Technical Field

[0001] The utility model belongs to the technical field of flower ethylene detection, and in particular relates to an auxiliary device for flower ethylene concentration detection. Background Art

[0002] The wilting signal of ornamental flowers is closely related to the increase of endogenous ethylene. The release rate of ethylene has always been an important indicator in the field of flower preservation, especially in cut flowers. At present, the determination of ethylene release rate mainly measures the concentration of ethylene per unit time and per unit volume. However, traditional tools for measuring the ethylene concentration of cut flowers are generally based on gas collection bottles and sealed plastic boxes. These devices often have problems such as difficulty in replacing the preservative solution, difficulty in accurately calculating the volume of the container, and difficulty in accommodating the cut flower stems due to their long stems, and the inability to completely fix the cut flowers.
