The invention belongs to the technical field of planting, and discloses a high-yield planting method for improving the
disease resistance of Citrus. The high-yield planting method comprises the following steps: 1) selecting and
processing cultivating land, selecting the sandy land for
tilling, and applying sufficient decomposedmanure, digging holes according to the row spacing of (2-3) * (3-4)m, applying2-5 kg of superphosphate and 2-3 kg of
plant ash for per hole; 2)
transplanting and planting;
transplanting and plating between late August and early September, or between February and March, and applying
nutrient solution at the same time; 3) applying
fertilizer; applying compound
fertilizer in the
germination period by 0.5-1.2kg / tree; applying
calcium orthophosphate in the florescence period by 0.3-0.6kg / tree, and applying
boric acid with a
mass concentration of 0.3-0.5% and
disease-resistance nutritional agents with the
mass concentration of 0.3-0.5% by means of foliar spraying; applying foliar
fertilizer with a concentration of 0.3-0.5% during the fruit expansion stage; applying fruit expanding fertilization during full bearing period by 0.5-1.5kg / tree; 4)
insect killing; preparing the
insect-
resist agents from probiotics,
indole acetic acid, Chinese
medicine extract and
carbendazim. The high-yield planting method for improving the
disease resistance of citrus has the advantages that the yield and quality of citrus is significantly improved; the disease-resistance of citrus is improved and the fragrance and the
sweetness of the fruits are greatly improved.
