一、主要生理特性: 青椒的发芽适宜温度为25～30℃,低于20℃发芽不整齐。生育适温为25℃,低于15℃生育缓慢。花芽分化在发芽后30天即开始,一般早熟种在播种后60天才开第一朵花,晚熟种要在播种后90天才开第一朵花,第一分枝的节位一般在7～16片叶之间,分枝节位越低越早熟。
First, the main physiological characteristics: the optimum temperature for the germination of green pepper is 25 ~ 30 ℃, less than 20 ℃ germination irregular. Fertility temperature is 25 ℃, less than 15 ℃ fertility is slow. Flower bud differentiation began 30 days after germination, the general precocious species in the first 60 days after sowing to open the first flower, 90 days after sowing to open the first flower, the first branch of the node is generally 7 to 16 Between the leaves, the lower the degree of branching more precocious.
