The latest course of fertilization techniques for High yield of Sweet Pepper

Sweet peppers are a popular market because they are nutrient-rich, vitamin-rich, and not as spicy as peppers, and can be eaten as a daily vegetable. For friends who grow sweet peppers, fertilization of sweet peppers is very important, so how can sweet peppers be fertilized to obtain high yield? Let's take a look.

1, need fertilizer characteristics

Sweet pepper has a long growth period, but its roots are underdeveloped, its soil is shallow, it is not drought-tolerant and not hard-working, its fertilizer requirement is much greater than that of tomato and eggplant, and its fertility tolerance is strong. Generally, for every 1000 kg of sweet pepper produced, it needs to absorb 4.91 kg of nitrogen, 1.19 kg of phosphorus and 6.02 kg of potassium from the soil, and their absorption ratio is 5:1:6. Nutrient uptake increased rapidly from fruit expansion to harvest, accounting for 60%-80% of the total uptake 30-40 days before harvest, and stabilized until harvest.

2, seedling fertilizer

Due to the long growth period of sweet pepper, it is advisable to choose soil rich in humus as seedbed. When the nutrition is sufficient in the seedling stage, there is generally no need to apply fertilizer. If the seedlings grow slowly, the leaves are narrow, and the stems are lean, a small amount of urea can be applied with water half a month before planting to promote seedling growth.

3. Base fertilizer

Sweet pepper has a long growth period and underdeveloped roots, so in order to ensure sufficient nutritional growth and late fruit of seedlings after planting, it is essential to use sufficient organic fertilizer as base fertilizer. The organic fertilizer used as base fertilizer had better be fully decomposed manure, and the dosage should be large. Generally, 3000-3500 kg per mu should be applied along with spring ploughing. After shaping and leveling, the bed should be made, and a layer of 1000-1500 kg organic fertilizer should be spread. After leveling, planting should be done. Such layered fertilization is beneficial to promoting seedling growth and nutrient demand in later stage, laying a solid foundation for high yield of sweet pepper.

4. Topdressing

Sweet pepper generally needs topdressing three times, once after the seedling is slowed down, ditch topdressing near the plant, sprinkle high-quality organic fertilizer in the ditch, cover the soil, properly control watering, so as to squat seedlings; The second topdressing is in the full fruit period, which is the period when sweet pepper needs the largest amount of fertilizer, so it is necessary to reapply, generally 15% of human excrement per mu is appropriate, or appropriate amount of chemical fertilizer can also be applied, at the same time it is rainy season, pay attention to drainage, so as not to rot roots and fall leaves; The third fertilization should be in the middle and late harvest chicken heart, when the rainy season has passed, sufficient light, temperature drop, day and night temperature difference, suitable for the growth and development of conditions, should be every 8-10 days 1 time human manure or nitrogen fertilizer, the specific amount of fertilizer depends on plant growth.

The above is the introduction of high-yield fertilization technology for sweet pepper. I hope it can help you. If you want to know more about it, please pay attention to us.
