Formula of floc nutrients for cultivating bio-flocs and beneficial bacteria as well as preparation and application

Abstract

The invention provides a formula of floc nutrients for cultivating bio-flocs and beneficial bacteria as well as a preparation and an application. The formula is characterized in that the formula comprises the following components in percentage by weight: 20-40% of puffed corn flour, 5-10% of rice husk powder, 5-10% of humic acid, 40-60% of molasses powder and 10-20% of beneficial bacteria powder; wherein the beneficial bacteria is 1x10<8>-1x10<10> cell / g, and comprises Bacillus cereus, Bacillus licheniformis, Bacillus subtilis, Lactobacillus, and Lactobacillus acidophilus. The floc nutrients are widely applied to water bodies for cultivating prawns, sea cucumbers and fishes, so that formation of bio-flocs in the water bodies is accelerated, ammonia nitrogen and nitrous nitrogen and other harmful substances are rapidly reduced, and directed breeding of beneficial bacteria in the water bodies are improved. The floc nutrients are green and environmentally friendly, and have the advantages of substantially improved production benefits and reduced production cost, wide market prospects, usage convenience; only water is needed for dilution of the floc nutrients, and the diluted floc nutrients are sprayed into cultivation water once a day.

Description

Technical field [0001] The invention belongs to the healthy breeding technology of marine organisms, and specifically relates to a floc nutrient formula for cultivating biological flocs and beneficial bacteria, and a preparation method and application thereof. Background technique [0002] Shrimp is one of the important aquaculture species in my country. In 2012, the national shrimp production reached 1.69 million tons. Shrimp farming has become an important pillar of my country's fishery economy. In recent years, with the rapid development of industry, land and water resources for aquaculture have become increasingly scarce. Intensive shrimp farming under limited farming space conditions has become the development trend of future farming. In the intensive and high-density shrimp culture water, the accumulation of residual bait, feces and excrement will produce a large amount of toxic substances such as ammonia nitrogen and nitros nitrogen, which will seriously affect the normal ...

AI Technical Summary

Problems solved by technology

However, since the current shrimp farming model mostly uses filtered or sterilized water for farming, most of the beneficial bacteria are also removed, resulting in a shortage of beneficial bacteria. , become the limiting factor for the proliferation of beneficial bacteria, so it is difficult to cultivate beneficial bacteria in conventional culture

The practical results also show that even if the beneficial bacteria are splashed in the water body, the detection rate of the corresponding bacteria is extremely low after a few days, indicating that the breeding environment is not suitable for the survival of beneficial bacteria
