The invention belongs to the field of foliar fertilizer, and relates to a special multifunctional foliar fertilizer for oil-tea trees. The special multifunctional foliar fertilizer for oil-tea trees comprises the following ingredients in parts by weight: 5-10 parts of urea, 5-8 parts of potassium dihydrogen phosphate, 3-4 parts of boric acid, 3-4 parts of magnesium chloride, 5-6 parts of calcium nitrate, 4-5 parts of glucose, 0.1-0.5 part of gibberellin, 0.5-1 part of abscisic acid, 3-5 parts of amino acid chelate, and 2-3 parts of surfactant. According to the foliage fertilization principle and aiming at the characteristics that the wax and cuticle on oil tea leaves are thick and the demand on nutrients is large and by utilizing and reasonably proportioning the main active ingredients of mineral elements, hormones, amino acid chelate, surfactant and the like, the foliar fertilizer can be effectively absorbed by the oil tea trees, and has multiple effects of promoting the seedling survival, improving the growth and fruit bearing and cultivation resilience and the like. According to the special multifunctional foliar fertilizer for oil-tea trees, the production technology of oil tea can be effectively simplified, the production cost of oil tea can be lowered, and the special multifunctional foliar fertilizer for oil-tea trees has wide application prospects.
