Detailed Implementation
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Please see Figure 1 - Figure 4As shown in the figure, the substrate container for hydroponically grown strawberries in a greenhouse proposed in this embodiment includes a cultivation rack 1. The cultivation rack 1 includes two horizontally opposite support rods 11. The support rods 11 are preferably made of corrosion-resistant, high-strength aluminum alloy square tubes or UPVC pipes. Their length can be customized according to the actual width of the greenhouse. Each support rod 11 has a water inlet 111 and a mounting hole 112 at both ends. The water inlet 111 is a standard internal threaded interface or quick-connect plug for connecting to an external water supply system. The mounting hole 112 is used to fix the entire cultivation rack 1 to the truss on the top of the greenhouse or the side column by expansion bolts or hanging parts to ensure its stability.
[0034] Two main PVC pipes 12 are installed parallel to each other between the two support rods 11. The main PVC pipes 12 are UPVC or PE water supply pipes with a diameter of 20-25mm. Their two ends are sealed to the water supply interfaces 111 on the support rods 11 through unions or flanges, forming a closed annular main water supply passage. This design helps to reduce water pressure loss and ensure uniform water flow distribution. Furthermore, on the opposite side of the two main PVC pipes 12, multiple connection ports 121 are machined at equal intervals (30-50cm apart) along the length direction. The connection ports 121 can be external threaded interfaces or socket joints.
[0035] Multiple branch pipes 13 (PE pipes for micro-irrigation with a diameter of 10-15mm) are horizontally arranged between two main pipes 12, and their ends are connected to two corresponding connectors 121 on the two main pipes 12, thus forming a multi-layered, parallel branch pipe network between the two main pipes 12 (the spacing of the branch pipes 13 determines the longitudinal density of the cultivation).
[0036] Each branch pipe 13 has multiple branch connectors 131 installed at equal intervals (e.g., 20-25cm intervals) along its length. The branch connectors 131 are water outlet connectors for micro-irrigation. Their lower ends are tightly connected to the branch pipe 13 by threads, and their upper ends are designed with external threads.
[0037] The bottom of the culture container 2 is machined with internal threads, which can be directly screwed onto the external threads on the upper end of the diverter 131 for quick installation and sealing. Each culture container 2 includes an outer sleeve 21, a sterile sponge body 22, and an inner sleeve 23.
[0038] The outer sleeve 21 is injection molded from opaque, aging-resistant PP or ABS plastic, serving to block light (prevent algae growth) and provide structural support. A ring-shaped limiting groove 211 is machined on its upper inner side.
[0039] The inner sleeve 23, also made of food-grade plastic, is nested inside the outer sleeve 21. A limiting ring 231, which fits into the limiting groove 211, is provided on its upper outer side. By rotating the limiting ring 231 into the limiting groove 211, the inner sleeve 23 is fixed in the outer sleeve 21, but can be easily rotated out when needed. Multiple strip-shaped drainage grooves 232 are arranged in a circumferential array on the lower side wall of the inner sleeve 23 to ensure air circulation and drainage of excess liquid between the inner and outer sleeves.
[0040] The sterile sponge 22 fills the annular cavity between the outer sleeve 21 and the inner sleeve 23. This sponge is made of hydrophilic, fertilizer-retaining phenolic or polyurethane foam and has undergone high-temperature sterilization. Its function is to absorb and store the nutrient solution delivered from the diversion connector 131, and to continuously provide water and nutrients to the plant roots through capillary action, while simultaneously securing the plant's rootstock.
[0041] A small cultivation box 24 is fixed to the centerline inside the inner sleeve 23 via support legs. The cultivation box 24 has multiple drainage holes 241 on its side walls and bottom. When in use, strawberry seedlings are planted in the cultivation box 24, and their roots can grow outward through the drainage holes 241, extending into the surrounding moist sterile sponge 22 to absorb nutrients. The cultivation box 24 itself provides initial fixation and protection for the seedling substrate or seedling roots.
[0042] To further enhance the stability of the connection between the inner sleeve 23 and the outer sleeve 21 and prevent them from loosening and rotating due to accidental contact, a positioning mechanism 25 is provided.
[0043] The positioning mechanism 25 includes a positioning hole 251 that penetrates the side wall of the outer sleeve 21, a slidable positioning rod 252 installed in the hole, and a carbon steel ball 253 embedded at the end of the positioning rod 252.
[0044] A hemispherical positioning groove 233 is correspondingly provided on the limiting ring 231.
[0045] The end of the positioning rod 252 is connected to the moving rod 257, and the moving rod 257 is fixed on the moving plate 255.
[0046] The movable plate 255 is movably sleeved on the stabilizing rod 254 fixed to the outer sleeve 21. The stabilizing rod 254 is fitted with a tensioning spring 256, with the two ends of the spring pressing against the outer wall of the outer sleeve 21 and the movable plate 255, respectively.
[0047] The working principle of the substrate container for soilless strawberry cultivation in a greenhouse proposed in this embodiment is as follows: In use, the support rod 11 is fixed to a support at an appropriate height in the greenhouse through the mounting hole 112 and screws. The main pipe of the external nutrient solution supply system is connected to the water inlet 111 at the end of the support rod 11. The nutrient solution flows sequentially through the support rod 11, the main pipe 12, and the branch pipe 13, and finally seeps out from each branch connector 131 and enters the corresponding cultivation container 2. The nutrient solution first wets the sponge 22 at the bottom of the outer sleeve 21, and then diffuses upward under capillary action, keeping the entire sponge 22 moist. The strawberry seedlings are planted in the cultivation box 24 of the inner sleeve 23. Their roots penetrate the drainage hole 241 and enter the moist sponge 22 to absorb nutrients and water, and grow healthily.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
