Planting method of lemon with strong disease resistance

The invention relates to a planting method of lemon with strong disease resistance. The method comprises the steps of using culture soil of 30-40 years to culture the lemon seedlings, culturing the seedlings for 2-3 months; grafting the cultured seedlings to shaddock seedlings, encapsulating the grafting position of the lemon seedling and shaddock seedling, culturing for 5-6 months to complete the grafting; mixing a fertilizer, wherein the fertilizer comprises, by weight, 5 parts of eggs, 3.5 parts of brown sugar, 5 parts of radices palmae christi, 2 parts of azedarach and 3 parts of stipa sibirica; conducting mixing fermentation for 3-5 months; transplanting the grafted lemon seedlings to an orchard field for germination, and applying culture fertilizer regularly. Compared with the prior art, according to the planting method of lemon with strong disease resistance, the lemon seedling is grated to the shaddock seedling to increase the growth speed. The disease resistance is strong, the adaptable range is wide, and the leaves are small. The fertilizer strengthens the disease resistance of the lemon, and can prevent the soil hardening caused by the applying of too much fertilizer, increase organic substances in the soil, and maintain the ecological balance of the soil.
