Embodiment 1

[0024] see figure 1 , the orchid plant seedling raising device of the present embodiment is made of water inlet valve 1, water tank 2, support pipe 3, siphon 4, filter screen 5, support 6, water outlet valve 7 and seedling raising tray 8.

[0025] The bottom of the water tank 2 of the present embodiment is fixed on the support 6 with threaded fasteners, and the bottom of the water tank 2 is processed with a drain port, and the left side wall of the water tank 2 is processed with a 6 cm bottom from the water tank 2. The water inlet is provided with a water inlet valve 1 on the water inlet, and communicates with the water inlet pipeline through the water inlet valve 1. Water tank 2 depth is 6cm, and 3 drainage holes are installed on its right side edge, and drainage hole installation position is apart from top 2.75cm, 3.35cm and 6cm. The bottom of holding water tank 2 is equipped with 4 support pipes 3, is distributed in a rectangular array, places seedling raising dish 8 on th...

Embodiment 2

[0037] The seedling raising tray 8 of the present embodiment is a rectangular tray made of PE material, with 2 × 3 water permeable holes evenly distributed on the bottom of the plate, and water seepage holes are processed at the vacant positions on the periphery of the water hole, and the porosity of the water seepage holes reaches 5. %, to ensure that the moisture in the seedling tray 8 penetrates and the cultivation substrate is ventilated. In this embodiment, the permeable holes are two kinds of large and small holes distributed at intervals. The diameter of the large hole is 0.3mm, and the diameter of the small hole is 0.2mm. The distance between the hole and the adjacent permeable hole is 3cm.

[0038] The siphon tube 4 of this embodiment is designed as an inverted funnel shape, the diameter ratio of the upper and lower ports is 1:1.6, and the taper is 0.75, that is, the upper port of the siphon tube 4 with a large hole is 0.3 mm, the lower port is 0.48 mm, and the small ...

Embodiment 3

[0049] The seedling raising tray 8 of the present embodiment is a rectangular tray made of PE material, with 5 × 3 water permeable holes evenly distributed on the bottom of the plate, and water seepage holes are processed in the vacant positions on the periphery of the water permeable holes, and the porosity of the water seepage holes reaches 10. %, to ensure that the moisture in the seedling tray 8 penetrates and the cultivation substrate is ventilated. In this embodiment, the permeable holes are two kinds of large and small holes distributed at intervals. The diameter of the large hole is 0.2mm, and the diameter of the small hole is 0.1mm. The distance between the hole and the adjacent permeable hole is 2.5cm.

[0050] The siphon tube 4 of this embodiment is designed as an inverted funnel shape, the diameter ratio of the upper and lower ports is 1:1.75, and the taper is 0.75, that is, the upper port of the siphon tube 4 with a large hole is 0.2 mm, the lower port is 0.35 mm,...

Abstract

The invention relates to an orchid seedling growing device. The orchid seedling growing device comprises a support and a water containing groove formed in the support, wherein a supporting pipe is arranged on the bottom of the water containing groove, seedling growing trays are arranged on the top of the supporting pipe, permeable holes and water leakage holes are machined in the bottoms of the seedling growing trays, a filter screen is arranged on each permeable hole, the bottom of each filter screen is connected with a siphon, the lower end of each siphon extends into the water containing groove, each siphon is in the shape of a reversely arranged funnel, and the lengths of the siphons range from the second-grade to the fifth-grade according to the distribution heights and meet the formula L=lambda rga / V. According to the orchid seedling growing device, water in the water containing groove is led into the seedling growing trays according to the siphon principle, nutrients and water can soak into the seedling growing trays from the bottoms of the seedling growing trays, different water requirements of orchids in different growth stages are met, the amount of water in each seedling growing tray is controlled reasonably, water and nutrients are utilized efficiently, the survival rate of the orchids is increased, the problems that in the prior art, the growing difficulty of the orchids is high and the survival rate of the orchids is low are effectively solved, and the orchid seedling growing device is suitable for large-scale orchid seedling growing bases.

Description

technical field [0001] The invention relates to a seedling raising device suitable for orchid plants. Background technique [0002] Orchidaceae is a large family widely distributed around the world, including many famous precious flowers and medicinal plants (such as Cymbidium, Tianma, Baiji, Dendrobium officinale, etc.), in view of its unique ornamental value and high medicinal value Value has long been highly concerned by people. [0003] Under natural conditions, Orchidaceae seeds are extremely small and only have undifferentiated embryos, which cannot provide the nutrients needed for plant germination, so artificial cultivation is more difficult. In recent years, the wild resources of Orchidaceae have decreased sharply, and tissue culture technology is mainly used in production to complete a large number of rapid propagation of test-tube seedlings. However, tissue culture has the characteristics of high environmental requirements, long initial germination time, and hig...
