Embodiment 1

[0015] Concrete preparation method comprises the following steps:

[0016] 1. Scientific compatibility to produce compound functional strains with higher performance

[0017] According to different strains selected: Bacillus subtilis, Rhodopseudomonas palustris, Thiobacillus.sp, Lactobacillus.sp and Photosynthetic bacteria abbr Functional research, combined with different composite bacterial agents. Using the water of cyanobacteria blooms (mainly Oscillatoria and Microcystis) as the base water, with different bacterial strain combinations under different culture salinity and different culture temperature conditions, the content of chlorophyll a and total nitrogen in the water after 72 hours , The content of total phosphorus is a comprehensive test for the determination index to obtain the best combination.

[0018] 2. Preparation of probiotics

[0019] Under aseptic conditions, combine the best combination of strains obtained, the mass ratio of each strain is 1:1:1:1:1, mak...

Embodiment 2

[0020] Embodiment 2: Saline-alkali water application test

[0021] Test time: from October 20th to October 23rd, 2010.

[0022] Test site: Ma Village, Yanshan County

[0023] Test method and process: Two breeding ponds were selected, one was labeled 1# for the experimental group, and the other was labeled 2# for the control group. In the 1# test pond, use this bacterial agent in the morning, the dosage is 1000mL per mu (1 meter water depth), the usage is to dilute and sprinkle the whole pond, sprinkle more in the downwind area, and turn on the aerator at the same time. 2# is the control pond. Copper sulfate was used in the morning, and the dosage was 500mL per mu (1 meter of water depth). The experimental results are shown in Tables 1 and 2.

[0025]

[0026]

[0027] Table 2 Test changes of 2# pool

[0028]

[0029] The test results show that the bacterial agent can effectively inhibit the growth of blue-green alg...

Embodiment 3

[0030] Embodiment 3: fresh water application test

[0031] Test time: August 6th to 8th, 2009.

[0032] Test site: Li Lixin Farm, Eleven Field, Tanghai County, Tangshan City, Hebei Province

[0033] Test method and process: Two breeding ponds were selected, one was labeled 1# for the experimental group, and the other was labeled 2# for the control group. In the 1# test pool, use this preparation in the morning, the dosage is 1000mL per mu (1 meter water depth), the usage is to dilute the whole pool and sprinkle more, and turn on the aerator at the same time. 2# is the control pond. Copper sulfate was used in the morning, and the dosage was 500mL per mu (1 meter of water depth). The experimental results are shown in Table 3.

[0034] Table 3 Freshwater application test results

[0035]

[0036] The results of the freshwater application test can also show that the preparation is more applicable than the commonly used chemical reagent copper sulfate, and can control the am...

Abstract

The invention discloses a micro-ecological preparation for inhibiting cyanobacteria. The complete formula of the preparation includes bacteria species: Bacillus subtilis, Rhodopseudomonas palustris, Thiobacillus.sp ), Lactobacillus (Lactobacillus.sp) and compound photosynthetic bacteria (Photosynthetic bacteria abbr). The preparation can effectively inhibit the growth of cyanobacteria, effectively control the content of ammonia nitrogen and hydrogen sulfide, significantly increase the content of dissolved oxygen, improve water quality, and improve breeding benefits.

Description

technical field [0001] The invention relates to the technical field of water quality purification, in particular to a microecological preparation for inhibiting cyanobacteria. Background technique [0002] Cyanobacteria are prokaryotes, also known as blue-green algae and cyanobacteria, including Cyanococcus, Oscillating Algae, Nostoc, and Microcystis. It is widely distributed and spread all over the world. In the aquaculture environment and nutrient-rich natural waters, it often breeds in large numbers in summer, forming a layer of blue-green and fishy-smelling floating foam on the water surface, called "water bloom", which causes water quality. Deterioration, when severe, depletion of oxygen in the water causes the death of aquatic animals such as fish, shrimp and crab. What's more serious is that some species of cyanobacteria (such as Microcystis) also produce toxins (MC). After drinking water containing algae toxins, domestic animals and wild animals will experience diar...
