元胡属多年生药用植物,以地下块茎入药。元胡较耐寒,生长适温18～20℃,22℃以上叶片出现枯焦点,25℃以上叶片发生青枯乃至植株死亡。后期(4月份)气温回升,容易发生生理青枯和遭病原侵染而引起早衰,造成严重减产甚至无收。因此,春后必须采取防早衰的管理措施。 1.科学排灌元胡生长 Yuanhu is a perennial medicinal plants, medicine to the underground tubers. Yuan Hu is more tolerant to cold and grows at a suitable temperature of 18-20 ℃. Leaves above 22 ℃ appear to be dead spots, and chlorophyll and even plant death occur above 25 ℃. Late (April) temperature rise, prone to physiological sclerosis and pathogen infection caused by premature aging, resulting in serious cuts or even confiscated. Therefore, the spring must take anti-premature aging management measures. 1. Science and Irrigation Yuan Hu growth
