Problems solved by technology

However, blue-green algae have a high water content and are difficult to dry. After forced drying, they become cakes, and crushing increases the cost.

Embodiment 1

[0021] A preparation method of water hyacinth and blue-green algae composite fermentation organic fertilizer, comprising the steps of:

[0022] (1) Water hyacinth pretreatment: salvage the water hyacinth from the eutrophic water body, drain the water, and then crush and dehydrate it with a squeeze grinder, so that the water content of the water hyacinth is 55-65%;

[0023] (2) Blue-green algae pretreatment: fish out blue-green algae from eutrophic water, drain, and then take 30 parts of drained blue-green algae and 20 parts of rice husks in parts by weight and mix well, so that the rice husks can fully absorb the water in the blue-green algae , after mixing and absorbing water from the chaff, the water content of the cyanobacteria is 75-85%; by draining the water first and then mixing with the chaff, the water content of the cyanobacteria is effectively reduced, and the addition of the chaff not only prevents the cyanobacteria from forming a cake, but also Play the role of loo...

Embodiment 2

[0030] A preparation method of water hyacinth and blue-green algae composite fermentation organic fertilizer, comprising the steps of:

[0031] (1) Water hyacinth pretreatment: salvage the water hyacinth from the eutrophic water body, drain the water, and then crush and dehydrate it with a squeeze grinder, so that the water content of the water hyacinth is 55-65%;

[0032] (2) Blue-green algae pretreatment: fish out blue-green algae in eutrophic water body, drain, and then take 50 parts of drained blue-green algae and 40 parts of rice husk in parts by weight and mix well, so that the rice husk can fully absorb the water in the blue-green algae , after mixing and absorbing water from the chaff, the water content of the cyanobacteria is 75-85%; by draining the water first and then mixing with the chaff, the water content of the cyanobacteria is effectively reduced, and the addition of the chaff not only prevents the cyanobacteria from forming a cake, but also Play the role of lo...

Abstract

The invention discloses a preparation method of a water hyacinth and blue-green algae compound fermentation organic fertilizer. The preparation method includes the steps: (1) pre-treating water hyacinths; (2) pre-treating blue-green alga; (3) preparing mixed materials; (4) fermenting pretreated mixed materials; (5) performing puffing for the fermented mixed materials; (6) granulating. According to the preparation method of the water hyacinth and blue-green algae compound fermentation organic fertilizer, by the aid of pretreatment before fermentation and chaff mixing modes, the water content of the blue-green alga is effectively reduced without increasing crushing cost, chaff is added, so that the blue-green alga cannot change alga cakes, loosening and ventilating functions are achieved, and mineral fertilizers and microelement additives are used, so that the prepared organic fertilizer is rich in nutrition element, high and uniform in effect and durable in fertility.

Description

technical field [0001] The invention relates to the technical field of organic fertilizer preparation, in particular to a method for preparing fermented organic fertilizer with water hyacinth and blue-green algae as main raw materials. Background technique [0002] In recent years, the degree of eutrophication in my country's water bodies has become increasingly serious, and the problem of water shortage has become increasingly prominent. What's more serious is that the accompanying organisms of water eutrophication - water hyacinth, blue-green algae, etc., grow at a very crazy speed. If they are not salvaged in time, they will not only block the river due to covering the water surface, affect shipping, and hinder flood discharge, but will also be destroyed by water pollution. Destroying the balance of water ecosystems and reducing biodiversity will have far-reaching and extensive negative impacts. [0003] Water hyacinth has a strong enrichment effect on many elements in t...
