Description

Gardening pillar

Technical field

The present invention relates to accessories for gardening, and in particular to a horticultural pillar.

Background technique

In the field of agricultural production, farmers usually use wooden poles or bamboo poles to form shelves to help grow vines and climbing plants. Commonly, there are loofah, lentils and tomatoes. Although these woods or bamboo poles are environmentally friendly, they are exposed to the sun. There will be aging fractures, which on the one hand is not conducive to plant growth, on the other hand is a one-time use, wasting a lot of wood poles and bamboo poles. There is also a decorative flower field, and a flower stand is needed to assist the flower setting.

Therefore, there is a gardening rod specially designed for agricultural production and flower planting. The gardening rod includes a metal tube and a plastic layer coated on the metal tube. The plastic tube sleeve is respectively installed at both ends of the metal tube, and one plastic rod sleeve is It is easy to insert into the spike of the soil, and the other plastic rod cover is flat. For example, the Chinese Patent Publication No. CN203675780U, published on the Japanese Patent Publication No. 2014.07.02, discloses a high-strength horticultural pillar comprising a metal tube and a plastic layer coated on the surface of the metal tube. The two ends of the metal tube are in the shape of a truncated cone and a plastic layer. The surface has at least one auxiliary rib strip disposed along the axial direction of the metal tube, and the auxiliary rib strip is corrugated with respect to the surface of the plastic layer, and the two ends of the metal tube respectively have a pointed head sleeve and a flat head cover. The two sections of the metal tube of the high-strength horticultural pillar are in the shape of a truncated cone. Although the degree of damage of the plastic sleeve can be reduced to a certain extent when the strut is hammered, the plastic sleeve is still damaged after repeated use. In addition, the length of the horticultural pillar is fixed, and it is necessary to produce products of different lengths according to different needs of customers, resulting in an increase in costs in the procurement, production, waste disposal, transportation and other aspects of raw materials.
