The invention discloses a method for quickly forming a
citrus orchard, and belongs to the technical field of
fruit tree cultivation. The method comprises the following steps: 1, strong
seedling selection; 2, mechanical garden building; 3,
rhizosphere soil improvement; 4,
fertilizer and water management; 5, shaping without
pruning; 6, effective control for pest and
disease damage; and 7, tree disk covering. According to the method, basic conditions are created for
rapid expansion of root systems in a mode of preferably selecting strong seedlings and locally improving soil in a root zone,
nutrient supply in the citrus
seedling stage is met, and the tedious procedure of applying base
fertilizer in autumn in the
seedling stage is reduced; a garden building mode of deep
ditch, wide compartment and single-row ridging facilitates mechanical light operation, and the later-stage management and protection cost is greatly reduced; by application of the technology of shaping without
pruning, rapid outward expansion of
plant crowns is realized, and
nutrient waste caused by
pruning is avoided; and high-efficiency management in the seedling stage is achieved through pest and
disease key period control and formulated fertilization technologies, the dosage of chemical fertilizers and pesticides and input of labor force are remarkably reduced, the
plant growth vigor and the fruiting period are 2-3 years earlier than those in the prior art, and early fruiting, high yield and stable yield of fruit trees and
sustainable production of soil are achieved.
