Sweet pepper, scientific name: Capsicum frutescens L. (syn. C. annuum L.) var.grossum Bailey., Solanaceae Capsicum, a subspecies of sweet berries, annual or perennial herbs. The flesh is thick, crisp and tender and rich in vitamin C.

Sweet peppers evolved from peppers native to the tropical regions of Central and South America in North America. After long-term cultivation and artificial selection, the fruit volume increased, the pulp became thicker, the spicy taste disappeared, and the number of carpels and ovary cavities increased. .

Plants are stout and tall. The leaves are oblong or ovate, 10-13 cm long. Fruit pedicel erect or drooping, fruit large, nearly spherical, cylindrical or oblate spherical, with many longitudinal grooves, top truncated or slightly concave, base truncated and often slightly concave inward, not spicy but slightly sweet or Slightly peppery.

The optimum temperature for seed germination is 15~30°C, the optimum temperature is about 25°C, the optimum temperature for growth is 27~28°C during the day, 18~20°C at night, and the ground temperature is 17~26°C. The requirements for light length and light intensity are not strict, as long as the temperature is suitable, it can be cultivated all year round. Sweet peppers are neither drought tolerant nor waterlogging tolerant, and have strict water requirements. The suitable substrate relative humidity is 60%~70%, and the suitable air relative humidity is 70%~80%.

The optimum temperature for seed germination is 15-30 °C, and the most suitable temperature is 25 °C. At this temperature, seedlings can be produced in 3-5 days; through low-temperature exercise, sweet pepper seedlings can resist the lowest low temperature of 0 °C in a short time (within 48 hours). ; The maximum temperature is 30 ℃, and the flower organs are not fully developed or the stigma is dry and cannot be fertilized and the flowers will drop when the temperature is higher than 30 ℃. The minimum temperature during the flowering period is 10°C, otherwise it cannot be fertilized; the optimum temperature for fruit development and color change is 20-30°C; sweet pepper colonization requires a stable ground temperature of 10°C before it can be carried out.
