Embodiment 1

[0029] Put the water hyacinth salvaged by the salvage ship into the screw extrusion crusher to squeeze and dehydrate, so that the water content of the water hyacinth can be reduced to about 60%; according to the weight of the water hyacinth after dehydration, add the fermented pig manure , to get the water hyacinth mixture, the weight in the fermented pig manure in the water hyacinth mixture is about 30%), after the two are evenly mixed, enter in the tank type fermentation tank and carry out composting fermentation; When the temperature is 50 degrees Celsius, use the turning equipment to turn the pile for oxygen supply and further dehydration; when the temperature rises to 60-70 degrees Celsius, turn the pile twice a day, and if you smell the smell of ammonia, you need to adjust the acid; when the temperature of the pile body is from 60- 70 degrees Celsius down to near room temperature, the material has no peculiar smell, the color turns brown, and the fermentation process is o...

Embodiment 2

[0033] The water hyacinth is extruded and crushed, dehydrated to about 70% water content, and then mixed with fermented sheep manure. In the mixed material, the weight ratio of sheep manure is 30%-50%. After mixing evenly, it enters the tank Composting fermentation, all the other steps are the same as embodiment one.

Embodiment 3

[0035] Squeeze and crush the water hyacinth, dehydrate it to a water content of about 55%-75%, and then mix it with the garbage dump. Add garbage compost to the mixed material at a weight ratio of 20%-40%. After mixing evenly, enter the tank Formula composting fermentation, all the other steps are with embodiment one.

Abstract

The invention relates to a method for producing an organic fertilizer by using water hyacinth as a raw material and mixed composting fermentation. The method comprises the following steps of: crushing and dehydrating the water hyacinth salvaged by a salvage boat, and adding the fermented animal dung into the crushed and dehydrated water hyacinth; after uniform mixing, feeding the mixture into a groove-shaped fermentation tank to perform composting fermentation; when the temperature of the materials is raised to between 40 and 70 DEG C, performing turning oxygen supply by using a turning device and performing further dehydration; when the temperature is raised to between 60 and 70 DEG C, turning the mixture twice every day; and after the fermentation is finished, obtaining an organic fertilizer product by direct packing or crushing and packing or extrusion and granulation according to different purposes. The method is simple and feasible, can realize resource utilization of the water hyacinth, does not produce secondary pollution, and provides the safe and pollution-free fertilizer for agricultural production when solving the pollution problem.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and relates to a method for producing organic fertilizers by using water hyacinth as a raw material, mixing livestock and poultry manure, composting and fermenting, for nourishing plants and fertilizing soil. Background technique [0002] Water hyacinth [Eichhornia crassipes (Martius) Solms-Laubach], also known as water hyacinth, water hyacinth (blue), false narcissus, foreign narcissus, water (raw) hyacinth, water lotus, bag lotus, etc., is a monocotyledonous plant , Hyacinthaceae Hyacinthaceae. Native to South America, it begins to reproduce at a temperature of 13°C and can still reproduce at a temperature of 39°C. It is one of the fastest growing and multiplying aquatic plants in the world. It was introduced from South America in the 1930s when there was an extreme shortage of food in my country. It was promoted as livestock and poultry feed in the 1960s and 1970s. In recent years, due...
