Method and device for controllable cracking of stem of dioscorea elephantipes

Abstract

An embodiment of the invention provides a method and device for controllable cracking of a stem of dioscorea elephantipes. The method comprises the steps of selecting a dioscorea elephantipes plant about to enter a cracking period; installing a hollowed-out mold on the outer side of the stem of the dioscorea elephantipes plant; stimulating the surface of the stem of the dioscorea elephantipes plant below a hollowed-out area of the hollowed-out mold, and accelerating lignification generation; and removing the hollowed-out mold, carrying out conventional planting, and enabling the stem of the dioscorea elephantipes plant to crack along a shielding area of the hollowed-out mold. According to the method and device in the embodiment of the invention, the surface of the stem is locally shielded,and lignification generation of part of the hollowed-out area is accelerated; in the subsequent growth process of the dioscorea elephantipes, the surface of the stem of the shielding area is soft andactive epidermis, under the action of continuous growth and expansion and enlargement inside the stem of the dioscorea elephantipes, the active epidermis cracks firstly, and therefore, manual intervention and control over the cracking process and the cracking state of the stem of the dioscorea elephantipes are achieved, the form of the cracked plant meets the expected ornamental effect of people,and the output ratio of good-product plants is increased.

Description

technical field

[0001] The invention belongs to the technical field of agricultural planting, and relates to a method and a device for the controllable cracking of a tortoiseshell dragon stem. Background technique

[0002] Dioscorea macrostachya is a stem-shaped succulent plant belonging to the family Dioscorea and the genus Dioscorea macrostachya. The surface of the semi-spherical stem of the perennial tortoise dragon has wood cork on the surface, and there are gentle tortoise shell-like cracks on the wood cork. There are concentric polygonal wrinkles on each tortoise shell, which resembles "tortoise shell", while the slender trailing stem resembles "dragon shell". ", and the name "Turtoise Dragon" is also derived from this. For a tortoiseshell plant with high ornamental value, on the one hand, the size and shape of each tortoise shell should be as consistent as possible, preferably regular pentagonal or regular hexagonal; Cracks should be as uniform in width and depth as...
