[0058] Examples 1 to 15

[0059] The experimental site is the Peony Resource Garden of the Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences. On August 10, 2011, 20 4-5 year-old autumn-haired peony varieties'paeonia suffruticosa'cangzhihong' (paeonia suffruticosa'cangzhihong') with 8-10 strong branches were selected for defoliation. After defoliation, the water was controlled for 10 days, and then the lateral buds were wiped off, leaving only the one bud closest to the top (generally the top bud or the first bud), and 10 plants were used in each example. On August 25th, the retained buds were subjected to the first colchicine (the active reagent GA 3 , Auxin and Zeatin are all analytically pure, purchased from Beijing Chemical Reagent Company, the concentration is shown in Table 1).

[0060] After the peony buds enter the transparent period, the seedlings will emerge at 16-17 o'clock in the afternoon (after the sun is weakened) to prevent the water from...

[0065] The experimental site is the Peony Resource Garden of the Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences. On August 10, 2011, 20 4-5 year-old autumn-haired peony varieties'paeonia suffruticosa'cangzhihong' (paeonia suffruticosa'cangzhihong') with 8-10 strong branches were selected for defoliation. After defoliation, control the water for 10 days, then erase the side buds, leaving only the bud closest to the top (generally the top bud or the first bud). On August 25th, the retained buds were subjected to the first colchicine (the active reagent GA 3 , Auxin and Zeatin are all analytically pure, purchased from Beijing Chemical Reagent Company, GA 3 , Auxin and zeatin weight ratio is 8:1:1, the same below) smearing treatment, the concentration of the fall hair element used for the first smear (that is, GA 3 The sum of the concentration of auxin and zeatin) is 1000mg / L. After that, two smears were carried out in sequence ever...

[0070]

[0071] It can be seen from the results of Table 1 and Table 2 that the present invention can break the dormancy of autumn peony buds and make them germinate through the defoliation treatment, but it cannot promote all the mixed buds to flower. For autumn peony, the defoliation treatment combined with the gradually increasing concentration of colchicin application treatment makes the autumn peony have significant effects in breaking dormancy, increasing flower formation 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.
