Problems solved by technology

Although this method can inhibit the development of side branches of peony, the application of paclobutrazol is easy to pollute the soil and can remain in the plants for a long time. It is for this reason that paclobutrazol is rarely used in modern agriculture.

Embodiment 1

[0020] This study was carried out with the peony cultivar 'Zifengyu' planted in the peony germplasm resource nursery of the College of Horticulture and Plant Protection of Yangzhou University as the material. This variety is widely cultivated and used in production. The number is 3 to 5:

[0021] (1)H 2 o 2 The preparation of solution: the 30%H that the present invention uses 2 o 2 Reagents were purchased from Shanghai Lingfeng Chemical Reagent Co., Ltd., and H 2 o 2 Prepare 50mmol L with distilled water -1 , all solutions are ready-to-use.

[0022] (2) Treatment time: From the time when the peony plants were exposed to the ground and spread their leaves (March 29, 2018), 80 plants each with basically the same growth status were selected, and the plants were subjected to H treatment using a sprayer. 2 o 2 Foliar spraying of solution and deionized water (control) until the main flower buds dew (April 26, 2018). Each spraying should be carried out in the evening in fine...

Embodiment 2

[0026] Basically the same as Example 1, the only difference is that H 2 o 2 The concentration of the solution is 10mmol L -1 , sprayed 6 times, monitored according to the method of Example 1, the result can be H 2 o 2 After treatment, the number of side branches decreased by 73.20%, and the length and thickness of side branches also decreased by 50.88% and 23.43%, respectively. In addition, H 2 o 2 The stem diameter and mechanical strength of the main stem under the treatment were also significantly increased compared with the control.

Embodiment 3

[0028] Basically the same as Example 1, the only difference is that H 2 o 2 The concentration of the solution is 100mmol L -1 , sprayed 4 times, monitored according to the method of Example 1, the result can be H 2 o 2 After treatment, the number of side branches decreased by 85.80%, and the length and thickness of side branches also decreased by 69.67% and 40.55%, respectively. In addition, H 2 o 2 The stem diameter and mechanical strength of the main stem under the treatment also showed a very significant increase compared with the control.

Abstract

The invention discloses the application of hydrogen peroxide in regulating the growth and development of side branches of peony cut flowers, that is, spraying the hydrogen peroxide solution on the branches and leaves of the peony during the growth process from the leaf spreading stage to the blooming stage. Compared with the prior art, the method of the present invention has the following advantages: (1) the method is easy to operate, safe and pollution-free, can greatly save labor costs, and can be applied on a large scale in field production of peony cut flowers; (2) the method The effect of the method is remarkable, not only can effectively regulate the growth and development of side branches of cut peony flowers, reduce the number of side branches by more than 70%, but also increase the thickness of the main stem by more than 10%, and increase the mechanical strength of flower stems by more than 12%, significantly improving the quality of cut flowers of peony .

Description

technical field [0001] The invention relates to the application of hydrogen peroxide in regulating the growth and development of side branches of peony cut flowers, and belongs to the technical field of peony cultivation. Background technique [0002] Peony (Paeonia lactiflora Pall.) is a traditional famous flower originating in China. Now it has become a popular high-end cut flower in the international market and is widely used in weddings, celebrations and other festive occasions. As an ideal peony cut flower, it should not only have excellent flower shape, flower color, flower fragrance, flower stem, vase performance, etc., but also have the same characteristics as chrysanthemum, rose and other plants with few or no side branches. Traditional Chinese peony varieties are mainly used for garden cultivation and potted plants. When breeding varieties, they did not focus on side branches, but paid more attention to flower shape, flower color, flower fragrance, flower stems and...
