Detailed Explanation of Key Fertilization Techniques for High-Yield Peppers

Peppers are the most common vegetable in our daily lives and one of our commonly used seasonings. Peppers not only have high edible value but can also be grown as ornamental plants. When growing peppers, fertilization is an important step that affects both the yield and quality of the peppers. So how should peppers be fertilized to achieve high yields? Let's find out together.

1. Seedling Raising Substrate

When raising pepper seedlings, it is best to dig soil from plots where solanaceous vegetables and tobacco have never been grown. You can use topsoil from plots where onions or garlic, celery, or grain crops have been grown, dig it out, and after sun-drying or crushing and sifting, obtain fine soil. Fully decomposed barnyard manure should likewise be crushed and sifted for later use, then mixed with the soil at a ratio of 1:3. Then, for every 1000 kg of cultivation soil, add 1 kg of calcium phosphate, 20 kg of plant ash, and 0.5 kg of diammonium phosphate. After mixing evenly, it can be used as a seedling raising substrate.

2. Applying Sufficient Base Fertilizer

Before the seedlings are transplanted to the planting field, in order to promote seedling growth, sufficient base fertilizer is generally applied in the field. This is one of the effective measures for obtaining high yields of peppers. The base fertilizer should be mainly organic fertilizer, and the organic fertilizer must be fully decomposed to avoid introducing pathogens and insect eggs, which could cause pests and diseases in the seedlings. Application is carried out in combination with land preparation and plowing. Generally, 4000-5000 kg of decomposed farmyard manure is broadcast or applied in furrows per mu, together with 30 kg of diammonium phosphate or urea and 100 kg of plant ash, which can continuously provide nutrients for the seedlings.

3. Reasonable Topdressing

Peppers have a relatively large nutrient demand during the growing period. In order to give them enough nutrients to flower and set fruit, topdressing is generally needed 2-3 times during the growing period. The first time is during the young fruit stage, when 1500 kg of human excrement and urine can be applied per mu. It is recommended to apply topdressing before the rainy season. If there is no rain, water promptly after topdressing, which can speed up nutrient absorption. The second time is during the full fruit stage, when 10-15 kg of ternary compound fertilizer is applied per mu, also followed by watering. This can provide phosphorus and potassium fertilizer to the plants and has an obvious yield-increasing effect. The third time is before harvest, when topdressing should be applied vigorously and frequently. Basically, human excrement and urine fertilizer should be applied once every week, preferably in the early morning or evening.

4. Foliar Feeding

Foliar feeding generally refers to spraying fertilizer on the leaves. Its advantages are a small dosage, high absorption rate, and quick effect. It can also enhance the plant's photosynthesis and chlorophyll content, which is beneficial to the accumulation of organic matter in the plant and effectively prevents flower and fruit drop. It can generally increase yield by about 10%-20%. Specifically, spraying a low-concentration borax aqueous solution 1-2 times during the flowering period can improve the fruit-setting rate. In the later growth stage, spraying a low-concentration potassium dihydrogen phosphate solution multiple times has an excellent yield-increasing effect. In addition, note that foliar fertilizer spraying is prohibited half a month before harvest.
