Case analysis

 


 

 

 

1. Over-breeding moss will absorb a large number of nutrients in the water body, and will cover the water surface to reduce the light intensity, hinder the photosynthesis of algae, affect the growth of algae, resulting in thin water.

Too much moss will reduce the living space of breeding animals. When the moss is attached to the prawn's cheek, it seriously affects the respiration of the prawn and even causes the prawn to suffocate.

3. The cause of the outbreak of moss: If the pond mouth is not thoroughly exposed and cleared, or the spores of moss enter the pond mouth through exogenous water, and the water quality is lean in spring and the fertilizer and water are not timely, the moss spores will germinate and multiply in large quantities as the temperature rises.

4.Carex netFor plant extracts, safe and efficient does not hurt shrimp seedlings. Carex net for small particles, easy to use, focus on the growth of moss can be thrown.
