Techniques for Container Seedling Cultivation of Torreya grandis ‘Xifei’

Experiments were conducted on container seedling cultivation of Torreya grandis ‘Xifei’ in Songyang of Zhejiang province with different substrates, different containers and different quantity of slow release of fertilizer. 1-year seedlings were T. grandis ‘Xifei’ as scion grafted on 2-year T. grandis as stock. One year later, determinations demonstrated that survival rate of seedlings in non-woven bag was 36% higher than that in plastic cup. New shoot growth of seedlings was influenced by moisture content of soil>substrate>slow release fertilizer. Ground diameter increment of seedlings was significantly affected by moisture content of soil>slow release fertilizer>substrate. Comprehensive evaluation on seedling quality resulted that the best substrate was sub top soil: waste mushroom stick: peat = 2: 1: 1, with non-woven bag as container, and 30g slow release fertilizer each seedling.
