How to clean up the Sichuan police in the fish pond

It is best to kill the moss in the fish pond before stocking the fry. For the fish pond after clearing the pond, there is 7 ~ 10 cm deep water in the pond, and several small ponds are dug at the bottom of the pond. Take 50 ~ 75 kilograms of quicklime per mu of water surface, sprinkle it in a small pond and melt it with water. Sprinkle around immediately before cooling. For fish ponds with pool cleaning water, the dosage can be calculated by using quicklime 125 ~ 150 kg per mu of water depth. You can put the quicklime into the laundry list and move the laundry list by boat (or other tools) to make the quicklime evenly dispersed in the water in the fish pond. In addition, plant ash can sprinkle 50 ~ 100 kg of water on the moss, so that the moss will die without sunlight.

If there are fry or adult fish in the fish pond, you can kill moss with prometryne. When the average water depth per mu is1.5 ~ 2kg, it will be mixed with fine soil according to the ratio of 1: 100 and spread evenly in the pond. Then, on a sunny morning, when the average water depth per mu is 1m, sprinkle more moss in places rich in moss, and the moss can be killed in two days. In addition, pine leaves can also be soaked, ground, stirred with water to form slurry, and 25 kilograms of slurry can be splashed every mu of water every day for 2-3 days to kill moss.
