Photosynthetic bacterium pond head expanding culture medium and method for preparing photosynthetic bacterium liquid by using same

Abstract

The invention discloses a photosynthetic bacteria pond head expanding culture medium. The photosynthetic bacteria pond head expanding culture medium comprises an aqueous solution, and is characterizedin that each liter of the aqueous solution comprises the following components by mass of 3.0-6.0 g of anhydrous sodium acetate, 2.0-4.0 g of sodium bicarbonate, 1.0-1.5 g of ammonium chloride, 0.5-1.0 g of potassium dihydrogen phosphate, 0.1-0.5 g of anhydrous magnesium sulfate, 0.5-1.2 g of sodium chloride, 0.1-1.0 g of yeast hydrolysate, 0.001-0.01 g of complex vitamin B, 0.1-0.5 g of anhydroussodium thiosulfate. The yeast hydrolysate and the vitamin B complex are used for replacing yeast extract, and the raw materials can be directly mixed together. The anhydrous sodium thiosulfate is added to provide nutritional ingredients and neutralize residual chlorine, tap water is directly used for expanding culture, and advanced aeration or airing is not needed. The invention aims at solving the problems that when photosynthetic bacteria are used for regulating water quality in aquaculture, most of farmers directly use stock solutions, the cost is relatively high, the bacteria number is not high after liquid seeds are stored for a long time, and the activity is relatively low, so that the use effect is poor.

Description

technical field [0001] The invention belongs to the application technology development of photosynthetic bacteria in aquaculture, and specifically relates to a photosynthetic bacteria pond head expansion culture medium for aquaculture, a method for preparing photosynthetic bacteria liquid by using the expansion culture medium, and using photosynthetic bacteria liquid to treat thick green water or The method of thick turbid water. Background technique [0002] At present, the application of photosynthetic bacteria in aquaculture is mainly to directly splash liquid strains, resulting in high cost of cultivation. Considering the cost of use, users use very little per mu. In addition, some farmers do not have the habit of using bacteria, which often results in poor results. generally. On the other hand, the shelf life of liquid fungus products (including: lactic acid bacteria expansion culture solution) is generally only about three months, and the content of live bacteria afte...

Problems solved by technology

The primary productivity of such ponds is low, the dissolved oxygen in the pond is insufficient, fish diseases occur frequently and the feed ratio is high, which increases the risk and cost of breeding
