Embodiment 1

[0042] A compound microbial preparation for controlling blue-green algae overgrowth, its proportioning ratio is as follows:

[0043] 12% microbial agent, 77% organic fermented material, 6% brown sugar, 5% trace elements;

[0044] According to the mass percent of described various raw materials, following concrete technical scheme is arranged:

[0045]

[0046]

[0047] A method for preparing a compound microbial preparation for controlling blue-green algae overgrowth, the steps are:

[0048] A. Cultivation of photosynthetic bacteria: inoculate the stock solution of photosynthetic bacteria into a liquid test tube with a cover, culture at 28-30°C for 3-5 days under light to obtain a suspension of photosynthetic bacteria; take 0.1-1% of the suspension of bacteria and put it into 500ml In the inactivated culture medium of the Erlenmeyer flask, use the improved Fan's medium (see Microbiology Experiment Textbook) to proliferate and cultivate in a constant temperature oscillat...

test example 1

[0063] The test site is Jiangxia, Wuhan, with a breeding water surface of 2 mu and a water depth of 1.5 meters. Before application, the algae phase of the water body is mainly blue-green algae, and the water body is aging, with a transparency of only 15 cm. On June 18, 2008, the microbial agent was used, 8KG was used per mu, diluted with 100 times of clear water, and evenly sprinkled in the pond. After 7 days, the transparency increased to 35cm; dissolved oxygen increased from 772mg / L to 1299mg / L; total N, The total P content and permanganate decreased by 30.2%, 28.1% and 17.2%, respectively, and the number of cyanobacteria increased from 53000×10 3 pcs / L down to 9900×10 3 / L, the water body has been significantly improved.

test example 2

[0065] The test site is Makou, Hunan, with a breeding water surface of 80 mu and a water depth of 1.5-2 meters. Before application, the algal phase of the water body is mainly cyanobacteria, and the number of cyanobacteria is 27700×10 3 unit / L, the water body is aging, and the transparency is 25cm; on July 4, 2008, microbial agent was used, 5KG was used per mu, diluted with 100 times of clean water, and evenly sprinkled in the pool. After 5 days, the transparency increased to 40cm; dissolved oxygen increased from 927mg / L increased to 1896mg / L; the number of cyanobacteria decreased to 5200×10 3 / L, the water body has been significantly improved.

Abstract

The invention discloses a compound microbiological preparation and a preparation method for controlling the excessive reproduction of blue-green algae. The preparation comprises the following compounds with a certain weight proportion of microbial agents, organic fermentation agents, brown sugar and micro elements. The preparation steps are as follows: A. the preparation of the microbial agent, B. the preparation of the organic fermentation agent, and then the microbial agent\ fermentation agent, brown sugar and the micro elements are mixed based on a certain weight proportion, and finally, the compound microbiological preparation can be prepared. The preparation has reasonable formulation, is convenient to be used, has no pollution to the water, has high control rate and low cost, and is easy and convenient to be operated.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and more specifically relates to a compound microbial preparation for controlling the excessive reproduction of cyanobacteria in water bodies, and also relates to a preparation method of the biological preparation. , Improve water quality. Background technique [0002] In recent years, with the intensification of surface water pollution and eutrophication of water bodies, the excessive reproduction of cyanobacteria in many lakes, reservoirs, and high-density aquaculture ponds in my country is also a common environmental problem. The overgrowth of cyanobacteria in the water body not only affects the landscape, but also seriously affects the use function of the water body, and directly endangers the aquaculture production. The overgrowth of cyanobacteria is mainly caused by the excessive concentration and improper proportion of nutrients in the water body, which are induced in high temperat...
