Micro-ecologic organic fertilizer fermented from viscera of fish and shellfish and manufacturing method thereof

Abstract

The invention relates to a micro-ecologic organic fertilizer fermented from viscera of fish and shellfish and a manufacturing method thereof and belongs to the technical field of organic fertilizers production. The method includes following steps: (1) performing high-density cultivation and high-spore-rate conversion cultivation to bacillus natto to prepare a high-efficiency fermentation agent; (2) mixing and pre-treating the viscera of fish and shellfish with certain auxiliary materials; (3) adding the fermentation agent with stirring uniformly; and (4) performing constant-temperature stack fermentation to prepare the finish product of the micro-ecologic organic fertilizer. The micro-ecologic organic fertilizer contains not less than 10% of total nutrients including N, P2O5 and K2O and not less than 45% of organic substances, and is not less than 6*10<9> / g in live bacteria number of the bacillus natto. The micro-ecologic organic fertilizer not only includes abundant nutrients required in growth of crops but also has a large amount of probiotics, bacillus natto. By means of the effects of the bacillus natto, the organic substances, which are difficult to absorb, in the soil can be decomposed to generate humus which is absorbable by crops, thereby improving soil structure, enhancing soil fertility and reducing soil bulk density. The micro-ecologic organic fertilizer can improve soil arability so that an urgent demand of green organic agriculture production can be greatly satisfied.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a micro-ecological organic fertilizer fermented by viscera of fish and shellfish and a preparation method thereof, belonging to the technical field of organic fertilizer production. Background technique [0002] my country's modern agriculture is moving towards the direction of sustainable development, but the contradiction between food and the environment is very prominent, which brings many opportunities and challenges to the work of agricultural science and technology. For decades, the enterprise has invested very little in organic fertilizers, almost using "chemical fertilizers and ammonia water" to maintain crop production, resulting in land compaction, soil fertility decline, crop quality degradation, and serious damage to the ecological environment. Seriously restrict the sustainable development of my country's agricultural ecology. At present, people generally complain that excess...

[0005] In recent years, there have been many research reports on organic fertilizers. China invented "an organic fertilizer and its production method". Breeder chicken manure organic fertilizer and its preparation method”, application number 201410098307.X discloses a method of making organic fertilizer with chicken manure, natural zeolite, peat soil, etc.; also uses various raw materials such as pig manure, earthworm dung, tea dregs, etc. Research on the production of organic fertilizer by fermentation; China invented "a conditioner for sludge fermentation organic fertilizer and its production and use method", application number 201110222364.0 discloses a method of using Bacillus natto to produce organic fertilizer through sludge fermentation Method; There are also a lot of studies on the utilization of fish viscera. China invented "a comprehensive utilization method of fish viscera", and the application number 201110309017.1 discloses a method for making feed using fish viscera, but it has not yet been seen that fish and shellfish viscera are used as feed. Raw materials, a report on the production of micro-ecological organic fertilizers by fermentation with Bacillus natto
