Embodiment 1 to 15

[0059] The experimental site is the Peony Resource Garden of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences. On August 10, 2011, 20 4-5-year-old autumn peony cultivars 'Cangzhihong' (paeonia suffruticosa 'cangzhihong') with 8-10 vigorous branches were selected for defoliation of the whole plant. After defoliation, control water for 10 days, then wipe off the side buds, only keep a bud (generally the top bud or the first bud) closest to the top, and each embodiment adopts 10 plants. On August 25th, the first autumn hair element (the active agent GA contained therein) was carried out on the preserved buds. 3 , auxin and zeatin are all analytically pure, purchased from Beijing Chemical Reagent Company, and the concentration is shown in Table 1) for smearing treatment.

[0060] After the peony buds enter the translucent period, the seedlings should be raised at 16-17 o'clock in the afternoon (after the sun has weakened) to prevent the ...

Embodiment 16

[0065] The experimental site is the Peony Resource Garden of the Vegetable and Flower Research Institute of the Chinese Academy of Agricultural Sciences. On August 10, 2011, 20 4-5-year-old autumn peony cultivars 'Cangzhihong' (paeonia suffruticosa 'cangzhihong') with 8-10 vigorous branches were selected for defoliation of the whole plant. After defoliation, control the water for 10 days, then wipe off the side buds, and only keep the bud closest to the top (usually the top bud or the first bud). On August 25th, the first autumn hair element (the active agent GA contained therein) was carried out on the preserved buds. 3 , auxin and zeatin were all analytically pure, purchased from Beijing Chemical Reagent Company, GA 3 , auxin and zeatin weight ratio is 8:1:1, the same below) smear treatment, the concentration of the autumn hair factor used for the first smear (ie GA 3 , sum of concentration of auxin and zeatin) is 1000mg / L. Smear twice every 3 days thereafter, promptly ca...

Embodiment 17 to 23

[0068] Cultivation was performed in the same manner as in Example 16 except for the contents listed in Table 2.

[0069] Table 2 The parameters used and measured parameters in the experiment of promoting national day flowering with the variety 'Zangzhihong'

[0070]

[0071] As can be seen from the results in Table 1 and Table 2, the present invention can break the dormancy of the buds of the peony in autumn and make it germinate through defoliation treatment, but it cannot impel all the mixed buds to flower. For Qiufa peony, the defoliation treatment combined with the gradually increasing concentration of Qiufasu smear treatment makes Qiufa peony have significant effects in breaking dormancy, increasing flowering rate and shortening the growth period.

Abstract

The invention provides a cultivation method for promoting tree peony to blossom on the National Day. The method comprises the following steps of: 1) selecting plants of autumn-flowering tree peony; 2) performing defoliation treatment on the plants; 3) coating an autumn-flowering agent on buds of the plants subjected to water control treatment, wherein the autumn-flowering agent contains 600mg / L-900mg / L of gibberellin; and 4) moving the plants in pots. According to the method, the shallow-dormancy tree peony is adopted, and the dormancy is removed by comprehensively using the defoliation treatment and the hormone, therefore, the tree peony can blossom on the National Day under the condition that the energy sources are saved; in addition, the plants of the tree peony can be moved in the pots at the appropriate time so as to prevent the plants against flower and leaf withering after being moved in the pots. Compared with the tree peony in an open filed, the pot-cultured tree peony has much more wide application.

Description

technical field [0001] The present invention relates to the cultivation method of plant, more specifically, the present invention relates to the cultivation method of peony. Background technique [0002] Peony, whose scientific name is Paeonia suffruticosa Andr, belongs to the Paeoniaceae (Paeoniaceae) plant of the genus Paeonia. It is native to China and has a history of more than 1,600 years in my country. Hanzhong is the first place in China to artificially cultivate peony.
