Description

A kind of fresh-cut vase of Xia chrysanthemum vase preservation liquid and method for improving the life of cut vase vase

technical field

The invention relates to a fresh-keeping liquid for flowers, in particular to a fresh-keeping liquid for vase insertion of Xia chrysanthemum and a method for improving the service life of the vase of cut flowers.

Background technique

Chrysanthemum is native to China. It is one of the top ten famous flowers in my country and one of the four largest cut flowers in the world. It is the second largest trade flower in the world after Chinese rose, and occupies a very important position in flower production. In 2019, the export value of chrysanthemum in my country accounted for 34.67% of the total export value of fresh cut flowers in that year, and it is the fresh cut flower with the largest export share and the most competitive market advantage. At present, the domestic market has a large demand for fresh cut chrysanthemum flowers, but the aging of fresh cut chrysanthemum flowers restricts its storage, transportation and ornamental quality, and affects the economic value and industrial development of fresh cut chrysanthemum flowers. In particular, the leaves of Xia chrysanthemum are prone to wilting and yellowing after being subjected to high temperature or rain stress, which seriously affects the economic value of cut flowers.

The composition of the existing preservatives is complex, and 8-hydroxyquinoline or related salt compounds are often used as fungicides, which are not very friendly to the environment and have certain toxicity. in the list of items. These preservatives have a certain fresh-keeping effect on Xia chrysanthemum, but the effect is not outstanding, and the problem of easy wilting of leaves has not been well resolved, resulting in the failure to further improve the quality of Xia chrysanthemum cut flowers after harvesting, affecting the development of Xia chrysanthemum cut flower industry. There is a need on the market for a preservative with simple preparation, low cost, environmental friendliness and remarkable effect.

Detailed ways

The technical solutions of the present invention will be further described below with reference to the accompanying drawings.

Example 1

A fresh-cut vase-insertion preservation solution for Xia chrysanthemum, comprising: 0.02% sodium hypochlorite, prepared from water.

The harvested cut flowers were rehydrated overnight, and the flower branches were cut diagonally in the water, so that the distance from the base of the cut flowers to the top of the flower stem was about 55cm, and the same number of leaves in good condition were retained. The fresh-keeping period of the vase can reach 12 days; as shown in Figure 2, within 12 days, only part of the leaves are withered and yellow, and the rest of the leaves are green and in good condition.

As shown in Figure 1, the average longest vase life of leaves can reach 12 days, the longest vase life of flowers is more than 20 days, and the maximum flower diameter is about 80 mm. These three ornamental indicators are significantly better than those without preservative liquid treatment. Fresh cut flowers from the same batch.

However, the same batch of fresh cut flowers that were not treated with the bottle-inserted fresh-keeping solution in the present example were inserted into clear water, and the phenomenon of wilting and drooping of the leaves appeared in only 3 days, so that the leaves of the cut flowers lost their ornamental value; The diameter is only about 55 mm. On the 11th day after the bottle was inserted, the flowers wilted and senesced, and the leaves and flowers lost their ornamental value.

Example 2

A fresh-cut vase-insertion preservation solution for Xia chrysanthemum, comprising: 0.01% sodium hypochlorite, prepared from water.
