青椒属茄科,常异交作物,假二杈分枝,发芽所需要的温度范围为10—35℃,最适宜温度为20—30℃,,低于20℃发芽很不整齐。生育适温为25℃,低于15℃生育缓慢,而且发生生理障碍,高于30℃则植株不能正常发育。发芽后30天开始花芽分化,但由于青椒开花受温度的影响较大,虽然花芽分化较早,开花时间却较迟,一般早熟种播种后约60天才开第一朵花,晚熟种要在播种后90天才开第一朵花。第一分枝的节位根据品种不同有所变化,大致在7—16个叶片之间,分枝节位越早越早熟。青椒需水量并不算高,但由于根群不发达,主要根群分布不深,必须经常保持土壤湿润。它既不耐旱,也不耐涝,淹水数小
Green peppers are Solanaceae, often outcrossed crops, leave two branches, germination temperature range required for the 10-35 ℃, the most suitable temperature is 20-30 ℃, less than 20 ℃ germination is very irregular. Fertility temperature is 25 ℃, less than 15 ℃ slow birth, and physiological disorders, higher than 30 ℃ plants can not normally develop. However, since the flowering of peppers is more affected by the temperature, the flower bud differentiation is earlier and the flowering time is later. Generally, the first mature flower is about 60 days after sowing, and the late-mature species is sown After 90 days to open the first flower. The first branch of the node varies according to different varieties, roughly between 7-16 leaves, the sooner the more premature branches of the node. Green pepper water demand is not high, but due to underdeveloped root groups, the main root distribution is not deep, we must always keep the soil moist. It neither drought nor waterlogging, flooding a few small
