Description

Technical Field

[0001] The utility model relates to the technical field of agricultural planting equipment, in particular to a rhubarb seed bud cutting device. Background Art

[0002] Rhubarb is a perennial medicinal material. There are two main ways to reproduce it. One is sexual reproduction, which is to use seeds for seedling cultivation and then reproduction. The other is asexual reproduction, which is to use the side buds produced during its growth process as seed buds for reproduction. Asexual reproduction saves time compared to sexual reproduction, and the rhubarb rhizome is full in the middle and not hollow. Therefore, most growers generally use seed bud reproduction.

[0003] There are two sources of seed sprouts. One is that after the rhubarb is dug, the workers cut the seed sprouts from the dug rhubarb. The other is that the workers cut the seed sprouts from the growing rhubarb. When cutting the rhubarb seed sprouts from the mother plant, it is generally required that the seed sprouts must be accompanied by a certain amount of rhizomes, especially the weaker seed sprouts must be accompanied, in order to ensure the survival rate of the rhubarb seed sprouts. In addition, when cutting the seed sprouts, the knife needs to be disinfected after each cutting to prevent cross infection between the seed sprouts. At present, the cutting of the seed sprouts mainly relies on kitchen knives, and the cutting efficiency is low, it is not labor-saving, the cutting quality is poor and inconsistent, and the knife and rhubarb seed sprouts are not disinfected.
