When does the yew flower bloom and the planting prospects are large?
When does yew bloom? Is the planting prospects large? The yew is called the living fossil in the plant kingdom. Because of its scarce resources, it is listed as a rare tree species in the world. The medicinal value of yew is mainly its extract. The metabolic derivative, paclitaxel, paclitaxel was originally an anti-tumor active ingredient isolated from the bark of Taxus chinensis. It has high planting value. In general, the prospect of planting yew is still very good!
Planting prospects of yew
- The yew is a combination of medicinal, medicinal, and ornamental. It has a high development and utilization value. Paclitaxel extracted from the bark and branches of yew is recognized as an anticancer drug in the world, and the price is 5-10 million per kilogram. Dollar.
- Paclitaxel is used to treat advanced breast cancer, lung cancer, ovarian cancer, and head and neck cancer, soft tissue cancer, and digestive tract cancer.
- Taxus leaves are used to treat leukemia, nephritis, diabetes, and polycystic kidney disease.
- The natural resources of yew are scarce and the source of medicine is scarce. Therefore, all localities are conducting extensive research and development.
The whole body of the yew is a treasure, so the yew tree is also known as the "golden tree", and the planting prospects are promising. Proper conditions can be developed.
Planting value of yew
Taxus has an irreplaceable medicinal value: from the international market, paclitaxel products have maintained a growth rate of 20%. The current global trade in paclitaxel has remained above $1.5 billion.
After entering the 21st century, it will consume about 1,500-2,500 kilograms of paclitaxel per year, and only about 300 kilograms will be consumed in the United States alone. The United States can only produce about 50 kilograms; from the domestic market, although the production of paclitaxel in China is about 50 kilograms, only a small part is used for domestic patients, mainly exported to Europe, the United States and Japan.
The demand for paclitaxel in China is conservatively estimated to be more than 1,000 kg per year. The current source of raw materials and paclitaxel pharmaceutical products are far from meeting the needs of the domestic market. Therefore, under China's policy of expanding domestic demand, only the domestic production of paclitaxel and the construction of the yew base have huge market prospects.
Greening: The root system of yew is very developed. It can be widely used to build water and soil protection forests and water conservation forests. It is the first choice for national key ecological construction projects.
Horticulture: The yew tree shape can be turned into a round shape, an umbrella shape, a tower shape and the like by artificial pruning. It is widely planted on both sides of the road, in the courtyard, in the park and around the building.
Indoor bonsai: The unique function of the yew to purify the air has a significant effect on improving air quality.

The yew can't distinguish between male and female before the result, and there will be a change between male and female due to changes in environment and climate. After long-term cultivation and maintenance experience, the proportion of female trees is far greater than that of male trees.
The results of the Taxus chinensis var. chinensis are the female and male plants of the genus Taxus. The ratio of female to male is 9:1. The female plants are planted after 4-5 years, and the flowering results can be carried out. The flowering period is 4-5 months. Period from June to November. The fruit is born on the mother branch of the previous year, and the number of female branches is ensured when the female is pruned, so that the yew results in the next year.
