Characteristics of 1-year-old Taxus wallichiana var. mairei (southern Chinese yew) seedlings and key points of seedling-stage management
For container seedling raising of Taxus wallichiana var. mairei (southern Chinese yew), a container size of 8cm×12cm is appropriate. After sowing, the soil temperature should be in the range of 18-25°C; after about 25d the seeds can break through the soil and germinate, with uniform germination and a high germination rate. If the temperature is below the lower limit, the seeds are difficult to germinate, and the germination rate is low and uneven. After the seeds germinate, from early June to early October, shading with a shade net of about 50% light transmittance is required. The seedlings have strict requirements for water and fertilizer; in the middle and late growth stages, more phosphorus fertilizer should be applied to promote the increase of ground diameter, root system and biomass.
