Based on forestry production practice, this paper reviewed the biological and ecological characteristics, cultivation techniques, and comprehensive utilization value of Castanopsis hystrix. The current-year branches of C. hystrix are purplish brown and the biennial branches are dark brown to black; the leaves are papery or thinly leathery and lanceolate, and the nuts are broadly conical and glabrous. This tree mostly grows in hilly areas and mountain foothills, and prefers humid tropical and subtropical monsoon climates. In terms of cultivation techniques, seeds certified or recognized as forest improved varieties should be selected, and shriveled and worm-eaten seeds should be eliminated by flotation. The selected seeds are subjected to surface sterilization and insecticidal treatment with 2% potassium permanganate solution and other agents, followed by sand storage treatment. Seedbeds with acidic soil, a height of about 20 cm and a width of about 90 cm should be selected, after which the seedbed surface is leveled (with a loose soil layer of about 15 cm maintained). The seeds are subjected to constant temperature wet sand stratification for 60 to 80 days to promote germination. Seedling propagation can be realized by sowing, cutting, grafting, tissue culture rapid propagation and other methods, and it is necessary to strengthen shading, sun protection, water and fertilizer management at the seedling stage. For stand cultivation, site conditions with acidic red soil, yellow soil or latosol red soil are preferred; site clearing should be completed 2 to 3 months before afforestation, with strip or hole soil preparation adopted. Afforestation is conducted in February to March with healthy afforestation seedlings of more than 1.5 years old that have well-developed root systems, vigorous growth, no diseases and pests and no tree body damage. Planting patterns such as C. hystrix pure stands and C. hystrix coniferous-broadleaved mixed stands can be adopted, and tending management measures such as weeding and thinning should be well implemented. Sprout thinning is carried out when the sprouts grow to about 1 m in height after felling. The common diseases and pests of C. hystrix include leaf blight, root rot, leaf rollers, cockchafer and so on, which can be controlled by integrated measures such as agricultural, physical, biological and chemical control. In addition, this tree possesses value in wood processing, fruit development and utilization as well as the ecological functional value in mixed forest establishment, with great potential for comprehensive utilization. This paper provides a reference for the cultivation and utilization of C. hystrix.
