preparation example Construction

[0043] The preparation method of this water quality improving bacterium containing alginic acid comprises the steps:

[0044] (1) Select clean seaweed, wash it with a dilute acid solution with pH 2-4, mince and grind; add alkali to adjust the pH to 5.0-7.5; add 5% Bacillus subtilis to ferment for 2-3 days to obtain seaweed extract;

[0045] (2) Take 20 parts of soybean meal, 10 parts of rapeseed meal, 20 parts of distiller's grains, 45 parts of rice bran, and 5 parts of Bacillus subtilis, adjust the moisture content to 55%, turn over and ferment for 10-15 days, crush through a 2mm sieve, and make get fermented organic matter;

[0046] (3) Mix photosynthetic bacteria, lactic acid bacteria, Bacillus subtilis, and Bacillus licheniformis in a weight ratio of 2:3:3:2 to obtain a composite microbial agent;

[0047](4) In parts by weight, 12 parts of seaweed extract, 22 parts of water-soluble organic matter, 33 parts of fermented organic matter, 25 parts of micropore protective agen...

Embodiment 1

[0050] Experimental location: Youli Village, Sunqiao Town, Shayang County, Jingmen City, Hubei Province

[0051] Overview of the test pond: Intensive culture pond with an area of ​​3 mu. The pond was dug in September 2018 and watered in mid-October. The water depth was 1.0m, and 90kg of seeds were cast, about 3600 tails. In mid-to-late November, moss sprouts at the bottom and the water is crystal clear.

[0052] Test process: Sampling water quality, testing water temperature, transparency, ammonia nitrogen, nitrite, hydrogen sulfide, dissolved oxygen, and microalgae as background data; then applying water quality improver 5kg / mu, and on December 7, 2018, again Take mixed samples at the same location, test various indicators of water quality, and observe changes in moss and water color.

[0059] Experimental site: Gugu Village, Ganyi Town, Tianmen City, Hubei Province

[0060] Overview of the test pond: the test field and the control field are both shrimp paddy fields, with an area of ​​5 mu, a 3-year-old pond, and a small amount of moss in the ring ditch; at noon on March 3, the test field and the control field were sampled and tested as background data, and the water quality improvement bacteria were applied to the test field 25kg, a certain brand of water-improving fungicide was applied to the control field. On 3.8, 50,000 juvenile shrimps of 2-4 cm were put in. On 3.10, water quality data such as water temperature, transparency, ammonia nitrogen, nitrite, hydrogen sulfide, dissolved oxygen, and microalgae were tested by sampling the control field and the experimental field.

Abstract

The invention discloses a water quality improving microbial agent capable of achieving biological modification and alga culture. The water quality improving microbial agent includes the following rawmaterials: in parts by weight, 10-15 parts of seaweed extract, 20-30 parts of water-soluble organic matter, 30-45 parts of fermented organic matter, 25-30 parts of a microporous protective agent, 3-5parts of alga growth promoting factors and 3-5 parts of a compound bacterial agent. The invention also discloses a preparation method of the water quality improving microbial agent capable of achieving biological modification and alga culture. The water quality improving microbial agent is capable of activating the activity of microorganisms in the water body and improving nutrient circulation, and has the dual effects of promotion of the biological improvement and water quality through combination of two forms of carbon sources, the seaweed extract is contained, and the water quality improving microbial agent has the effect of promotion of the growth of microalgae and water plants at low temperatures, so that excellent water color is formed quickly.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizer production, in particular to a bio-algae water-quality-improving microbial agent and a preparation method thereof. Background technique [0002] In 2018, the total output of aquatic products in my country was 64.4533 million tons, of which, the output of aquaculture was 49.0599 million tons, accounting for 76.12% of the total output, and the output of fishing was 15.3934 million tons, accounting for 23.88% of the total output. It is the only major fishery country in the world where the total amount of aquaculture products exceeds the total catch. Among the total output, the output of marine products was 33.2174 million tons, accounting for 51.54% of the total output, and the output of freshwater products was 31.2359 million tons, accounting for 48.46% of the total output. It is worth noting that in order to solve the outstanding problems faced by the green development of aquacultur...
