Chili peppers are a low-calorie, high-nutrient vegetable . Fertilization is crucial for high yield and quality when growing chili peppers . So, what is the best fertilizer for chili peppers? Let's find out.
1. Organic fertilizer
Organic fertilizer is a natural fertilizer that can improve soil texture and fertility, enhance soil water retention and aeration, promote root growth in chili peppers, and facilitate nutrient absorption. When using organic fertilizer for chili peppers, it is crucial that it be fully decomposed. Applying undecomposed organic fertilizer to the soil will continue to ferment, generating high temperatures that can easily burn the plant's roots.
2. Compound fertilizer
Compound fertilizer is a comprehensive fertilizer that provides the essential nutrients needed for chili pepper growth, such as nitrogen, phosphorus, and potassium. Nitrogen promotes the development of the plant's stems and leaves; insufficient nitrogen in chili pepper plants will result in weak growth, yellowing leaves, and premature aging. Phosphorus promotes flowering and root development, while potassium promotes fruit enlargement.
3. Foliar fertilizer
In the later stages of growth, the root system of chili pepper plants gradually ages, which reduces nutrient absorption and decreases fruit production and fruit enlargement. Foliar fertilization, on the other hand, is characterized by rapid absorption, strong effect, and low dosage, and can effectively overcome the problem of insufficient nutrients in the later stages of crop growth, thus greatly extending the harvest period of chili peppers.
4. Diammonium phosphate
Diammonium phosphate is rich in phosphorus and nitrogen, which can promote the development of pepper roots and growing points, and improve the plant's resistance to adverse conditions. Phosphorus is important for pepper fruit development and formation, and it can also promote root growth and improve the plant's disease resistance.
5. Potassium sulfate
Potassium sulfate is rich in potassium, which can promote fruit growth and increase yield, while also enhancing the disease resistance of chili peppers. Potassium can promote fruit development and improve the plant's stress resistance, as well as improve the quality and taste of chili peppers.
