How to fertilize ornamental peppers? A detailed guide to the correct fertilization method
Ornamental pepper, also known as clustered pepper and ornamental chili, is a variety of chili. Its fruits cluster at the top of the branches, and fruits on the same plant come in many colors such as yellow, red, purple, and green. Ornamental pepper needs sufficient nutrients for growth, so fertilization is essential. So how should ornamental pepper be fertilized? Let's take a look together.
1. Nutrient requirements
Ornamental pepper has relatively high nutrient requirements. On average, for every 1000 kg of fruit produced, it consumes 4.2 kg of pure nitrogen, 1.1 kg of phosphorus pentoxide, and 6.5 kg of potassium oxide, and it also needs an appropriate amount of calcium fertilizer and pepper stalk-strengthening agent. Therefore, when planting, fertilization should focus mainly on phosphorus and potassium fertilizers. In the early growth stage, nitrogen fertilizer should be the main focus to promote plant growth and produce more branches, laying the foundation for fruiting. In the later stage, potassium fertilizer should be the main focus to promote fruit expansion and improve yield and quality.
2. Base fertilizer
Before transplanting, the soil needs to be prepared and fertilized to ensure the soil is loose and breathable, creating a suitable environment for the growth and development of the seedling roots after transplanting. Combined with soil preparation, apply 4500 kg of organic fertilizer, 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 per mu. Mix them evenly and apply, then plow them into the soil. It should be noted that direct contact between roots and fertilizer should be avoided to prevent root burn.
3. Seedling-stabilizing fertilizer
After the seedling stage, when the first cluster grows to the size of a walnut, carry out the first topdressing, applying 5 kg of pure nitrogen and 6 kg of potassium oxide per mu. At this time, the plant's vegetative growth and reproductive growth advance together, so fertilization should focus mainly on nitrogen and potassium fertilizers to promote branch and leaf growth and fruit expansion, which can significantly increase yield.
4. Harvest fertilizer
When the first cluster of fruits is about to be harvested, the second layer of fruits and the third layer of fruits continue to expand, and the third layer of fruits is setting fruit after flowering, this is the peak period of nutrient demand for the plant. The second fertilization should be applied heavily, with 6 kg of pure nitrogen and 7-8 kg of potassium oxide per mu. After that, carry out the third fertilization half a month later, with the same amount as the second. After 15-20 days, apply the fourth fertilizer, with the same amount as the first.
