Technical Field
[0001] This utility model relates to the field of Dendrobium cutting technology, specifically to a Dendrobium cutting planting column. Background Technology
[0002] Dendrobium orchids are a type of orchid, mainly distributed in tropical and subtropical Asia, Australia, and Pacific islands. In my country, they are mostly found in the southwest, south, and Taiwan. The main varieties of Dendrobium orchids include Dendrobium nobile, Dendrobium densiflorum, and Dendrobium chrysanthum. They can be used in medicine and are called Dendrobium. They have effects such as relieving deficiency heat and nourishing essence and yin. With the rise of the flower industry, Dendrobium orchids have also become an ornamental plant. When propagating Dendrobium orchids by cuttings, in order to improve the survival rate, planting columns are usually used to simulate the growth habit of Dendrobium orchids growing epiphytically on tree trunks or rocks in the natural environment. The column provides support, moisture and nutrient supply. However, the current planting columns used for Dendrobium orchid cultivation have poor air permeability, which affects the growth of Dendrobium orchids. Utility Model Content

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0016] like Figures 1-4 As shown, this utility model provides a Dendrobium cutting propagation column, including a column cylinder 1, which is a hollow cylindrical structure with an open top. Planting grooves 2 are evenly arranged on the outer wall of the column cylinder 1. A communication port 3 is opened in the wall of the column cylinder 1 located in the planting groove 2, connecting the inside of the column cylinder 1 and the planting groove 2. An isolation cylinder 4 is arranged in the column cylinder 1 along the same axis as the column cylinder 1. A plurality of ventilation holes 41 are evenly opened on the side wall of the isolation cylinder 4. A substrate for planting Dendrobium is arranged in the interlayer between the column cylinder 1 and the isolation cylinder 4 and in the planting groove 2. Dendrobium is inserted into the substrate in the planting groove 2. Planting substrates, such as soil, bark, moss, and sawdust, are added to the interlayer between the column 1 and the isolation cylinder 4, as well as to the planting trough 2. The planting trough 2 and the substrate in the interlayer are connected by a connecting port 3. Dendrobium seedlings are inserted into the planting trough 2. The substrate in the interlayer can provide more nutrients to the Dendrobium surface. The ventilation holes 41 set on the isolation cylinder 4 make the substrate for Dendrobium cuttings more breathable, providing more oxygen to the roots of Dendrobium and promoting Dendrobium growth. In addition, the substrate in the planting trough 2 is connected to the substrate in the interlayer between the column 1 and the isolation cylinder 4, which can provide more nutrients to Dendrobium and make Dendrobium grow well.
[0017] The bottom of the column 1 is connected to a hollow support base 5, and the bottom of the column 1 is evenly provided with filter holes 51 that communicate with the inside of the support base 5. The support base 5 can stabilize the planting column and prevent it from tipping over. Water can be poured into the substrate through the interlayer between the column 1 and the isolation cylinder 4 to provide moisture for the Dendrobium. Excess water can be filtered through the filter holes 51 and stored on the support base 5. At the same time, it can maintain the moisture content at the bottom of the substrate and avoid water waste.
[0018] The support base 5 has overflow holes 6 on its side wall. The overflow holes 6 allow excess water to flow out, preventing excessive water from accumulating in the substrate, reducing the substrate's permeability, and affecting the growth of Dendrobium.
[0019] The top edge of the support base 5 is provided with a baffle 7, and a receiving groove is formed inside the baffle 7. The receiving groove can catch substrate or Dendrobium leaves that accidentally fall from the planting trough 2, preventing the substrate and leaves from falling to the ground and causing pollution. By catching them in the receiving groove, the fallen leaves and substrate can be centrally processed.
[0020] A pressure pump 8 is installed on the side wall of the support base 5. The water inlet of the pressure pump 8 is connected to the inside of the support base 5, and the water outlet of the pressure pump 8 is connected to a water supply pipe 9. The upper end of the water supply pipe 9 is located above the interlayer between the column cylinder 1 and the isolation cylinder 4. The water stored in the support base 5 is pumped to the top by the pressure pump 8 to water the substrate a second time, thereby reusing water resources and saving water resources.
[0021] Multiple water distribution pipes 10 are evenly connected to the upper side wall of the water supply pipe 9, and the ends of the water distribution pipes 10 are located above the interlayer between the column cylinder 1 and the isolation cylinder 4. The water distribution pipes 10 can divide the water drawn from the support base 5 into multiple streams to evenly irrigate the substrate and avoid uneven watering.
[0022] Work process: Planting substrates, such as soil, bark, moss, and sawdust, are added to the interlayer between the column 1 and the isolation cylinder 4, as well as to the planting trough 2. The planting trough 2 and the substrate in the interlayer are connected by a connecting port 3. Dendrobium seedlings are inserted into the planting trough 2. The substrate in the interlayer can provide more nutrients to the Dendrobium surface. The ventilation holes 41 on the isolation cylinder 4 ensure good aeration of the substrate for Dendrobium cuttings, providing more oxygen to the roots and promoting Dendrobium growth. Water can be poured into the substrate through the interlayer between the column 1 and the isolation cylinder 4 to provide moisture to the Dendrobium. Excess water can be filtered through the filter holes 51 and stored on the support base 5. The water stored in the support base 5 is pumped to the top by the pressure pump 8 for secondary watering of the substrate, thus reusing water resources and saving water resources.
[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
