使牡丹、芍药在夏季开花,传统技术是在发芽前将牡丹、芍药种苗从大田起出,放入冷库低温贮存,然后适时取出,使其在人工气候室于预定花期之日盛开。这种方法虽然能使牡丹、芍药应时开花,但开花质量与自然花期相比有很大差距。2006年4月中、下旬,菏泽市牡丹研究所通过精心准备,把即将含苞待放的牡丹、芍药从大田起出上盆,放入冷库贮存,然后适时取出,花期一直持续到了7月下旬,且开花质量完全可以与大田自然开花相媲美。

Although this method can make peony, peony flowering should be, but the flowering quality compared with the natural flowering is a big gap. April 2006, late, Heze City Peony Institute carefully prepared by the upcoming budding peony, peony from the field started on the pot, placed in cold storage, and then removed in due course, the flowering continued until late in July, And flowering quality can be comparable with natural flowering field.
