A kind of preparation method of water earthworm culture substrate

Abstract

The invention discloses a Limnodrilus hoffmeisteri culture medium and a production method thereof. The Limnodrilus hoffmeisteri culture medium is composed of, in percent by weight: 66-72% of rolled straw and rapeseed cake fermented mixture, 18-24% of fermented pig manure and 10% of earth, wherein half of the earth is spread at the bottommost layer, and the rolled straw and rapeseed cake fermented mixture, the fermented pig manure and the other half of the earth are sequentially and evenly spread on the bottommost layer of earth. In the rolled straw and rapeseed cake fermented mixture, a mass ratio of rolled straw and rapeseed cake is 9:1, and the rolled straw and rapeseed cake fermented mixture is made by fermenting mixed bacterial solution of white-rot fungus and Trichoderma viride. The fermented pig manure is made by: stacking pig manure in a pool or pit, spilling a layer of lime per layer of pig manure, and sealing and compressing with plastic film, and fermenting for a month, wherein the total mass of the lime is 5% of that of the pig manure.

Description

technical field [0001] The invention relates to a substrate for cultivating water worms and a production method thereof, in particular to a biological substrate for cultivating water worms with rubbed straw as a loosening agent and a production method thereof. Background technique [0002] Water earthworms, also known as silk earthworms, red nematodes, etc., are worm-like animals. Their nutrition is comprehensive, the dry product contains 62% crude protein, 35% of various essential amino acids, and the total fat content is 2-4% of other freshwater plankton. It is an excellent natural bait for economical aquatic products such as turtles, shrimps, crabs, eels, eels, sturgeons, and giant salamanders, especially for freshwater bottom fish. [0003] In recent years, with the development of famous and high-quality aquatic product aquaculture, water worms are more and more favored by farmers. Water earthworms reproduce quickly and have high nutritional value. They are the open bai...

Problems solved by technology

Straw resources such as rice in rural areas are completely in a state of high consumption, high pollution, and low output. Most of them are burned in the field and have not been rationally developed and utilized.

At the same time, during the combustion of straw, a large amount of soot, particulate matter, carbon dioxide, carbon monoxide and other pollutants will be produced, which will hinder the driving of cars on the expressway and the take-off and landing of aircraft.
