A practical case of Bacillus strain inhibiting blue-green algae in Yangzhou area

(agricultural get Rich Network) 1. Basic situation of ponds:

Gaoyou Zhoushan car boss raised Macrobrachium rosenbergii in a total of 50 mu, including 40 mu and 10 mu of two ponds, both of which are 80cm in depth. The water color of the pond is a little blue-green, there is a layer of green oil film on the surface of the pond, and there are some granular blue-green algae in the downwind of the pond.

Second, the method of treatment:

4 bottles of Bacillus were used in shrimp ponds with 1 and 40 mu of water surface. Take the surface water of the pond and add brown sugar (10:1 ratio), then put in the bacteria, culture for 24 hours, that is, the next day, sprinkle the whole pond with chemical water.

2, 10 mu of water in the shrimp pond, using the common 5000mlEM solution produced by a factory, directly sprinkle the whole pond with water.

3. Application effect:

The green oil film on the surface of the pond disappeared in the afternoon after the use of Bacillus in the 40-mu shrimp pond, and the water changed to a healthy yellowish green color the next day.

IV. Summary:

The main results are as follows: 1. After simple culture for 24 hours, Bacillus forms a high concentration of Bacillus liquid. After it is put into the shrimp pond, Bacillus can quickly form the dominant population in the pond water and consume a large amount of nutrients and organic matter in the water. Thus inhibit the excessive reproduction of blue-green algae, but also avoid the green oil film on the surface of the pond water.

2. The ability of purifying water quality of Bacillus solution cultured with Bacillus is much higher than that of ordinary EM solution. The current bacillus solution has the characteristics of high freshness and strong activity, while the ordinary EM solution begins to age and die with the extension of storage time. When used, only some nutrients are left, while the activity content is quite low.
