Problems solved by technology

[0037] The production areas of cut chrysanthemums in my country are relatively concentrated, and the production of cut flowers is regionalized. The complementation between different places is mainly through long-distance transportation. After long-term transportation, the flowers will often be blocked or opened too quickly after the flowers are rehydrated, causing the flowers to wilt. , falling off, premature senescence and dryness of leaves, yellowing of stems and leaves, and reduced lifespan of vases, etc., resulting in losses of up to 30-40%.

Embodiment

[0109] Test methods and materials

[0110] The cut chrysanthemum 'Youxiang' was used as the test material, provided by Beijing Shuanghui Xinhua Horticultural Company. It was planted on April 14, 2012, and harvested on July 25. The company's conventional cultivation management was carried out. The length of the cut flower branch is 90cm, the diameter of the flower is about 20mm, the opening degree of the harvest is level 2, the leaves are dark green, the tongue-shaped flower is not damaged, and the flower branch is free of diseases and insect pests.

[0111] Simulated transportation test: After the cut chrysanthemums have undergone different fresh-keeping treatments, they are first placed in a 2°C freezer and treated with a pretreatment solution for 6 hours. After being taken out, they are packed and boxed, and placed in a 2°C freezer to simulate long-distance transportation. The refrigerated time is 18 days. After taking out, rehydration and vase test were carried out. The vas...

[0124] Example 1: Spray test of postharvest preservative

[0125] Cut chrysanthemum wilts due to dehydration of flower heads and leaves after harvesting and transportation. Therefore, fruit wax and another anti-transpiration agent are used to preserve freshness respectively, in order to form a film on the surface of leaves and flower heads to prevent water loss. In order to screen out the most suitable preservatives for cut chrysanthemums, the concentrations of the two preservatives were adjusted. The common name of selected fruit wax is morpholine fatty acid salt fruit wax (GB1248-2010, researched and developed by Gansu Academy of Agricultural Sciences). The selected anti-transpiration agent is a polymer compound (developed by the Beijing Garden Research Institute), which is a film-type anti-transpiration agent and is considered to reduce wilting of branches and leaves caused by excessive transpiration of leaves during tree transplantation. It has the effect of effectively m...

[0135] Example 2: Comparison of the effect of spraying fruit wax before harvest and spraying fruit wax after harvest

[0136] Due to the excellent effect of spraying fruit wax after harvesting, but there are situations where the flowers cannot be fully opened, considering improving the spraying time and seeking the best time for spraying preservatives, two spraying schemes are set up: (1) Spray 1:30 fruit wax dilution after harvest; (2) Spray 1:30 fruit wax dilution before harvest, and compare with no fresh-keeping solution. Carry out simulated transport tests.

[0137] It can be seen from Table 3 that the pre-harvest spraying of fruit wax (B2) was superior in the openness of flower heads, freshness of flower heads and leaves, and vase life after opening the box, which was different from that of post-harvest spraying of fruit wax (B1). Not significant, significantly better than the control. After opening the box, the opening degree of the flower head is relatively small, and...

Abstract

The invention provides a long-distance transportation comprehensive refreshing processing method of cut-flower chrysanthemum. The method comprises a step of sprinkling fruit wax on a cut-flower before transportation. The invention also provides a kit for carrying out refreshing processing on the cut-flower. The kit comprises (1) thidiazuron and (2) at least one of free 8-hydroxyquinoline, a citric acid, an ascorbic acid, sugar, triton and the fruit wax. The invention further provides an application of the kit in the refreshing processing of the cut-flower. The cut-flower chrysanthemum long-distance transportation comprehensive refreshing processing method provided by the invention has the advantages that the quality after transportation of the cut-flower is observably improved, and especially the flower opening quality and blade freshness quality are improved.

Description

technical field [0001] The invention relates to the field of fresh-keeping of cut flowers, in particular to the field of post-harvest fresh-keeping of cut chrysanthemums. Background technique [0002] The factors affecting postharvest senescence of fresh-cut flowers are very complicated, including endogenous material factors such as water, protein, sugar, amino acids, plant hormones, and exogenous environmental factors such as temperature, humidity, and light. [0003] Moisture is the most important factor affecting the quality of fresh cut flowers. The imbalance of water metabolism is the main reason for the decline of fresh cut flowers. The water content of most cut flowers usually reaches 70%-80%. Since the fresh cut flowers are harvested, the water supply from the parent root system is cut off, and the original water balance established between leaf transpiration and root water absorption is destroyed. cause dehydration stress. The vase life of fresh-cut flowers depen...
