摘要:

【Objective】This research studied the effects of different fertilizer proportions on camellia seedling growth and nutrient absorption in order to provide reference for the development of special camellia seedlings foliar fertilizer. 【Method】Using nutritional-cup grafted camellia seedlings as research subject, under orthogonal test, 9 different foliar fertilizer concentration treatments with various NPK ratios application and the water control treatment were spayed onto camellia leaves during the seedling stage to determine the seedling growth indexes and the nutrient element contents in camellia roots, stems, and leaves. 【Result】The best NPK fertilizer ratio for the promotional growth of camellia seedlings was 11-13-4, and the optimal treatment spaying concentration was at 2%, which reached significant difference compared with other treatments. After foliage fertilizer application, the N, P, and K nutrition contents in stems and leaves greatly improved; the nutrient requirements of camellia seedlings were arranged in the order of N>K>P. By spraying foliar fertili-
zer, the requirements for trace elements were effectively complemented in camellia seedlings. 【Conclusion】Suitable NPK composition and foliar fertilizer spraying concentrations could promote the growth of camellia seedlings and enhance plant nutrient absorption and usage efficiency.
