Detailed Explanation of Key Points of High-Yield Fertilization Techniques for Bell Peppers

Bell pepper is a popular market vegetable. It is rich in nutrients and vitamins, and it lacks the spicy taste of chili peppers, so it can be eaten as an everyday vegetable. For those who grow bell peppers, fertilization is very important, so how should bell peppers be fertilized to achieve high yields? Let's take a look.

1. Fertilizer Requirements

Bell peppers have a long growing period, but their root system is not well developed and penetrates relatively shallowly into the soil. They are neither drought-tolerant nor waterlogging-tolerant, and their fertilizer requirement is far greater than that of tomatoes and eggplants, while their tolerance for fertilizer is strong. Generally, for every 1000 kg of bell peppers produced, 4.91 kg of nitrogen, 1.19 kg of phosphorus, and 6.02 kg of potassium need to be absorbed from the soil, with an absorption ratio of 5:1:6. The absorption of nutrient elements increases with the growth and development of the vegetable. From fruit enlargement to the harvest period, nutrient absorption increases rapidly. In the 30-40 days before harvest, the absorption amount accounts for 60%-80% of the total absorption, and until harvest, the absorption amount remains roughly stable.

2. Seedling Fertilizer

Because bell peppers have a relatively long growing period, it is advisable to choose soil rich in humus as the seedbed. When nutrition is sufficient during the seedling stage, fertilization is generally not needed. If the seedlings grow slowly, have narrow and long leaves, and thin stems, a small amount of urea can be applied with water half a month before transplanting to promote seedling growth.

3. Base Fertilizer

Bell peppers have a long growing period and a poorly developed root system, so in order to ensure that the seedlings have sufficient vegetative growth after transplanting and bear more fruit later, it is essential to use sufficient organic fertilizer as base fertilizer. The organic fertilizer used as base fertilizer is best fully decomposed manure, and the amount used should be large. Generally, 3000-3500 kg per mu is applied during spring plowing. After leveling and raking, make beds, then spread another 1000-1500 kg of organic fertilizer, rake level, and transplant. This layered fertilization is very beneficial for promoting seedling growth and meeting nutrient needs later, laying a solid foundation for high bell pepper yields.

4. Topdressing

Bell peppers generally need topdressing three times. The first is after the seedlings have revived; open a furrow near the plants, spread high-quality organic fertilizer in the furrow, then cover with soil, and control watering appropriately to promote seedling establishment. The second topdressing is during the full fruit period, which is the period of greatest fertilizer demand for bell peppers, so it should be applied heavily. Generally, 2000 kg per mu of 15% human manure and urine is suitable, or an appropriate amount of chemical fertilizer can also be applied. At the same time, this is also the rainy season, so attention should be paid to drainage to avoid root rot and leaf drop. The third fertilization should be done in the middle and late harvest stages. By then the rainy season has passed, sunlight is sufficient, temperatures have dropped, and the temperature difference between day and night is large, which is suitable for growth and development. Human manure and urine or nitrogen fertilizer should be applied once every 8-10 days, with the specific amount depending on plant growth.
