Embodiment 1

[0017] The cut rose 'Samansha' was purchased from a farmer in Dounan, Kunming. The harvesting standard is a flowering index of 3, and a total of 1900 branches were taken. According to the flower stem length of 40cm above, leave 2 to 3 pairs of leaves and remove the thorns. 20 branches make a bundle. 15 bundles (300 branches) of flowers are used for each treatment, and there are 3 combinations in total.

[0018] Treatment combination 1-- 0 + water absorption

[0019] Treatment combination 2--cold storage pre-cooling + suction pretreatment

[0020] Treatment combination 3--vacuum precooling + suction pretreatment

[0021] Vacuum pre-cooling treatment method: trim the bases of the cut flower stems and put them into a container with a concentration of 0.8 times the preconditioning solution. Insert the temperature-sensing probe into the pretreatment solution, put the container with cut flowers into the vacuum tank, start the vacuum pump, reduce the pressure of the vacuum tank t...

Embodiment 2

[0033] The cut carnations 'Isac' and 'Dona' were purchased from farmers in Dounan Village, Guandu District, Kunming City. The harvesting standard is flowering index level 2, with a total harvest of 3600 branches. Arrange the obtained flowers, the length is 40cm, and each tie is 20 branches. The processing procedure is the same as that of rose cut flowers. The 6 processing combinations are:

[0034] Treatment combination 1--vacuum precooling + no water supply;

[0035] Treatment combination 2--vacuum precooling + water spray;

[0036] Treatment combination 3--vacuum pre-cooling + water absorption;

[0037] Treatment combination 4--vacuum precooling + suction pretreatment

[0038] Treatment combination 5-- 0 + water absorption

[0039] Treatment Combination 6--Cold Storage Precooling + Suction Pretreatment

[0040] The method of replenishing water in vacuum precooling includes two treatments: water spraying and water absorption, and the measure of not giving any water rep...

Embodiment 3

[0048] Cut flower Limonium 'Deep Blue' was purchased from Kunming Xianke Sijiqing Flower Company. The harvesting standard is that more than 80% of the sepals are opened, and a total of 5500g of flowers.

[0049] Processing method Arrange the flower materials, the flower stem is 60cm long, 500g is a bunch, and it is divided into 7 treatments. The processing combination is:

[0050] Treatment combination 1--vacuum precooling + no water supply

[0051] Treatment combination 2--vacuum precooling + water spray

[0052] Treatment combination 3--vacuum pre-cooling + water absorption

[0053] Treatment combination 4--vacuum pre-cooling + pre-cooling process suction pre-treatment liquid

[0054] Treatment combination 5--vacuum precooling + degassing process suction pretreatment liquid

[0055] Handling combination 6-- 0 + 0

[0056] Treatment Combination 7--Cold Storage Pre-cooling + Suction Pretreatment

[0057] After treatment, it was transported at 17°C for 72 hours, and the ...

Abstract

This invention provides a way to preserve water from the flowers un the process of vacuum pro-coldness when cut flowers. The factory is put the tidied flowers stem into the container with enough liquor. Ensure that the stem is under liquor. Put the probe into the liquor in the same time, and then put the container with flowers into the vacuum jug. Start the vacuum pump to depress the air pressure, accommodate the temperature to the required standard, close the vacuum pump, and then recover to normal pressure. This way can decrease the depletion of flowers in transport decreased water depletion, solved the problem of long distance transport. Promote the development of flowers commerce in our nation and other nations.

Description

technical field [0001] The invention relates to the technical field of post-harvest cut flowers, in particular to the field of transportation and preservation of cut flowers. Background technique [0002] The flower industry is one of the most dynamic industries in agriculture in the world today. At present, the global flower consumption is 50 billion US dollars, of which 40 billion US dollars are cut flowers. China has become the country with the largest flower planting area in the world. In 2003, the flower planting area reached 430,000 hm 2 , of which the planting area of ​​cut flowers reached 24,000 hm 2 , with an annual output of 6.7 billion cut flowers. [0003] The production area of ​​my country's cut flowers accounts for 30% of the world's total area, but the trade volume only accounts for 1.3% of the world's total trade volume. One of the important reasons is that the loss of my country's cut flowers in long-distance transportation is as high as 40%. The post-h...
