which can let the sun shine in in winter, which is not only conducive to daylighting, but also increase the ground temperature. From the current situation, the production of deciduous trees is far from being able to meet the market demand. In the next few years, there is still a big gap in the supply of deciduous trees, and there is also a lot of room for price increases.

Judging from the application effect in recent years, the deciduous trees suitable for planting local street trees are "tree" and "Huangshan" tree. Due to the large demand for large seedlings, the national greening market is very scarce. Some varieties such as Coral Park have good shading effect and are resistant to transplanting; Chongyang wood has vertical branches and beautiful tree shape; there are also disease-free and southern sour jujube, which are all good varieties suitable for the local area, but due to less development in the past, the quantity is less and the price is high on the market.

Among these tree species, some are not only suitable for use as street trees, but also can be planted in the courtyard, especially those with colors in different seasons, such as disease-free, coral and Aceraceae, which will be hot in the market in the future. For the undervalued varieties that are not widely used in the market, it is necessary to adopt a variety of ways to improve their added value. Such as some fast-growing tree species, should pay attention to finishing and pruning, maintenance for two or three years; for those with low survival rate of transplanting, container seedlings should be carried out.

For ordinary seedling growers, the introduction and cultivation of new varieties is a long process, and the benefits can not be seen as quickly as planting conventional tree species, and in the process of new products from cultivation to market acceptance, it takes a lot of manpower, material and financial resources, therefore, many small nurseries are unwilling to do this kind of work. Only those large nurseries with certain strength are willing to cultivate and develop new varieties. However, in fact, although the early cultivation work will cost more energy, when this kind of green seedlings is accepted by the market, these nursery enterprises can often benefit from it.
