Clearing pond medicine-tea meal
Pond cleaning and disinfection generally use quicklime and bleach to clean the pond, but if the pond is used for 234 waste water, the effect of cleaning the pond with tea meal can not be replaced by other drugs, the effect is better.
Tea meal, also known as tea seed cake, is purple-brown granule, which is the residue left after the fruit of Theaceae is pressed for oil. Tea meal contains saponins, also known as saponins, which is a hemolytic toxin that can dissolve the red blood cells of fish, so it can kill various wild fish, snails, mussels, frog eggs, tadpoles and some aquatic insects. Diosgenin is easy to dissolve in alkaline water, and a small amount of lime water is added when it is used for better efficacy. Because of its high protein content, tea meal is also a kind of high efficiency cake fertilizer, which can increase fertilizer in ponds with less silt and poor sediment.
The use of tea meal as a pond-clearing drug has a more unique effect than other drugs. First, tea meal is a green drug, non-toxic residue, no impact on the human body, and safe to use. Second, it does not kill aquatic plants and has the effect of promoting the growth of aquatic plants. Third, the larvae of prawns and crabs have no side effects and can promote the shelling of shrimp and crabs. Fourth, it can increase the fertilizer effect, and the emergence rate of shrimp fry and young crab can be significantly improved when it is used in the pond where shrimp fry and young crab are bred. Usage and dosage of tea meal: clear the pond with water, with a water depth of 30ml / mu and 35kg / mu. In order to improve the efficacy, 1.5 kg of salt and 1.5 kg of quicklime are added every 50 kg of tea meal. The tea meal must be soaked for 24 hours before it can be sprinkled in the whole pool.
