Information:
1, safflower and birch (Grevillea banksii? var？ Forsteri) is a small evergreen tree of Alpinia and Betula, a positive tree species, with a height of 7m and hairy young branches; Leaves alternate, bipinnately lobed, lobules linear, asymmetrical and smooth, with dense white hairs on the back of leaves, hence the name Betula platyphylla; Spike, terminal, brush-like, orange-red to bright red in color, like a big brush on the top of a branch, with a tubular corolla, a pistil style protruding from the corolla tube, a curved apex, and bright red flowers that are unique and gorgeous; _ _ The fruit is oval and flat, and the mature fruit is brown; The flowers are big and red, and the flowering period is long. The flowering period is from 165438+ 10 to May of the following year. The flowering period of Betula platyphylla is particularly long, lasting more than 250 days in its place of origin.
2. Honeysuckle is mainly used for the transformation of flower border, courtyard, road green belt and pine forest. Because of its fast growth, strong germination and strong adaptability, it can tolerate arid and barren soil, is suitable for well-drained and slightly acidic soil and is suitable for transplanting in spring. In order to increase the flowering of birch, it should be pruned once a year. In the flower border, Betula platyphylla can be used as the upper tree species for background planting, and other shrubs and ground cover roads can also be used as isolated tree species; In parks and gardens, it can be planted as an ornamental tree alone or in groups. Birch has a long flowering period, beautiful appearance and good anti-pollution ability. Once introduced, it has been favored by the landscaping market.
3. Betula platyphylla, also known as Betsy Betula, originated from the coast of Queensland, Australia and nearby islands, and is now introduced and cultivated in Xishuangbanna; It is a shrub with dense flowers and leaves, changeable plant shape, slender branches and elegant crown. When the flowers bloom, the trees are full of flowers, all dazzling red.
4. The Betula platyphylla introduced and cultivated by Xishuangbanna Tropical Botanical Garden Economic Plant Experimental Extension Station of China Academy of Sciences in 2009 grew well without obvious diseases and insect pests. Now it has blossomed and borne fruit, and is widely used in landscaping.
Value:
1 is very suitable as an ornamental plant. There are many reasons, such as long flowering period, beautiful appearance and good anti-pollution ability, so it is very popular in gardens. In addition, it can also be planted on both sides of roads in parks and residential areas. Every time it blooms, the trees are full of red, which is very dazzling and pleasing to the eye, and can make passers-by shine at the moment. Of course, it can also be planted as a background tree species, and it can also be planted with other kinds of trees as isolation belts. In addition to outdoor planting, indoor potted plants are naturally very good and can bring vitality to the room. In a word, its value is the most important.
2. There have been experiments in forestry, and the results show that this plant has stronger absorption capacity of SO2 and various chlorides than many woody plants, and the specific content can even be found in the literature. The other is to reduce noise, improve local climate, improve soil quality and so on. Many plants have this effect, so I won't say much here.
Because this kind of plant is very suitable for greening construction, the market is relatively broad. Previously, due to the low domestic seed production and relatively high import price, it was limited to its extensive cultivation. But it's different now. With the development of science and technology, the problems of its propagation and cultivation have been basically solved, and mass planting has become possible.
