Abstract: Fertilization is one of important measures to promote the plant growth.In this paper,according to three different fertilizer types and different ratios of N,P and K,with 9 treatments and a comparison group,and by adopting the LSD multiple comparion research method on three-year-old Camellia oleifera and ten-year-old Camellia oleifera,analysis was made of different formula fertilization effects on young Camellia oleifera growth and adult Camellia oleifera fruit yield.The results showed that the different formula fertilization could stimulate the growth of young C oleifera and fruit yield of adult C oleifera.The four treatments (6,7,8 and 9) had the biggest influence on diameter and height among 9 treatments;The three treatments (7,8 and 9) had the biggest influence on fruit yield of adult C oleifera.
