Embodiment 1
[0062] The experimental site is the Peony Resource Garden of the Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences. On October 1, 2011, selected 20 4-5 year-old peony varieties'Paeonia suffruticosa'mulanhuanzhuang' (Paeonia suffruticosa'mulanhuanzhuang') with strong growth of 8-10 branches and strong growth of branches. Seedlings emerge at o'clock (after the sun has diminished) to prevent water from evaporating too quickly. Prune the root system after emergence, remove the diseased roots and rotten roots, keep the root length about 38cm, put the plant in a cool place, and dry it naturally for 3d (days) under cool conditions. The pruned plants were planted in pots with a height of 45 cm and a diameter of 36 cm on October 3. Fill the matrix (peat charcoal: perlite = 2:1 (volume ratio)) and immediately pour thoroughly.
[0063] On October 15th, the potted plants were moved to a 4℃ cold storage for low temperature treatment. On November 1, the cold stora...
Embodiment 2 to 7
[0065] Except for the contents listed in Table 1, cultivation was carried out in the same manner as in Example 1.
[0066] Table 1 The parameter values and the measurement results of the measured parameters of the "Mulan Huanzhuang" variety for New Year's Day promotion treatment
[0067]
[0068] From the results in Table 1, it can be seen that potting and entering the greenhouse at an appropriate time can help promote the opening of peony flowers during New Year's Day (Example 1). The time for receiving low temperature in the cold storage is short, and the dormancy of peony mixed bud buds cannot be released in time. During the New Year's Day, the germination rate and flower formation rate may not fully meet the flower formation requirements. The cold storage is occupied for a long time (Example 2). Although the flower formation rate and germination rate are high, the cold storage is occupied for a long time and the consumption cost is too large. The warming time in the greenhou...
Embodiment 8-14
[0070] Except for the content listed in Table 2 and using the "Fugui Mantang" variety instead of the "Mulan Huanzhuang" variety, the same procedure as in Example 1 was performed.
