In addition to applying nitrogen, phosphorus, and potassium fertilizers, cherry tomatoes should be supplemented with calcium and boron fertilizers. The production of 1,000 kilograms of cherry tomatoes requires 3.85 kilograms of pure nitrogen, 1.15 kilograms of phosphorus pentoxide, and 4.44 kilograms of potassium oxide. Before planting, 5000 kg of organic fertilizer was applied per mu, 200 kg of bio-organic compound fertilizer, 50 kg of urea, 30-50 kg of superphosphate, 40 kg of potassium sulfate, 100 kg of calcium fertilizer, and 1.5 kg of borax.
Generally when the first fruit begins to swell, it can be topdressed for the first time, with 5 kg of pure nitrogen per acre and 6 kg of potassium oxide. The second time dressing is the first time the fruit is about to be harvested. When the second fruit is enlarged, 5 kg of pure nitrogen per acre and 6-7 kg of potassium oxide are applied. The third dressing will be harvested in the second ear. When the third ear is enlarged, 4 kg of pure nitrogen and 5 to 6 kg of potassium oxide will be applied per mu.
