Yew, also known as yew tree and Guanyin fir, is an evergreen tree or shrub of the genus Taxus in the family Taxaceae, dioecious and cross-pollinated. It is an ancient tree species that has been on Earth for 2.5 million years. It originated in the Early Cretaceous and began to diverge in North America during the Late Oligocene to Early Miocene, before reaching Asia via the Bering land bridge. Yew gets its name from its fruit, which is bright red when ripe, hence its name. In ancient poetry, yew is often used to symbolize love and longing, such as the Tang Dynasty poet Wang Wei's "Acacia" red beans are born in the south, and a few branches are sent in spring. Yew is mentioned in .
In China, yew is widely distributed, especially in Mingxi County, Sanming City, Fujian Province, where the distribution of yew is relatively rich and concentrated. In addition, yew is also a widely recognized "living fossil of plants", and it is also a natural rare anti-cancer plant. However, it is worth noting that the survival of yew has been seriously threatened in recent years. Due to overexploitation, the wild resources of this genus in Eurasia have declined dramatically, and the population has even become extinct in some areas. In order to protect this rare species, China's state forestry authorities, under the appeal of experts in relevant disciplines and local authorities, urgently formulated administrative regulations, cooperated with the relevant national laws and regulations, and began to launch a huge emergency stop action against the illegal activities of indiscriminate logging of yew trees that are occurring in various places.
Yew trees are up to 30 meters tall and have a diameter at breast height of 60-100 cm;The bark is grayish-brown, reddish-brown or dark brown, split into strips and shed;Large branches develop, annual branches green or light yellow-green, autumn to greenish yellow or light reddish-brown, two- and three-year branches yellow-brown, light reddish-brown or gray-brown;Winter buds are yellowish-brown, light brown or reddish-brown, shiny, the buds are triangular-ovate, and the back is ridgeless or longitudinally ridged. It is a plant with a unique charm and ecological value, which is loved by gardening enthusiasts and botanists. Understanding the habits of yew is the key to maintaining it. This article will explain the living habits of yew in detail to help you better understand and maintain it.
1. The growth environment of yew.
Yew prefers a cool, moist environment and is hardy and can withstand temperatures as low as -25. Under natural conditions, yew grows slowly and has poor regeneration ability, so for a long time, there has been no large-scale yew raw material forest base in the world.
2. Growth and development characteristics of yew taxus.
Growth rate: Yew grows at a slower rate and requires patience and careful care.
Propagation method: Yew is propagated mainly by seeds, but it can also be propagated by cuttings.
Growth stage: The growth stage of yew is divided into seedling stage, growth stage and maturity stage. Each stage has different maintenance needs.
3. Maintenance skills of yew.
1.Soil management: Yew is very demanding on the land on which it is grown. Its roots are not obvious to a certain extent, and due to the underdeveloped nature of its root system, it will greatly reduce the absorption of water and nutrients. This requires us to provide sufficient water and fertilizer at the time of planting. And when planting, we must choose the soil is relatively loose, the land is rich in a lot of nutrients, and the nutrients in the land contain various humus. At the same time, it is also necessary to pay special attention to the fact that yew prefers weakly acidic soil, which requires us to do a good job of testing when choosing land, and if we cannot find suitable land for the lack of it, we can take appropriate measures to adjust the pH value of the land to meet the requirements.
2.Light management: Yew prefers to absorb sunlight, so be sure to choose a good light area for cultivation when planting to ensure that it has enough light. There are many enthusiasts who prefer to cultivate yew indoors, and this practice eventually leads to the demise of yew trees. This is because the environment with low light intensity is extremely resistant to the growth of yew trees.
3.Growing environment: Yew is drought tolerant and resistant to cold. The suitable average annual temperature is 2 degrees to 7 degrees, the annual precipitation is 750 mm to 1000 mm, and the pH value of the soil is 55-7。
4.Seed propagation: After harvesting from September to October, the red fruit is rubbed by hand to remove the false skin and pulp, washed with water, and then removed and mixed with wet sand and stored in outdoor soil. At the end of March and the beginning of April, after the stored seeds are taken out, they are germinated indoors, and then sown, and the seedlings can emerge in 20 days after sowing.
5.Propagation by cuttings: From May to June, cut the young shoots of the current year from the mother tree that has grown for more than 4 years as cuttings, and the length of the cuttings needs to be 15 cm. Remove the leaves from the underside of the cuttings and peel off the base by 0For a 5 cm to 1 cm annular wound, after the nodules form around the wound, cut off the lower part of the annular wound, and then soak the base of the branch in 100ppm suctioned acetic acid or phenylacetic acid for 3 hours.
Fourth, the culture and value of yew.
History and culture: Yew has a long history and cultural background in China, and is regarded as a symbol of auspiciousness and longevity.
Medicinal value: The bark and leaves of yew have medicinal properties and can be used for some diseases.
Ornamental value: Yew trees have beautiful shapes and green leaves, which have high ornamental value.
Ecological value: Yew is an evergreen tree species that can maintain water and soil, purify the air, and have a positive effect on the ecological environment.
Through the above detailed analysis of the living habits of yew, I believe you have a deeper understanding of yew. Understanding its habits is the key to taking care of it, and only by mastering this knowledge will you be able to provide the right environment for yew to thrive in your home. At the same time, understanding the culture and value of yew can also make you cherish and care for this amazing plant even more.
