High yield planting method for improving disease resistance of citrus

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a high-yield planting method for improving the disease resistance of citrus. Background technique [0002] Citrus belongs to Rutaceae Citrus subfamily, which is the general name of tangerine, tangerine, orange, kumquat, pomelo, and trifoliate. my country is one of the world's citrus origin centers, with a cultivation history of more than 4,000 years. Its planting area has reached 2.9 billion mu, with a total output of 19.41 million tons, ranking first in the world in both area and total output. However, during the development of my country's citrus industry, some problems have also been exposed, such as relatively low product output and product quality that needs to be improved; the main reasons for the low per unit yield and poor product quality are cultivation problems, including planting technology, fertilization treatment and pests and diseases. Prevention and treatment. In...

Problems solved by technology

In the existing citrus cultivation methods, citrus trees cannot perform photosynthesis well, and citrus trees are not easy to accumulate nutrients, resulting in relatively weak crown growth, greatly reduced flowering and fruiting, and a large amount of weeds are likely to be produced between citrus trees. wood, competes with citrus trees for nutrients, and at the same time provides more habitats for pests and diseases, causing severe pests and diseases of citrus trees.
