The production of 1000 kg of tomatoes requires 3.85 kg of pure nitrogen, 1.2 kg of phosphorus pentoxide, and 4.4 kg of potassium chloride. According to the calculation of 5000 kg per mu, 5,000 kg of high-quality farmyard manure and 50 kg of phosphate fertilizer are applied before the planting. When the first ear is swollen to the size of egg yolk, the first top dressing should be carried out, and the pure nitrogen 18-2 topdressing kg, the phosphate fertilizer 15-16 kg, and the potassium fertilizer 16-17 kg should be applied. The second, third and fourth ear fruits are swollen. When the size of egg yolk is small, it should be topdressed in time. In this case, the amount of fertilizer needs to be large, and the amount of topdressing should be increased appropriately. Each top dressing should be combined with watering. It is also possible to use a 0.35% chemical fertilizer in combination with a disease-preventing drug or a mixture of growth hormones such as Tianfengsu and Shuofeng 481 for foliar application.
