Embodiment 1
[0027] Embodiment 1: the basic biological characteristics of seedlings before planting
[0028] The biological characteristics of the 4-year-old 'Fengdan' peony are as follows: figure 1 As shown in a: the stalk is black-gray, the number of main and lateral roots can reach as many as 9, the thickness of the main root and branches is more than 10mm, and the branch length reaches 34.5cm. The branches of the stalk differentiate and bud, and each plant is about There are 6 differentiated buds, and the buds are full ( figure 1 shown in the inset of a). From the root to the top, the buds develop gradually and mature, which is reflected in the gradual enlargement of the buds and the gradual increase of the distance between adjacent buds. Before planting, the roots need to be pruned to remove broken roots, rotten roots and cracked roots, which account for about 24% of the strains, indicating that when digging seedlings, the fleshy root system is more likely to be damaged and break or...
Embodiment 2
[0029] Embodiment 2: Transplantation of peony for oil
[0030] (1) According to the following criteria, screen the ramet seedlings of 'Fengdan' peonies for 4-year oil production: actual branch length ≥ 10cm; branch thickness ≥ 0.6cm; taproot number ≥ 5; taproot length ≥ 20cm; taproot thickness ≥ 0.6cm ; The buds are full and plump.
[0031] (2) Plant ramet seedlings from October to December. Seedlings that cannot be planted in time should be covered, or protective measures such as sand storage and soil covering should be implemented.
[0032] (3) Prune the roots of the transplanted seedlings, keep the same length of the main root and the main lateral root on the same plant, and keep the length of the root at 5-20cm.
[0033] (4) Soak the whole plant of the seedlings and disinfect them with 80% carbendazim 1000 times solution for 10 minutes, then soak the roots with 1 / 500 (m / v) indole acetic acid for 5 seconds to promote rooting of the seedlings, remove and drain and plant.

Embodiment 3
[0036] Example 3: Effects of Different Planting Periods on the Biological Characters of Oil Peony
[0037] In order to study the effect of planting time on the growth and yield of peony, 4-year-old 'Fengdan' seedlings were introduced from Heze, Shandong in October 2015, and were planted in the experimental field of Wuhan Forestry and Fruit Research Institute in 5 stages, respectively: 2015.10.20 (CK), 2015.11.10(T1), 2015.11.25(T2), 2015.12.10(T3), 2015.12.25(T4). Carry out transplant operation according to the step of embodiment 2, table 1 shows: first year after planting (2016) finds that the nursery stock of T1 time planting compares with contrast, its growth and fruit pod formation are not affected, and single fruit pod seed number is also not affected. not significantly reduced. As the planting time continues to move back, the seedlings will gradually have the phenomenon of leaf dysplasia, the leaves will become smaller, and the aspect ratio of the leaves will gradually ...
