It is an alkaline fertilizer and is a kind of high-quality quick-acting potassium fertilizer. Its application effect is better than that of chemical potassium fertilizer. The application of plant ash to fish ponds can not only regulate and improve the water quality of fish ponds, but also prevent fish diseases and promote fish growth. The pH of the water required to regulate the growth of pH is generally 7.5~8.5. The test shows that the fish ponds with unclear silt generally have a pH of about 7 or so, and the fish ponds that have been cleared of silt are about 7.3~7.5, which can not meet the growth needs of the fish. The fish pond with a water depth of 1.5 meters can be raised to a pH of 7.5 to 8.5. For every 667 square meters of ponds, 100-180 kilograms of wood ash should be applied. Fertilizing water quality fish ponds often apply grass ash, which can increase the content of potassium, phosphorus, calcium, magnesium and other elements in water, promote the reproduction of plankton, and provide sufficient natural bait for fish growth. At the same time, the plant ash also contains many trace elements. The prevention and treatment of fish disease wood ash has a bactericidal effect and can effectively kill various pathogens on fish body. The application of grass ash can not only disinfect the fish pond but also purify the water. The specific use method is as follows: dry ash should be taken from the stove (not to be drenched with rain), immersed in a bucket or a tank for 4-6 hours, and splashed with the whole pool of leaching solution. Do not use dry ash directly. When applying ash, it is not possible to apply human and manure at the same time.
