Organic mixed fertilizer capable of controlling white spot of celery

Abstract

The invention discloses an organic mixed fertilizer capable of controlling white spot of celery. The organic mixed fertilizer comprises components of raw materials in parts by weight as follows: 30-40 parts of a molasses fermentation broth, 16-18 parts of a seaweed biogas liquid, 8-10 parts of urea, 5-7 parts of tea leaf residues, 6-8 parts of monopotassium phosphate, 2-4 parts of an antibacterial agent, 2-4 parts of calcium chloride, 2-3 parts of zinc sulfate, 1.2-1.4 parts of lysine, 3-5 parts of humic acid, 2-3 parts of boric acid, 3-5 parts of filler and 5-7 parts of plant ash. The organic mixed fertilizer contains rich nutrient substances, the content of nitrogen, phosphorus and potassium in each litre of the fertilizer is increased to 460 g, the content of the effective ingredients, namely, nitrogen and phosphorus, in a liquid fertilizer is greatly increased, particularly, the content of potassium is greatly increased, the antibacterial agent can effectively control the white spot of the celery and treat various nutritional deficiency symptoms, the disease resistance and adverse resistance of root systems are enhanced, harm caused by diseases and pests is greatly reduced, a water-retaining agent prepared from filler, plant ash and other ingredients facilitates improvement of the soil structure, the air permeability of soil, soil fertility and the water retaining capacity of the soil, and the disease resistance and adverse resistance of plants are enhanced.

Description

technical field [0001] The invention belongs to the technical field of planting nutrient solutions, and in particular relates to an organic mixed fertilizer for preventing and treating white spot of celery. Background technique [0002] During the growth period of celery, especially in the middle and late stages, white spots and hollows often appear on the cross-section of the petiole, or the petiole is cracked horizontally and vertically. The causes and solutions are introduced as follows: This is the main cause of petiole cracking. Solution: Use 0.5-1 kg of borax as the base fertilizer per 667m2. Once a slight crack is found, you can use 0.2%-0.5% borax aqueous solution to spray the leaves, or use 0.25% borax aqueous solution to irrigate the roots. [0003] There are many kinds of liquid fertilizers available, but their effects on improving soil properties and soil living functions are average, and they do not improve the quality of soil environment very well, and cannot ...
