The rare tree species Fraxinus hupehensis is the only rare tree species in the world today, with a life span of about 2000 years. Due to its slow growth, ash is a rare and endangered plant under national key protection. There is also a folk story about the white wax in the festival, saying that it was chopped into knots because it was "not satisfied" with Wu Zetian.
Fraxinus ash is a deciduous tree, with beautiful shape, delicate quality, intertwined, ancient and beautiful. Its leaves are small and beautiful, green, dense and vertically symmetrical, resistant to picking and pruning, and excellent in shape. Shao Huosheng, general manager of Wuhan Optics Valley Horticultural Engineering Co., Ltd. commented that Fraxinus chinensis is a veritable rare tree species with cultural connotation, scarcity and high ornamental value.
In the past, Fraxinus mandshurica was mainly used as bonsai material. In recent years, with the application of precious landscape trees such as Podocarpus in landscaping, some nurseries in Hubei have also pruned the collected Fraxinus mandshurica trees to cultivate high-grade modeling seedlings. Shao Huosheng said that after careful pruning and modeling, the Grifola frondosa in the street is either strong and determined, flat and broad, or elegant and swaying. It is leafy in summer and autumn, vigorous and simple in winter, and proud in character. It can be called "three-dimensional painting, poetry without words". But because people don't know enough about it, the current market price is only one-fifth to one-tenth of the same specification.
Landscape modeling trees with strong resistance can be used for greening important nodes such as urban green space, parks and courtyards. , and can be used to improve the landscape effect. In practical application, it can be planted individually or in groups. Using landscape stones and some small shrubs to plant trees alone can achieve the effect of one tree, one stone and one scene. "When three or five trees are planted in combination, they should be placed in a patchwork manner, and then the terrain should be well done, and then a landscape map will naturally be formed with landscape stones and flowering shrubs." Shao Huosheng said.
In application, Fraxinus mandshurica has the outstanding advantages of strong resistance and easy management. The origin of ash tree is the transitional zone between north and south climate. It was found that there was no adverse reaction at the lowest temperature of -20.3℃ and the highest temperature of 42.3℃. At present, it has been applied in batches in Jinan, Qingdao, Weifang, Beijing, Tianjin and other northern regions. It can survive the winter smoothly under the microclimate conditions in Shenyang.
Fraxinus ash has strong vitality, vigorous germination, light-loving, slightly shade-tolerant, and can be divided into roots, cuttings, sowing and propagation, with simple management. Smoke and dust resistance, no pollution, drought and flood resistance, barren resistance, lax requirements on soil, no pests and diseases. Whether it is raising roots and exposing claws or flooding fertilization, it is adapted to growth.
In the south of China, Fraxinus mandshurica can survive the winter without any cold-proof measures, and in the particularly cold north, measures such as winding straw ropes, building windbreak walls and spraying antifreeze can be taken to properly prevent the cold.
Pruning resistance, easy shaping, strong germination, high incidence of side branches, suitable for heavy cutting and light cutting, quick setting and beautiful shape. Roots, stems and branches can be cut, trimmed, climbed and carved. The following are the tips for making ash bonsai carefully arranged by Senbao.
1. Tips for getting started with embryo selection
Firstly, it is necessary to judge whether the selected ash pile head can survive after transplantation, and secondly, it is necessary to judge whether the selected ash pile head has modeling prospects.
2. The key to getting started is to break the embryo
That is, changing trees. The bonsai selected from the blank has different shapes, lush foliage and disorder. It is necessary to determine which bonsai tree type is suitable according to the head, root, stem and branch of ash bonsai. Observe the bonsai carefully from all angles, and choose the observation surface of the bonsai that will remain gray in the future; Finally, the position of the bracket should be designed. Only by combining the three factors and transforming bonsai into embryos can we have a solid foundation and make bonsai useful.
3. The key to entry.
Before planting ash bonsai, the wound should be disinfected and sealed. The initial planting can be done in situ or in potted plants. Ground planting is beneficial to root growth, bonsai grows quickly and the timber production cycle is short; Potting is easy to control the shape of the root system. The daily management of ash bonsai after planting is very important, and it is necessary to ensure the temperature, humidity, sunshine and moisture of the environment; Rational fertilization should be carried out.
4. Getting started with the key cultivation.
After the initial planting, ash bonsai began to take root and sprout, and gradually flourished. At this time, we should not rush for success, but let it "grow wildly" and promote the development of its root system. When entering the breeding season, according to the proposed composition, gradually and repeatedly cut off branches, trim useless branches, bend branches along the corners, and hold up the shape. After a long period of training and careful maintenance, your work can be successful.
