Problems solved by technology

Therefore, at the present stage, hydrangea production enterprises adopt the method of applying aluminum fertilizer in the soil to control hydrangea plants to produce blue hydrangea, which is time-consuming and laborious, and due to the complex soil environment and the influence of other fertilizers and irrigation water, it is difficult to achieve the desired effect. Accuracy of flower color control and consistency of color chroma in blue hydrangea
In addition, after hydrangea cut flowers are separated from the body, because the hydrangea flower ball is large and the petals are soft, it is easy to dehydrate and cause the flower branches to wilt, so it is difficult to use chemical dyes to turn the cut flowers blue.
[0005] Aluminum citrate is wide

Embodiment 1

[0023] Example 1 Study on aluminum citrate regulation and control of blue color of hydrangea cut flowers

[0024] Taking distilled water as a control, add 0.55g / L, 1.1g / L, 2.2g / L aluminum citrate and 3.3g / L aluminum sulfate octadecahydrate to 1 liter of distilled water respectively, and mix them to prepare four kinds of aluminum ion-containing Aqueous solution, the final concentrations of aluminum citrate in the three aluminum citrate aqueous solutions are 0.0025mol / L, 0.005mol / L and 0.01mol / L respectively, and the final concentration of aluminum sulfate in the aluminum sulfate aqueous solution is 0.005mol / L.

[0025] These four kinds of aluminum ion aqueous solutions were used to carry out comparative experiments on the control of flower color of hydrangea cut flowers. The cut flowers of three hydrangea varieties "Shioni", "Tiana" and "Joker" were used to test, and the vase life of hydrangea cut flowers and the color change time of cut flowers were measured. The results are s...

Embodiment 2

[0034] Example 2 Effects of color-regulating fresh-keeping solutions with different concentrations of aluminum citrate on vase life, blue-turning time and shape of hydrangea cut flowers

[0035] Mix 10g of sucrose with 900ml of distilled water until the sucrose is completely dissolved to obtain a sugar source solution, then add 8-HQ, citric acid, rosmarinic acid, salicylic acid lemon and aluminum citrate into the sugar source solution respectively to make The content of 8-HQ is 200mg / L, the content of citric acid is 200mg / L, the content of rosmarinic acid is 50mg / L, the content of salicylic acid is 50mg / L, stir until the solid dissolves, and finally add distilled water to dissolve The solution is fixed to 1 liter, and 1 liter of cut hydrangea fresh-keeping solution is obtained. Add 0.55g / L, 1.1g / L and 2.2g / L aluminum citrate respectively in the described 1 liter of hydrangea cut flowers fresh-keeping liquid, mix and prepare three kinds of hydrangea flower color regulation fres...

Embodiment 3

[0049] Embodiment 3 Detection of aluminum ion content in cut hydrangea petals and flower branches

[0050] (1) Determination of the content of aluminum ions in the petals and branches of cut flowers of ‘Shioni’ in the flower color control preservation solution

[0051] Insert the cut flowers of hydrangea variety 'Shioni' into the preservative solution of Formula 2 (see Table 4 of Example 2), and take petals and flower branches at different vase insertion times to detect the aluminum ion content therein. For the detection method of aluminum ion content used in this example, please refer to Zhang Meiyan (Zhang Meiyan, Liu Yanpei, Zhang Yingjun, Yuan Fujin, Zhong Sheng, Xue Shiming. Effects of exogenous silicon on the morphological construction of Dactylis chinensis and the accumulation of aluminum in plants under aluminum stress[J] .Southwest Agricultural Journal, 2017,30(5):1137-1144) method (the following detection is the same).

Abstract

The invention discloses an application of aluminum citrate to hydrangea macrophylla color adjustment and control, and belongs to the technical field of flower and plant preservation and flower color regulators. According to the application, hydrangea macrophylla cut flowers are placed into 0.55-1.1g/L aluminum citrate flower color regulators, red or pink hydrangea macrophylla cut flowers can turnpurple and then turn blue within 2-4 days at a vase phase, so that hydrangea macrophylla color (blue) is adjusted and controlled in the field in the hydrangea macrophylla planting process, labor and production costs are greatly saved, controllability of the quality of cut flower products is improved by enterprises, and ornamental values, interestingness and additional values of fresh hydrangea macrophylla cut flowers are enhanced.

Description

technical field [0001] The invention belongs to the fields of flower preservation and color adjustment, and in particular relates to the application of aluminum citrate in the control of hydrangea flower color, especially in the control of blue hydrangea cut flowers. Background technique [0002] Hydrangea macrophylla, also known as hydrangea or hydrangea, is native to China and is a deciduous shrub. Its flowers are large and showy, and the colors are rich and varied, including red, white, blue, pink and some transitional colors. It is an important The garden ornamental plants have high ornamental, ecological and economic value. Hydrangeas were cultivated as landscaping and potted flowers in the early days. In recent years, they have been used for fresh-cut flower production. They have become the sixth largest fresh-cut flowers after the five major fresh-cut flowers (Li Qing. Research progress and development prospects in Tibet [J]. Tibet Science and Technology, 2019, 2:66-...
