Abstract

The invention discloses an organic fertilizer for preventing and controlling citrus leaf tip yellowing, and a preparation method thereof. The organic fertilizer is prepared from 60-90 parts of a compound fertilizer, 30-40 parts of an organic fertilizer, 1-5 parts of nano-cellulose, 2-5 parts of Bacillus subtilis, 5-10 parts of humic acid, 20-30 parts of sawdust, 1-10 parts of Forsythia suspense leaf and Scutellaria baicalensis extract, 1-5 parts of an insecticide and 100-150 parts of a carrier. The organic fertilizer can regulate the plant growth, control physiological diseases, facilitate supplementation of necessary nutrient elements for plants, reduce the use amount of fertilizers and reduce the pollution of agricultural chemicals to soil and underground water; and the organic fertilizer can supplement nutritional ingredients required by oranges in each growth period, so the oranges can quickly and fully obtain the required nutritional ingredients in each growth period, the nutrition balance is kept, the soil environment of orange roots can be improved, healthy and strong roots can be promoted, and the yellowing of oranges can be prevented and controlled.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to an organic fertilizer for preventing and treating citrus leaf tip yellowing, a preparation method and an application method thereof. Background technique [0002] The yellowing of citrus can be divided into three categories: mottled yellowing, uniform yellowing and deficiency yellowing. The yellowed branches and leaves begin to yellow near the veins, the base or edge of the leaves, and gradually spread to form yellow and green mottled diseased leaves, and finally develop into uniform yellowing. After the yellow shoots and mottled yellowing of the young trees, the summer shoots or autumn shoots that occurred on them will remain green near the main veins and branches of the leaves, and the rest will be yellowed, and the whole leaf will appear as a deficiency yellow. The veins of yellowed and yellowed leaves are swollen and protruding, and the cork is cracked locally. The ne...
