Problems solved by technology

[0003] Although some existing preservatives commonly used for fresh-cut flowers such as silver thiosulfate, silver nitrate, organic acids, and plant growth regulators have certain applications in the field of fresh-keeping, and can prolong the flowering period of cut flowers and improve the fresh-keeping effect, there are also many deficiencies. The main manifestations are: 1. Preservatives containing silver ions have high physiological toxicity and are easy to pollute the environment; 2. Some agents are unstable in nature and prone to discoloration and blackening in the later stage; 3. Some will cause The color of cut flowers is distorted, and there is bad smell 4. Some have no insecticidal and antibacterial functions, and some are easy to cause blockage of flower stems, which is unfavorable for cut flowers to absorb water and cause wilting
5. Some commonly used preservatives for cut flowers may be better for other cut flowers, but the effect for cut flowers of eustoma is not outstanding
