Abstract:

Reasonable fertilization is an important measure for high yield of Camellia oleifera with good quality. Fertilization can enhance photosynthesis rate, water using efficiency and stomatal conductance, so that growth and yield of C. oleifera are promoted. Prescription fertilization significantly improves vegetative growth of young C. oleifera trees. Tree growth, foliar P concentrations, N mineralization rate, nutrient supply and microbial activity may be improved after addition of N + P fertilizer. Fertilizer species of C. oleifera includes base fertilizer and top dressing, which are fertilized by furrow application and leaf spraying, and spring and early summer are effect fertilization seasons. Future research of C. oleifera fertilization will focus on developing a simple and practical fertilizer response function, applying management information system supported with 3S technology on C. oleifera fertilization, research and production of C. oleifera -specific fertilizer and slow/controlled released fertilizer.
