The growth of Capsicum annuum requires sufficient nutrient conditions. The production of 1000kg of colorful pepper requires 4.2kg of pure nitrogen, 1.2kg of phosphorus pentoxide, and 6.5kg of potassium oxide. At the same time, it also needs an appropriate amount of calcium fertilizer. Before planting, apply organic fertilizer 4500kg per 667 square meters, bio-organic compound fertilizer 150kg, urea 50kg, superphosphate 25kg, potassium sulfate 50kg, calcium fertilizer 100kg. When the seedlings are over and the first ear grows to the size of the walnut, the first topdressing is performed, applying 5 kg of pure nitrogen per 667 square meters, and 6 kg of potassium oxide. When entering the first ear fruit (Jian 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 for fruit setting, it is the peak period of requirement fertilizer and should be reused. The top dressing was applied with 6 kg of pure nitrogen per 667 square meters and 7-8 kg of potassium oxide. The third topdressing was performed about two weeks later and the amount of fertilizer was the same as the second. After 15-20 days, the 4th top dressing was performed with the same amount of fertilizer applied for the first time. 3 Layers Earloop Disposable Face Mask Bacteria Protection Face Mask,3 Ply Breathable Face Masks,3D Stereo Face Mask,3 Layers Earloop Disposable Face Mask Dongguan Keyutai Mask Co., Ltd. , https://www.maskkytai.com
