The growth of colorful peppers requires sufficient nutrient conditions. The production of 1000 kg of colorful pepper requires 4.2 kg of pure nitrogen, 1.1 kg of phosphorus pentoxide, and 6.5 kg of potassium oxide. At the same time, an appropriate amount of calcium fertilizer is needed. Before planting, apply 4,500 kg of organic fertilizer per acre, 150 kg of bio-organic compound fertilizer, 50 kg of urea, 25 kg of superphosphate, 50 kg of potassium sulfate, and 100 kg of calcium fertilizer. When the seedlings are over and the first ear is grown to the size of the walnut, the first top dressing is carried out, applying 5 kg of pure nitrogen per acre and 6 kg of potassium oxide. When entering the first ear fruit (men pepper) is about to be harvested, the second layer of fruit (for pepper) and the third layer of fruit continue to expand and the third layer of fruit is falling and fruit set, for the peak of fertilizer demand, should be reapplied 2 The second top dressing, applying 6 kg of pure nitrogen per mu and 7-8 kg of potassium oxide.
