    摘要: The rot-resistant plant support which is aesthetically pleasing and can be inexpensively produced consists of a rod section and a plastics material which can be colored. The interior of the rod is finely porous while the surface zone has bark-like protuberances. The plant supports are manufactured by extrusion at processing temperatures in the tool adjusted to between 5 and 30.degree. C. above the temperatures conventionally employed for extruding foams with a smooth surface from the same thermoplasts.
