Embodiment 1

[0026] The preparation of the above-mentioned benthic bait biological medium for river crab culture comprises the following steps:

[0027] Step S1. Prepare the humic acid-bentonite complex, add the bentonite to the humic acid solution with a concentration of 100mg / L according to the amount of 100g bentonite added to 1500mL humic acid solution, and stir for 3h on a magnetic stirrer, then in Centrifuge at 3500r / min for 5min, remove the lower layer of sediment, and dry to obtain the humic acid-bentonite complex, which is ready for use;

[0028] Step S2. Place 5 parts of aquatic plants and 10 parts of rape stalks in a dryer to dry at 100°C, and then place the dried water plants and rape stalks in a pulverizer to pulverize to obtain a mixture of water plants and rape stalks. use;

[0029] Step S3. Put the attapulgite in a roasting furnace and roast at 450° C. for 2 hours to obtain the modified attapulgite for use;

[0030] Step S4. Dry 1 part of Astragalus membranaceus, 1 part o...

Abstract

The invention relates to a benthic bait organism culture medium for river crab culture. The culture medium is prepared from the following raw materials in parts by weight: 10-20 parts of rice bran, 10-30 parts of soybean meal, 5-10 parts of aquatic plants, 5-15 parts of rape stalks, 10-30 parts of vinasse, 3-5 parts of fluorite powder, 0.5-1 part of milk-vetch root, 0.5-1 part of Chinese wolfberryfruit, 0.5-1 part of folium artemisiae argyi, 5-8 parts of modified attapulgite, 2-3 parts of enzyme-producing probiotics and lactic acid bacteria, 2-3 parts of a phagostimulant and 3-6 parts of a humic acid-bentonite complex. The preparation method is simple and convenient, materials are easy to obtain, and large-scale production is facilitated. The benthic bait biological culture medium for river crab culture can improve the bottom material and water quality of a pond, promote the growth of river crabs, improve the immunity of the river crabs, reduce the morbidity rate, and solve the problem of water pollution.

Description

technical field [0001] The invention relates to the technical field of biological culture medium, in particular to a benthic bait biological culture medium for river crab cultivation. Background technique [0002] In recent years, due to the improvement of people's living standards, the demand for aquatic products is increasing, but the supply of natural aquatic products is in short supply, and many river crab breeding areas are difficult to meet people's demand for river crabs. The key control technologies for the healthy cultivation of river crabs include: disinfection of clear ponds and biodegradation, fertilized hydroponic algae and health care seedlings, optimization of crab seedlings, selection of grasses and grasses, health care of snails, maintenance and improvement of bottom water quality, prevention and control of shelling, The ten aspects of cultivating nutrients, detoxification and detoxification, anti-stress, supplementing nutrition, enhancing immunity, promotin...
