Embodiment 1

[0019] A method for producing an organic fertilizer for preventing pests and diseases, characterized in that it comprises the steps in the following order:

[0020] (1) Extraction of sulfated nicotine: Take tobacco solid waste with a nicotine content of less than 0.8%, extract sulfated nicotine with a concentration of 10% by the horizontal rotation oil immersion method, and then dilute the sulfated nicotine to 0.5% ‰ concentration for later use; the rotary oil immersion method uses a rotary extractor to extract the pretreated tobacco waste with an extractant, and then reacts with dilute acid to obtain 10% sulfated nicotine.

[0021] (2) Pre-fermentation: Take 0.3 tons of cow dung and 0.7 tons of tobacco waste residue after extracting sulfated nicotine, add 2 kg of fermentation strains after mixing, and the fermentation strains can be commercially available conventional strains, and then add 10 kg of fermented loose 10kg fermentation loosening agent is obtained by mixing the fo...

Embodiment 2

[0035] Fermentation bulking agent used in the present embodiment obtains after mixing the following powdery raw materials by following weight percentage: 35% starch, 15% calcium carbonate, 30% ammonium bicarbonate, 5% anhydrous aluminum potassium sulfate, 15% phosphoric acid Calcium dihydrogen, all the other are with embodiment 1.

Embodiment 3

[0037] Fermentation loosening agent used in the present embodiment is obtained by mixing the following powdery raw materials in the following weight percentages: 30% starch, 10% calcium carbonate, 28% ammonium bicarbonate, 10% anhydrous aluminum potassium sulfate and 22% phosphoric acid Calcium dihydrogen, all the other are with embodiment 1.

Abstract

The invention discloses a production method of a pest control organic fertilizer and belongs to the technical field of organic fertilizer production. The production method comprises the following process steps in sequence: (1) extracting nicotine sulfate; (2) performing pre-fermentation, namely mixing cow dung with tobacco waste residues obtained after extracting nicotine sulfate in a weight ratio of 1:3, adding a fermentation strain and a fermentation loosening agent, introducing oxygen and stirring to ferment for 3 days; (3) performing main fermentation, namely adding the fermentation loosening agent into a main fermentation bin, and introducing oxygen to ferment for 18 days; (4) performing secondary fermentation, namely adding the fermentation loosening agent into a decomposition fermentation bin, and introducing oxygen to ferment for 5 days to prepare a decomposed organic fertilizer; (5) compounding, namely adding 0.05% of nicotine sulfate; and (6) crushing and screening. The production method disclosed by the invention can be used for performing full fermentation on the extracted waste residues in tobacco solid wastes, improving the fertilizer effect of the organic fertilizer, and ensuring that the organic fertilizer simultaneously has the beneficial effects of functions of preventing diseases and insects and the like.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer production, in particular to a method for preparing an organic fertilizer for preventing pests and diseases. Background technique [0002] Nicotine, commonly known as nicotine, is an alkaloid found in plants of the family Solanaceae and an important component of tobacco. Yunnan, as one of the main producing areas of tobacco, produces about 100,000 tons of tobacco rebaking and cigarette waste every year, causing environmental pollution and a great waste of resources. Sulphated nicotine is extracted from tobacco rebaking and cigarette solid waste, and its main component is C 20 h 28 N 4 ·H 2 SO 4 , Sulfated nicotine can be used as a non-residue, broad-spectrum insecticide, broad-spectrum green botanical insecticide and antibacterial agent for natural plants that are suitable for a wide range of crops, and the organic matter, nitrogen, and phosphorus in the extracted tobacco residue ...
