Taxus mairei is a national first-class key protected wild plant, also known as Taxus mairei, Taxus mairei, etc., it is an evergreen tree of Taxus mairei, distributed in the provinces south of the Yangtze River Basin, Henan and Shaanxi. Although the distribution area in Guizhou Province is wide, but the population is rare, if it is not protected, it is in danger of being in danger.

Note: Taxus mairei is mainly produced in the south of the Yangtze River Basin in China. Guiyang City is mainly distributed in Huaxi, Wudang, Kaiyang, Xifeng and other places. Anhui Province is mainly distributed in Shimen Township and Huangshan District, Shexian County, Huangshan City. Baishanzu National Reserve in Zhejiang Province is also widely distributed, among which Sandui Village to Jingning in Qingyuan Scenic Village is the most.

Propagation methods of Taxus mairei

1. Sowing: Taxus chinensis var. mairei is generally sown in early spring. After 1 year of seed storage, 30% of the seeds are white, sift out the seeds in time, disinfect them in 0.2% potassium permanganate solution for 10 minutes, rinse them with clean water and sow them evenly in the ditch after drying the water. After sowing, the yellow loam soil with mycorrhiza and sifted under the pine forest was dug to cover the seeds, and the thickness was no seed. Pay attention to shading in the seedling stage, build a shade shed in the seedling stage, and the seed emergence rate is more than 70%.

2. Cutting: in the period of dormancy and germination of trees, the mixed substrate of sand, sawdust and perlite was selected as cutting soil. Select 1 ~ 4-year-old lignified branches and cut the cuttings into small segments 10 cm, 15 cm or 30 cm long. when pruning, the cut should be smooth, lower cut Malt-shaped, and the leaves should be removed below 2 cm. After cuttings were treated with chemicals such as ATP, ABT, NAA, IBAA and so on, the cuttage survival rate was generally more than 85%.

Cultivation techniques of Taxus mairei

1. Site selection: the cultivation of Taxus mairei should choose loose, humus-rich, neutral or slightly acidic alpine platform, deep moist brown soil and dark brown soil on both sides of valleys and streams. Deep turning, leveling, according to the row spacing of 0.4 × 1.0 meters or 0.4 × 0.4 meters to open holes, hole depth of 40 cm, ready for planting.

2. Soil preparation: generally, it is better to raise seedlings and transplant under the pine forest according to local conditions, and choose slash pine or Masson pine forest land with canopy density of 0.6-0.7 and no diseases and insect pests as nursery land, which requires gentle slope, deep upper layer and good drainage. The weeds and shrubs in the forest were removed from August to September and arranged into horizontal ladders, dug 20cm to 30cm deep, and raked shallowly in November.

3. Fertilization: when Taxus chinensis var. mairei was cultivated, the mature basal fertilizer was applied to 40% 60 piculs / mu (1 mu 2 / 15 ha), the bed was made into separate beds, the bed was 15 cm high and 1.2 meters wide, and the sowing ditch was pressed out with a wood board 15 cm wide, with a depth of 2 cm and a distance of 20 cm.

4. Transplanting: general seed seedling for 1-2 years, cuttage propagation for about 1 year, when the seedling height grows to 30-50 cm, it can be transplanted. Transplanting was carried out before sprouting in October-November or February-March. One seedling was planted in each hole and watered to cover the sprout properly.

5. Management: after seed emergence, weeds should be often pulled out, topdressing once or twice a year, and preventing stagnant water in rainy season to prevent rotting roots. After setting sandalwood, it is ploughed and weeded twice a year, and after the woodland is closed, it is generally only ploughed and weeded in winter and cultivated for 5 times. Combined with mid-tillage and weeding for topdressing, the main source of fertilizer is farm manure, and the sprouting should be cut off in the young tree stage to ensure that the trunk is straight and fast-growing.
