But because the yew is toxic, the clinical dosage is very small, usually 6-8 grams, no more than 10 grams, otherwise it is easy to be poisoned, such as dizziness, pupil dilation, nausea, vomiting, muscle weakness and other symptoms, serious cases can even lead to death.

Culture methods of Taxus mairei

1. Soil: the soil of Taxus chinensis culture should be loose, rich in humus, water, fertilizer and breathable soil, and the mixed matrix composed of peat soil, perlite and loam can be selected, but it is not suitable to be used because of the impermeability of clay, poor fertilizer retention and poor water retention of sand.

2, illumination: the yew sex likes the shady growth environment, the cultivation process should be shaded properly, should not be placed in the place with direct sunlight, that will make the water of the yew evaporate quickly, cause the branches and leaves to be dehydrated and the leaves dry up. In the middle of summer, the yew can be placed in the living room, balcony, corner and other places during the day, and then put on the windowsill to breathe in the evening. At the same time, the lack of light will also affect the growth of yew, so in the climate where the sun is not strong, it should be properly exposed to sunlight.

3. Fertilization: Taxus culture should fertilize the soil in time. It is better to apply 0.2 jin of organic fertilizer and 0.02 jin of compound fertilizer per plant, and it can also increase the application of farm fertilizer and cake fertilizer (such as cottonseed cake, peanut cake, hemp cake) and so on. Fertilizer should be sprayed along the basin wall as far as possible, not close to the root of Taxus mairei. In general, the newly bought yew bonsai has its own nutritious soil, which does not need to be fertilized in the first 3 months, but can be applied in 2-3 months.

4. Watering: if the leaf surface of the yew is tired, it should be watered. If the leaf surface is sagging, it indicates that the water shortage is serious. In addition, the need for watering can be judged by knocking on the basin to listen to the sound. If the sound is empty when knocking on the basin, it means that the soil is dry and it is time to water. Insert your finger into the soil 2cm to 3cm. If the soil feels dry, it also needs watering. Generally, the yew placed outdoors is watered every 15-20 days and indoors every 20-25 days. It is best to keep the moisture content of the soil about 40%.

5. Trimming: when the lower branches of the yew bonsai grow too dense and the dry yellow leaves fall off, part of the overdense branches can be cut off and can be cut into umbrella type, tower type, round shape and so on. When changing the basin of the yew, if the root can not keep up with the nutrient supply of the root and branches and leaves, and the leaves curl and dry, we can reduce the nutrient consumption of branches and leaves and restore the root growth quickly through pruning.

6. Change the basin: after about a year of yew cultivation, the seedlings will gradually grow up, and the root system will also develop, so it needs to be transplanted and changed. When changing the basin, you can break the old basin, but do not damage the original soil ball, move it into the new basin, watering and rooting in time, so that the root system of Taxus mairei is closely combined with the soil.

7. Diseases and insect pests: under normal conditions, there are very few insect pests in yew culture. if yew is found to be withered and yellow or diseases and insect pests are found, it can be irrigated or sprayed with methyl topiramate and potassium dihydrogen phosphate. Relatively speaking, the yew will occur root rot, stem rot and root rot during the rainy season, especially young trees. In high temperature and dry season, Taxus is prone to leaf blight and red blight, which can be controlled by spraying Bordeaux solution.

8. Note: the yew does not have great requirements for the growth environment, the main thing is that it cannot be exposed to direct sunlight, cannot be blown to the air conditioner in summer, cannot be close to the heating in winter, and cannot throw cigarette butts, tea and other sundries into the breeding pot at will, which will adversely affect the growth of the yew. The flowerpot of breeding yew should choose a slightly larger one, and a few more holes can be made in the lower part of the pot to enhance the water permeability and air permeability of the flowerpot.
