Fresh keeping agent for prolonging carnation cut flower vase life and preparation method thereof

Abstract

The invention discloses a fresh-keeping agent for improving the vase life of carnation cut vases, which is composed of the following components according to the mass percentage: 12%-18% of cactus two extracts, 1%-5% of Chinese prickly ash, and 0.5%-0.8 of Panax notoginseng %, Capsicum 2%-6%, Gastrodia elata 7%-15%, Chitin 3%-7%, Pepper 0.5%-1.5%, Clove 0.5%-1.5%, Galangal 0.5%-1.5%, Diatomaceous earth 2%‑6%, the balance is water. The present invention also provides a method for preparing a preservative for improving the life of cut carnation vases. The present invention aims at prolonging the life of cut vases and achieving ecological preservation, and screens out a relatively cheap, green and environmentally friendly new environmental protection agent. Preservative for cut flowers.

Description

technical field

[0001] The invention belongs to the field of garden engineering, and in particular relates to a preservative for improving the lifespan of cut carnation vases and a preparation method thereof. Background technique

[0002] Fresh-cut flowers are a farm product with ornamental value. Its commodity value is closely related to the ornamental quality of fresh-cut flowers. The ornamental quality can be reflected by the size, color, leaf color, and viewing time of buds and petals. After fresh cut flowers are harvested, they are very perishable, and the loss rate of cut flowers is about 20%. The loss caused by improper preservation is as high as 40%-50%. Therefore, it is very important to use comprehensive technology to prolong the life of fresh cut flowers, prolong their turnover period and commodity ornamental value. There are many factors restricting the production of fresh cut flowers, among which the preservation of cut flowers is the key issue.

[0056] A preparation method of a preservative for improving the longevity of cut carnation vases, comprising the following steps: drying the cactus in the shade, adjusting the drying oven to 35-40°C, drying for 12 hours, pulverizing the material with a powder machine, and passing through 20 meshes Sieve, pack into bags separately, store at 4°C for later use; weigh 50g of the crushed cactus plant sample, add quantitative 95% ethanol, the standard is to soak the sample by more than 4cm according to the sample volume, soak, put it in a shaker and shake for 48h. Suction filtration under reduced pressure to obtain the filtrate and residue; add an appropriate amount of 95% ethanol to the residue extracted for the first time, just immerse the sample for 1 cm, soak it, and shake it in a shaker for 24 hours. Suction filtration under reduced pressure to obtain the filtrate and residue; add an appropriate amount of 95% ethanol to the above residue, just submerge the sample, soak, and shak...
