1 When organic fertilizers are used, both solid and liquid fertilizers must be fermented before application, otherwise they may cause damage to the root system, but also emit strong odors and attract fly maggots, which will hinder the environment. 2 When fertilizing, it is best to use organic fertilizers such as oil mash, horseshoe, etc., and fertilizers such as urea, ammonium sulfate, calcium superphosphate, and potassium dihydrogen phosphate, etc., and do not use chemical fertilizers. 3 The amount of fertilization must be strictly controlled, must be "a small number of times" or "bare manure applied." Thin fertilizer usually refers to 8 to 9 parts of water mixed with 2 parts or 1 part of fertilizer solution. 4 before fertilization, basin soil should be slightly dry, it is best to loosen the soil first, and then fertilize, which is more conducive to the absorption of fertilizer by the root, the next day and then watered once to facilitate the accumulation of fertilizer in the topsoil into the soil. 5 Do not spray fertilizer on the leaves when applying fertilizer solution. Pay more attention when dressing herbaceous foliage flowers. To be on the safe side, it is best to spray water once after top dressing and wash the leaves.
