Application of aluminum citrate to hydrangea macrophylla color adjustment and control

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-...

AI Technical Summary

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 widely used in the petrochemical industry at present, and it is a cross-linking agent commonly used in weak gels under low temperature, acidic or neutral oil reservoir conditions (Lin Meiqin, Song Jinhong, Tang Yalin, Dong Zhaoxia, Li Mingyuan, Wu Zhaoliang.

Synthesis of Aluminum Citrate and Weak Coagulation of HPAM / Aluminum Citrate Preparation of glue system. Drilling and Mining Technology, 2010,33(5):89-92.), while aluminum citrate is used in the field of plant cultivation, especially in the aspect of flower color control in flower production, there are no related research reports
