Embodiment 1

[0023] Embodiment 1: A kind of preparation method of vermicompost organic fertilizer based on water hyacinth

[0024] This method consists of the following steps in order:

[0025] (1) Water hyacinth is salvaged and collected manually or mechanically.

[0026] (2) After the fresh water hyacinth is collected, carry out mechanical homogenization and crushing treatment to destroy the plant tissue and promote rot; or stack the whole water hyacinth and spray rot-promoting bacteria (such as "Reilite" rot-promoting agent) and cover it with plastic Film promotes pretreatment of water hyacinth for rapid rot pretreatment.

[0027] (3) The pretreated water hyacinth is added with cow manure in a weight ratio of 80:20, and the water hyacinth and cow manure are mixed and piled into a width of 1m and a height of 1m, and conventional aerobic fermentation is carried out, and the earthworm bait based on water hyacinth is piled up. 70%.

[0028] (4) The water hyacinth bait is stacked into a s...

Embodiment 2

[0045] Embodiment 2: A kind of preparation method of vermicompost organic fertilizer based on water hyacinth

[0046] (1) 700kg of fresh water hyacinth, about 95% moisture, beating, chopping, or adding a quick putrefaction agent for rotten pretreatment.

[0047](2) 300kg of cow feces, about 75% of the moisture content, slightly turned in the sun to reduce the moisture content, and set aside.

[0048] The preparation method is to mix the pretreated water hyacinth and cow manure evenly for conventional aerobic fermentation, about 10 days, and cover the film at the beginning of fermentation; pile the fermented water hyacinth milk cow dung bait into a strip-shaped vermicomb bed or pile it up Put 100kg of bait with a humidity of 70% in the culture tray, 9000 seed worms with a unit weight of about 0.28g, about 2.5kg; the humidity of the worm bed is adjusted to about 73%, the pH value is 7-8, and the temperature is 25-26°C; When the weight of most of the earthworms in the worm bed h...

Embodiment 3

[0050] (1) 900kg of fresh water hyacinth, about 95% of water content, beating, chopping or adding quick putrefaction agent for rotten pretreatment.

[0051] (2) 100kg of pig manure, about 72% of water content, slightly turned in the sun to reduce water content, set aside.

[0052] Preparation method: use this raw material ratio to prepare according to the preparation method in Implementation 1.

Abstract

The invention provides a method for preparing a wormcast organic fertilizer based on water hyacinths, and belongs to the organic fertilizer manufacturing field. The collected water hyacinths are crushed or / and decayed to obtain the water hyacinth raw material; the water hyacinth raw material is mixed with animal waste according to the weight proportion of 70-90:10-30, and aerobic fermentation is carried out to obtain earthworm food, the water content of which is 65 to 75 percent; the earthworm food is heaped into an earthworm bed; eisenia fetida earthworms are put onto the earthworm bed; the water content, the pH valve and the temperature of the earthworm food in the earthworm bed are controlled to 65 to 75 percent, 6.5 to 8.0, and 18 DEG C to 26 DEG C respectively; the earthworm food is changed into wormcast, and then the wormcast is collected to obtain the organic fertilizer. The invention provides a novel technical approach for the water hyacinth resource utilization, realizes in situ growth and large-scale production of the water hyacinth and efficient utilization of the fertilizer source, improves economic benefits of the utilization of water hyacinth resources, and promotes the sustainable development of the modern agriculture.

Description

technical field [0001] The invention relates to a fertilizer preparation method characterized by biological fertilizer preparation steps, in particular to a water hyacinth-based vermicompost organic fertilizer preparation method, which belongs to the technical field of organic fertilizer production. 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 water hyacinth (also known as water hyacinth) grows at a very crazy speed. If it is not salvaged in time, it will not only block the river due to covering the water surface, affect shipping, and hinder flood discharge, but also Destroying the balance of water ecosystems and reducing biodiversity due to water pollution has far-reaching and extensive negative impacts. For this reason, dealing with water hyacinth has become a very difficult problem. ...
