Abstract

Disclosed is the preparation process of antidotal bacterium and method for rehabilitation of aquaculture environment, wherein the bacterium can be used for treating the contamination in the cultivation water mass by heavy metals, crop protection products, chlorine preparation. By utilizing the chelation of NTA of the beneficial strains, various toxins can be degraded in a short period of time.

Description

Separate the preparation of toadstool and the method for repairing aquaculture environment

[technical field] and [background technology]

Separating toadstool is the environmental type viable bacteria detoxifcation product of using the modern biotechnology exploitation, be specially at aquaculture pond (pond that particularly coastal groundwater abstraction is cultured) water quality characteristics, employing is based on microorganism, be aided with methods such as chemistry, physics and remove pollutions such as aquaculture water heavy metal, agricultural chemicals, chlorinated product, quaternary amine, eliminate a kind of pond waters detoxifcation microbial inoculum of developing meticulously because of ammonia nitrogen, nitrite, hydrogen sulfide, the rising of algae toxin that water quality deterioration causes.It utilizes gulping down of elite useful bacterial strain counterweight metal to have a liking for the sequestering action of effect and NTA, the various toxin of can degrading at short notice, especially the water pollution that causes because of heavy metal, agricultural chemicals there is tangible detoxification, can recover and improve pond water quality after the use, purify substrate, after useful bacterial strain is preponderated in water body, also can suppress field planting and the invasion and attack of other pathogenic bacterium by nutrient competition, competition for space directly or indirectly, strengthen the vigor of fish, shrimp, crab, shellfish, ginseng.This product is all without any side effects to environment, people, animal, aquatic animal and plant, is repairing aquaculture ecotope, the essential product of producing green aquatic product.

[summary of the invention]

Physicochemical character: black powder.

Main component: genus bacillus, humic acids, NTA etc.

Active constituent content: every gram contains probiotic bacterium 2 * 10 ⁸Individual.

Probiotics of the present invention and preparation method thereof, as follows:

A, liquid culture genus bacillus concentrate the back and use oxalic acid as stopping composition, after the choosing of 80 mesh sieves, and dipping;

B, steps A gained nutrient solution is all poured in the fermentation hole, heap fermentation 15 days shines dry grinding then, and 80 mesh sieves select standby;

C, above-mentioned steps B lay-by material is mixed behind the NTA (heavy metal absorbent) in proportion, stirs, make after the choosing of 80 mesh sieves and separate toadstool.

Effect:

1, eliminate cultivating pool internal cause heavy metals exceeding standard, agricultural chemicals, microbiotic, chlorinated product, quaternary amine is residual and the water pollution that causes.

2, alleviate because of ammonia nitrogen, nitrite in the pond, hydrogen sulfide is higher and the accumulation of algae toxin causes fish, shrimp, crab, shellfish, ginseng and do not take food, vigor is weak, body colour is light, growth waits the distress reaction slowly.

3, nursery pond uses and can increase substantially weed survival rate.

4, the promptly emergency processing of detoxifcation and medicine accident.

This product is without any side effects to aquatic animal, and the repairing aquaculture ecotope promotes healthy aquaculture, improves the essential product of aquatic animal surviving rate, production green aquatic product.

The present invention has strong operability, with low cost, effect is remarkable, to the water surrounding non-secondary pollution, aquatic animal is had no side effect, culture environment of aquatic products there are advantages such as obvious repairing effect, be to comply with current social back to nature, treasure water and life, pursue green food, the development healthy aquaculture, the only way of realizing healthy consumption.

[embodiment]

This invention is applicable to all seas, fresh water aquatic animal nursery pond and growing pond, is specially adapted to that coastal groundwater abstraction is cultured, heavy metal is higher and cultures the middle and later periods the aging pond of " gonorrhoea water ", " red water ", " black smelly water ", " old clear water " occurs.

Consumption:

1, improve water quality: every mu of water surface (1 meter of the depth of water) restrains with this product 250-400, multiplicable splashing during water quality deterioration.

2, grow seedlings: before seedling goes into the pond, every cubic metre of water body 2 grams of splashing.

3, mixed feed uses: every double centner feed uses the 250-500 gram, is mainly used in buffering heavy metal and pesticide intoxication.

Usage: with evenly splashing or mixed feed is thrown something and fed in full pond, 10-20 times of Chi Shui dilution back.

Attention:

1, throws in pharmaceutical chemicals and the antibiotic medicine that bans use of germicidal action in " separating toadstool " first three day, back five days;

2, in the use, the dissolved oxygen in water amount should remain on more than 3 mg/litre, uses in back 3 days and does not change water;

3, use this product not to be subjected to the influence of weather, water temperature, often use can guarantee that water quality is good, avoids poisoning;

4, this product is safe in utilization, multiplicable use during severe water pollution.

Claims

A kind of preparation method of little ecological product comprises the steps:

A, liquid culture genus bacillus concentrate the back and use oxalic acid as stopping composition, after the choosing of 80 mesh sieves, and dipping;

B, steps A gained nutrient solution is all poured in the fermentation hole, heap fermentation 15 days shines dry grinding then, and 80 mesh sieves select standby;

C, above-mentioned steps B lay-by material is mixed behind the heavy metal absorbent in proportion, stirs, make after the choosing of 80 mesh sieves and separate toadstool.
