A practical case of Bacillus species inhibiting blue-green algae in Yangzhou
Practical case of Bacillus species inhibiting blue-green algae in the Yangzhou area
(Agricultural Wealth Network) 1. Basic pond information:
Boss Che of Zhoushan, Gaoyou raises Macrobrachium rosenbergii (giant freshwater prawn) in a total of 50 mu, including two ponds of 40 mu and 10 mu. Both ponds have a water depth of 80 cm. The pond water color is somewhat blue-green, with a layer of green oil film floating on the surface of the pond water, and some granular blue-green algae in the downwind area of the pond.
2. Treatment method:
1. For the 40-mu shrimp pond, use 4 bottles of Bacillus species. Take surface water from the pond and add brown sugar (10:1 ratio), then add the Bacillus species and culture for 24 hours, that is, the next day, dilute in water and splash over the whole pond.
2. For the 10-mu shrimp pond, use 5000 ml of ordinary EM stock solution produced by a certain manufacturer, directly dilute in water and splash over the whole pond.
3. Application effect:
In the 40-mu shrimp pond, after using the Bacillus species, on the afternoon of the same day, the green oil film on the pond water surface disappeared; the next day the pond water turned to a healthy yellow-green water color.
4. Summary:
1. After simple culture for 24 hours, the Bacillus species forms a high-concentration Bacillus liquid. After being put into the shrimp pond, Bacillus can rapidly form a dominant population in the pond water, consuming a large amount of nutrients and organic matter in the water, thereby inhibiting the excessive reproduction of blue-green algae and also avoiding the green oil film on the surface of the pond water.
2. The ability of Bacillus liquid cultured from Bacillus species to purify water quality is far higher than that of ordinary EM stock solution. The freshly prepared and immediately used Bacillus liquid has characteristics such as high freshness and strong activity; while ordinary EM liquid, as the storage time lengthens, the live bacteria in it begin to age and die, and by the time it is used, only some nutrients remain, while the active content is quite low.
