The Latest High-Yield Fertilization Techniques and Methods Tutorial for Bell Peppers

The bell pepper is a popular market vegetable; it is nutritious, rich in vitamins, and lacks the pungency of chili peppers, so it can be eaten as an everyday vegetable. For those growing bell peppers, fertilization is very important, so how should bell peppers be fertilized to achieve high yields? Let's take a look.

1. Nutrient Requirements

The bell pepper has a long growing period, but its root system is not well developed and penetrates shallowly into the soil; it is neither drought-tolerant nor waterlogging-tolerant, and its fertilizer demand is far greater than that of tomatoes and eggplants, while its 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, and in the 30-40 days before harvest, absorption accounts for 60%-80% of the total absorption, until at harvest the absorption amount roughly stabilizes.

2. Seedling Fertilizer

Since the bell pepper has 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, no fertilization is generally needed. If the seedlings grow slowly, with narrow, elongated 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

The bell pepper has a long growing period and an underdeveloped root system, so to ensure that the seedlings have sufficient vegetative growth after transplanting and bear more fruit later, using sufficient organic fertilizer as base fertilizer is essential. The organic fertilizer used as base fertilizer is best fully decomposed barnyard manure, and the amount used should be large. Generally, during spring plowing, 3000-3500 kg per mu is applied; after leveling and harrowing, beds are made, then a layer of 1000-1500 kg of organic fertilizer is spread, and after raking level, transplanting is done. This layered fertilization is greatly beneficial for promoting seedling growth and meeting nutrient needs in the later stage, laying a solid foundation for a high yield of bell peppers.

4. Topdressing

Bell peppers generally need topdressing three times. The first is after the seedlings have recovered, when a furrow is opened near the plants, high-quality organic fertilizer is spread in the furrow, then covered with soil, and watering is appropriately controlled to encourage sturdy seedling growth; the second topdressing is during the full fruiting period, which is when bell peppers have their greatest fertilizer demand, so it should be applied heavily, generally 2000 kg of 15% human excrement and urine per mu is appropriate, or an appropriate amount of chemical fertilizer can be applied instead; at the same time, this is also the rainy season, so drainage should be attended to in order to avoid root rot and leaf drop; the third fertilization should be during the middle and late harvest period, when the rainy season has passed, sunlight is abundant, temperatures drop, and the difference between day and night temperatures is large, which suits growth and development under these conditions, so human excrement and urine or nitrogen fertilizer should be applied once every 8-10 days, with the specific amount depending on the plant's growth.
