Pepper full fertilization program

In China, peppers are grown all over the country, from north to south. Due to regional differences, different places have different preferences for the characteristics of pepper varieties. These preferences include the shape, spiciness, color and flesh thickness of the peppers, so pepper varieties in different regions vary accordingly. However, while variety selection may vary from place to place, pepper fertilization techniques are similar across the country. Let’s learn about the complete fertilization plan for peppers.

1. Fertilizer requirements of peppers

Division of the growing period: The growing period of pepper is usually divided into the germination period, seedling period, flowering and fruiting period, and fruiting period.

Fertilizer requirement ratio: The pepper's requirement ratio for nitrogen (N), phosphorus (P), and potassium (K) during the entire growing period is roughly 1:0.5:1. To produce 1000kg of peppers, approximately 3.5-5.4kg of nitrogen fertilizer, 0.8-1.3kg of phosphorus pentoxide, and 5.5-7.2kg of potassium oxide are required.

Characteristics of fertilizer requirements at different stages:

Germination period: Nutrient requirement accounts for 5% of the total absorption.

Seedling stage: As growth accelerates, nutrient requirements increase to 11%.

Flowering and fruiting period: Fertilizer requirement accounts for 34% of the total, with nitrogen fertilizer absorption being the highest.

Fruiting period: Nutrient absorption accounts for 50% of the total, and the demand for phosphorus and potassium fertilizers increases.

2. Field planting fertilization plan

Base fertilizer: Use balanced compound fertilizer as the main method and avoid using chlorine-containing fertilizers to meet the nutritional needs of peppers throughout their entire growth cycle.

Seedling fertilizer: Mainly high-nitrogen and high-phosphorus compound fertilizer to meet the nutritional needs of peppers from sowing to transplanting.

top dressing:

After seedlings have grown, apply 8-11kg of Miaoliwang to meet nitrogen needs.

Seedling stage: Flush with 10-15kg of medium-nitrogen and high-potassium water-soluble fertilizer , combined with medium-element water-soluble fertilizer.

Before flowering and fruiting: apply 10-15kg of balanced compound fertilizer, such as 17-17-17 (sulfur-based).

During the peak flowering and fruiting period: Apply 5-8 kg of pepper-specific fertilizer (14-5-26) every 15-20 days, and gradually reduce the dosage.

Foliar topdressing: During the flowering and fruiting period, spray water-soluble fertilizers and potassium dihydrogen phosphate to increase the number of fruits and the quality of the fruits.

3. Key Management Technologies

Select good varieties: Select suitable high-yield and high-quality varieties based on market demand, yield, disease resistance and stress resistance.

Intertillage and weeding: In the middle growth period of pepper, timely break the film and carry out intertillage to promote the deep growth of the root system and prevent premature aging.

Pest and disease control: Take appropriate prevention and control measures in a timely manner against diseases such as epidemics, wilt, and viral diseases. For major insect pests, such as aphids, cutworms, etc., use appropriate pesticides for prevention and control.

Key points for field management: Reasonably control light, water and fertilizer conditions, and pay attention to the characteristics of peppers: they like light but are afraid of strong light, like moisture but are afraid of waterlogging, and like fertilizer but are afraid of fertilizer burn.

In short, before planting peppers, understanding the fertilizer requirements and fertilization methods of peppers can effectively improve the yield and quality of peppers and achieve the goals of high yield, high quality and high efficiency in pepper planting .
