It is a precious tree species that has both ornamental and medicinal uses. So,? How to breed yew
1. Light: Yew likes a cool growth environment, so during the breeding process, it should be properly shaded and should not be placed in a place with direct sunlight, which will cause The water in the yew evaporates rapidly, causing the branches and leaves to become dehydrated and the leaves to wither. In midsummer, yew trees can be placed in the living room, balcony, corners, etc. during the day, and then placed on the windowsill for ventilation in the evening. At the same time, lack of light will also affect the growth of yew, so in climates where the sun is not strong, it should be properly exposed to sunlight.
2. Watering: Normal yew leaves are tall and bright. If you find that the leaves appear tired, you should water them. If the leaves are drooping, it indicates a serious lack of water. In addition, you can also judge whether watering is needed by tapping the pot and listening to the sound. If the sound is hollow when tapping the pot, it means that the soil is dry and it is time to water. Insert your fingers 2-3 cm into the soil. If the soil feels dry, it needs watering. Generally, yew placed outdoors should be watered once every 15-20 days, and indoors should be watered once every 20-25 days. It is best to keep the soil moisture content at about 40%.
In different periods, plants need different amounts of water. During the growth period from March to November, they need more water, and during the dormant period from December to February, plants need more water. Requires less moisture than. In spring and autumn, it is generally watered once every 5 to 7 days, in summer it is watered once every 3-5 days, and in winter it is watered once every 7 to 10 days, that is, it is watered enough at one time. However, it should be noted that yew should not be watered with tea water. Watering too much and too frequently will cause root rot of yew.
3. Soil: Yew cultivation should use soil that is loose, rich in humus, water-retaining, fertilizer-retaining, and breathable. A mixed matrix of peat soil, perlite, etc. and loam can be used. Since clay is not breathable and sandy soil has poor fertilizer and water retention properties, it is not suitable to use it. In addition, yew cultivation should fertilize the soil in time. It is better to apply 0.2 catties of organic fertilizer and 0.02 catties of compound fertilizer per plant at a time. Farmyard manure and cake fertilizers such as cottonseed cake, peanut cake, hemp cake, etc. can also be applied. When applying fertilizer, try to spread it along the pot wall and not close to the roots of the yew. Generally, newly purchased yew bonsais have their own nutritious soil and do not need to be fertilized within the first 3 months. Fertilizer can be applied after 2 or 3 months.
4. Pest and disease control: Under normal circumstances, there are very few pests in yew farming. If the yew is found to be withered or damaged by diseases and insect pests, you can water or spray it with thiophanate methyl and potassium dihydrogen phosphate. Relatively speaking, yew will suffer from root rot, stem rot and root rot during the rainy season, especially for saplings. At this time, dika pine can be sprayed for maintenance. During high temperature and drought seasons, yew is prone to leaf blight and red blight, which can be controlled by spraying Bordeaux mixture.
5. Precautions for growth environment: Yew does not have many requirements for the growth environment. The main thing is that it cannot be exposed to direct sunlight, cannot be exposed to air conditioners in summer, cannot be near heaters in winter, and cannot be careless. Throwing cigarette butts, tea leaves and other debris into the breeding pot will have a negative impact on the growth of yew. The flower pot for cultivating yew should be slightly larger, and a few more holes can be drilled in the lower part of the pot to enhance the water permeability and air permeability of the flower pot.
6. Bonsai trimming: When the lower branches of the yew bonsai grow too densely and dry yellow leaves fall off, part of the lower branches that are too dense can be trimmed into umbrella or tower shapes. shaped, round and other shapes. When repotting the yew, if the root system cannot keep up with the nutrient supply to the roots and branches and leaves, and the leaves become curled and dry, you can reduce the consumption of nutrients by the branches and leaves through pruning and quickly restore the root growth.
7. Transplantation and repotting of yew: After about one year of cultivating a new yew, the saplings will gradually grow and their root system will develop accordingly. Therefore, transplantation and repotting are required.
When changing pots, you can smash the old pot, but do not damage the original soil ball. After moving it into the new pot, water it in time to fix the roots so that the yew root system and the soil can be closely combined. The value of landscaping
Landscaping in front of and behind the house, on empty slopes, and on both sides of the road is also suitable for planting. Once planted, it will benefit for many years and the benefits will be significant.

In Asia, China, Myanmar, Indonesia and other countries have more wild yew trees.
Taxol extract TAXOL PACLI TAXEL has a unique anti-cancer mechanism. Dr. BRODER, director of the National Cancer Institute of the United States, said that after doxorubicin and cisplatin, paclitaxel has been considered the most effective anti-cancer drug in the past fifteen years. New anti-cancer drugs that are effective against many types of cancer and have few side effects. Since the 1980s, the United States, the United Kingdom, Russia, South Korea, and China have all carried out in-depth research. The United States took the lead in applying research results to clinical medicine and achieved remarkable clinical results in the treatment of various cancers. Since then, humans have made new breakthroughs in the field of anti-cancer. Therefore, so far and even for a long time to come, the most useful weapon for humans to fight cancer can only be paclitaxel.
Paclitaxel is mainly extracted from the roots, bark, stems and leaves of the yew tree. Due to the complexity of the extraction process, the difficulty in removing the chlorophyll component from the original solution, the large investment in equipment, and the lack of sources of raw materials, the regular extraction of paclitaxel developed relatively late in our country. In the 20th century The nineties had just begun. Feng shui placement of yew
