Taxus chinensis can be pruned during growth and dormancy. Pruning in growth period is mostly from April to 65438+10 month, and pruning in dormancy period is from 165438+ 10 month to March of the following year. In spring, it is necessary to remove the core and accelerate germination, promote the development of lateral branches and control the branch density. Appropriate thinning is needed in summer to cut off dense branches and cross branches. In autumn, you need to cut it short and cut the branches neatly. In winter, you should pull the branches and shape them. I. Pruning time Taxus chinensis pruning can be divided into growth pruning and dormancy pruning, in which the growth pruning is carried out from April to 65438+10 every year and the dormancy pruning is from 165438+ 10 to March of the following year. Growing plants recover quickly, so they are suitable for shaping by pruning. Dormancy pruning is mainly to prepare for the next year's growth. Second, pruning method 1, core removal: Pruning yew in spring, mainly core removal and bud smearing. In order to prevent plants from growing too high and promote the development of lateral branches, the terminal buds of branches should be cut off. If it has too many buds, it can grow many new branches, but if the nutrition is insufficient, some of them will weaken and can be eliminated in advance by wiping buds. 2. Thinning: Thinning of yew in summer is mainly used, because the temperature is high in summer, the plants will grow exceptionally luxuriantly. If it is not sparse, it will affect the internal ventilation and light transmission, and may also cause pests and diseases. Therefore, it is necessary to cut off dense branches, cross branches and overlapping branches to provide space for the growth of new branches. 3, cut short: in autumn, it is much easier to trim the yew. In addition to cutting too long branches short, just cut off some dead branches and diseased branches. If you want a better shape, you can also cut it neatly. 4. Branching: Generally, the branches of potted yew will grow very densely and it is not easy to have a tree shape. If you want to turn it into a bonsai, you must pull branches in winter. Pull branches in different directions with ropes. As time goes on, it will grow like a crown and look more ornamental.
Taxus. ): All plants are evergreen trees or shrubs, dioecious and cross-pollinated. Cones are small, solitary in leaf axils and open in early spring. Male cones are heads with stalks and scales at the base, stamens 6- 14, peltate, and each stamen has 4-9 anthers; The female cone has a terminal ovule, a discoid receptacle at the base and several bracts at the lower part.
Seeds nutlike, spherical, inserted in red fleshy cup-shaped aril, mature in that year. There are about 1 1 species in this genus, with evergreen leaves, dark green leaves and red aril, which are quite beautiful. It is an excellent ornamental shrub and can be used as a landscape tree species in gardens.
And it is often used in Christmas garlands. The sapwood of this genus is narrow, which is obviously different from heartwood. It has no resin channels and resin cells, uniform texture, fine structure, high hardness, strong corrosion resistance and strong toughness. It is an excellent material for buildings, bridges, furniture and equipment. Taxanes are only found in this genus in the world, so they can be used to synthesize anticancer drug paclitaxel. Distributed in temperate to tropical regions of the northern hemisphere.
