Planting Prospect of Taxus mairei

Taxus is a plant left over from the third century, known as the "living fossil" in the plant kingdom. Because of its scarce resources, it is listed as a rare tree species in the world to be protected. Taxus is the main medicinal value of its extract-secondary metabolite derivative-paclitaxel, which was first isolated from the bark of Taxus chinensis var. mairei. Paclitaxel has high planting value. Now let's take a look at the planting prospect of yew.

Planting Prospect of Taxus mairei

The main results are as follows: 1. Taxus chinensis is a combination of medicine, timber and ornamental, and has high value of development and utilization. Paclitaxel extracted from the bark and branches of Taxus mairei is recognized as an anti-cancer drug in the world, with a price of US $500 ~ 10 million per kilogram.

2. Paclitaxel is used in the treatment of advanced breast cancer, lung cancer, ovarian cancer, head and neck cancer, soft tissue cancer and digestive tract cancer.

3. Taxus branches and leaves are used to treat leukemia, glomerulonephritis, diabetes and polycystic kidney disease.

4. Taxus mairei is lack of natural resources and drug sources, so it is being widely studied and developed all over the country.

The whole body of the yew is a treasure, so the red bean fir tree is also known as the "golden tree", and the planting prospect is promising. Where the conditions are ripe, it can be developed appropriately.

Planting value of Taxus mairei

1. Taxus has irreplaceable medicinal value: from the international market, paclitaxel products have maintained a growth rate of 20%. At present, the global trade volume of paclitaxel has been maintained at more than 1.5 billion US dollars. After entering the 21st century, the annual consumption of paclitaxel is about 1500-2500 kg, and that in the United States alone is about 300kg. While the United States can only produce about 50 kilograms; from the domestic market, although China's paclitaxel production is about 50 kilograms, only a small part of it is used for domestic patients, mainly exported to Europe, the United States and Japan. It is conservatively estimated that the demand for paclitaxel in China should be more than 1000 kg per year. The current sources of raw materials and paclitaxel pharmaceutical products are still far from meeting the needs of the domestic market. Therefore, under China's policy of expanding domestic demand, only the domestic production of taxol and the construction of yew base contain huge market prospects.

2. Greening: the root system of Taxus mairei is well developed, which can be widely used in the construction of soil and water conservation forest and water conservation forest. It is the first choice for seedlings in national key ecological construction projects.

3. Horticulture: through manual pruning, yew trees can be transformed into round, umbrella-shaped, tower-shaped and other artistic shapes, which are widely planted on both sides of roads, courtyards, parks and buildings.

4. Indoor bonsai: the unique function of Taxus chinensis var. mairei in purifying air has obvious effect on improving air quality.
