Embodiment 1

[0019] 1. Preparation of Compound Amino Acids

[0020] Weigh 100g of dried and pulverized kitchen waste samples, add 550mL of sulfuric acid solution with a mass fraction of 20%, add 2-3g of zeolite, stir, and hydrolyze at 85°C for 12h. After hydrolysis, cool to room temperature. The hydrolyzate uses Ca(OH) with a mass fraction of 30% 2 The solution was neutralized to a pH value of 7, filtered to remove calcium sulfate and unhydrolyzed impurities, and the obtained filtrate was the compound amino acid solution, which was concentrated by evaporation and dried in a thermostat at 45°C for 5 hours to obtain the compound amino acid product.

[0021] 2. Preparation of Nicotine Extract

[0022] Weigh 20g of discarded tobacco leaves and transfer them into a 250ml volumetric flask, add 200ml of hydrochloric acid solution with a mass concentration of 0.03g / ml, shake well for 10min, put it in a constant temperature water bath at 70°C, and extract for 1.5h. After the extraction, the pH o...

Abstract

The invention discloses an organic compound foliage fertilizer and a preparation method thereof. The preparation method comprises the steps of preparing compound amino acid from kitchen wastes through adopting a sulfuric acid hydrolysis method, preparing a nicotine extract from waste tobacco leaves through adopting a hydrochloric acid extraction method, and mixing the compound amino acid with the nicotine extract according to different proportions, wherein the mass proportion of the compound amino acid to the nicotine extract is (1:0.5)-(1:1.5). The organic compound foliage fertilizer is beneficial to promoting the germination of Chinese cabbage seeds and improving the germination rate and germination index; the organic compound foliage fertilizer can obviously promote the growth of leaf mustards and improve the production and quality of the leaf mustards; the organic compound foliage fertilizer plays a role in well promoting the growth of swamp cabbages; the organic compound foliage fertilizer can enhance the resistance of bitter gourds, and relieve the diseases and pests, thus being a desirable foliage fertilizer for producing green food.

Description

technical field [0001] The invention belongs to the field of organic fertilizers, and in particular relates to an organic compound foliage fertilizer and a preparation method thereof. Background technique [0002] Kitchen waste refers to waste products generated during the human diet. Kitchen waste is mainly composed of post-meal waste and food processing waste. Post-meal waste refers to the leftovers discarded by humans after meals, including a large amount of oil and oil-water impurities that cannot be processed and eaten again; food processing waste refers to waste materials generated before and after food processing. In my country, kitchen waste is the main component of urban waste. Kitchen waste has a relatively high moisture content, is easy to rot and emits a strong odor, and seriously affects the social and environmental sanitation. However, from the analysis of chemical composition, kitchen waste contains a large amount of organic substances and rich in trace ele...
