Feed adult fish with 300ppm concentration of rare earths, about 10 days before grass cutting, evenly sprayed on grass, generally 50 kg per mu. It can increase the yield of fresh grass by 7% Mel 9%, and at the same time reduce the loss of rare earths due to water dissolution. You can also use 2 packets of rare earth additives for fish per mu on the day of mowing, spray them on the grass, wait for the water to dry, and then cut them down and feed them. You can also first cut the grass and let the sun bask in it, then add a pack of rare earth additives to fish with 40 grams of rare earth, spray 20 kilograms of water, spray on 300 Mel 400 kilograms of green feed, and then feed it.
