Embodiment

[0017] A preparation method of organic fertilizer, comprising the steps of:

[0018] 1) Smash, sieve, and sterilize the pulp residue, mushroom residue and seaweed residue respectively, add a starter, mix well, add water and adjust the water content to 20-30wt%, and ferment at 30-40°C for 3-5 days to obtain pre-fermentation thing;

[0019] 2) Determining the nitrogen, phosphorus and potassium content of the pre-fermented product, and weighing the pre-fermented product according to the proportioning ratio of the final nutrient of the organic fertilizer;

[0020] 3) Mix the weighed pre-fermented products evenly, add water and adjust the water content to 55-60wt%, stack and ferment, turn the fermented products after the fermentation temperature rises to 60°C, and ferment for 8-12 days to obtain The decomposed matter is granulated, air-dried, cooled and sieved to obtain the finished organic fertilizer.

Abstract

The invention discloses a preparation method of organic fertilizer. The preparation method comprises the steps as follows: pre-fermentation of fermentation components, determination and accurate weighing of nitrogen, phosphorus and potassium of pre-fermented materials, fermentation of organic fertilizer and the like. The preparation method has the beneficial effects as follows: by accurately determining the proportion of the to-be-fermented components, the carbon-nitrogen ratio of the pre-fermented materials is reasonable, zymocyte activity is high, and accordingly, organic matter can be fully decomposed, and organic fertilizer efficiency is high; the organic fertilizer with special nutrient ratio can also be designed according to specific applications of the organic fertilizer, the defects of insufficient fermentation and unreasonable nutrients caused by the rough proportion of existing organic fertilizer are overcome.

Description

technical field [0001] The invention relates to the field of organic fertilizers, in particular to a method for preparing organic fertilizers. Background technique [0002] During the growth of crops, regular fertilization is required to ensure the yield. At present, chemical fertilizers are mainly used in agriculture. Although chemical fertilizers can increase production, a large amount of them will cause serious damage to the soil, such as environmental pollution, element imbalance, soil compaction, etc. . The use of organic fertilizers can alleviate the above problems to a large extent. The raw materials of organic fertilizers are cheap and easy to obtain. Generally, livestock and poultry manure, agricultural product waste, garbage and other substances with high organic matter content are used. The use of organic fertilizers can improve the soil environment and improve the utilization efficiency of agricultural and sideline products. It is a green and environmentally fri...
