本试验采用温度、预先冷冻和预先洗涤等方法处理茼蒿种子。结果表明:茼蒿种子能够萌发的温度范围为10~30℃,最适宜萌发温度为25℃;预先冲洗有利于茼蒿种子快速、整齐地发芽,最佳冲洗时间为8h;冷冻处理对种子萌发率影响不大,只是明显提高了种子的发芽指数,其中10℃冷冻处理4d提高种子的发芽指数最大。 This experiment uses temperature, pre-freezing and pre-washing method to deal with the seeds of Artemisia selengensis. The results showed that the germination temperature was 10 ~ 30 ℃ and the optimum germination temperature was 25 ℃. The pre-rinsing was conducive to quick and neat germination of seeds of Artemisia selengensis. The best irrigation time was 8h. The effect of freezing treatment on germination rate Not only increased the germination index of the seeds obviously, but the germination index of the seeds increased with the freezing treatment at 10 ℃ for 4 days.
