The reason why Taxus chinensis has been well-known and cultivated in every household before is that Taxus chinensis is not only excellent wood, but also contains an anticancer substance called "paclitaxel", which is recognized as an anticancer medicine in the world. It has extremely high medical value. Plus the tall yew is endangered. Therefore, its small seedlings are scarce, and almost every household plants a few. Why are there so few races of Taxus chinensis now? The main reasons are as follows: first, it grows very slowly and takes many years to grow to a usable size. Obviously, no one wants to do such a project with too long investment time.
Secondly, Taxus is a shallow-rooted plant, and its taproot is very weak, which also leads to its poor nutrient absorption capacity. If it does not grow in very fertile soil under natural conditions, it will be difficult to grow into wood, which is one of the main reasons why it has lived on the earth for 2.5 million years and eventually became an endangered plant.
In addition, Taxus chinensis has high requirements on soil properties, because it grows well in acidic soil, but not well in neutral soil, and cannot grow normally in alkaline soil. In addition, Taxus chinensis has strict requirements on light and must grow in an environment with astigmatism and brightness. The maintenance environment with too dark and too strong light will affect its normal growth. It is really difficult to plant such a delicate "little pimple" on a large scale.
In addition, the resistance of Taxus chinensis is not strong, and it is particularly prone to root rot in the growth process. At the same time, its regeneration ability is very poor. Once root rot occurs, it is difficult to repair itself. Even after root cutting, disinfection and replanting, it is difficult to survive. To sum up, there are many reasons why the highly publicized and valuable yew has not developed, but fewer and fewer people are planting it.
