The utility model provides a rice planting
buoyancy tank, which relates to the technical field of rice planting, and comprises a
buoyancy tank body, a planting groove frame arranged in the
buoyancy tank body, and a fixing
assembly arranged in the buoyancy tank body, the fixing
assembly comprises a grid frame, a placing groove, a water absorption
sponge and a
sponge strip; the connecting assemblies are arranged on the two sides of the buoyancy tank body, and each connecting
assembly comprises a connecting sleeve, a movable rod, a limiting plate and a fixed sleeve. According to the floating box for rice planting, the fixing assemblies can effectively stabilize the rice substrate layer in the containing groove, the substrate layer is prevented from floating,
plant positions are prevented from being unstable,
rice plants can absorb
nutrient substances of the substrate layer better and conveniently, through arrangement of the connecting assemblies,
connectivity between the box bodies of the floating box is enhanced, the situation that the floating box falls apart in
severe weather is avoided, and the service life of the floating box is prolonged. And the movable rods move in the fixed sleeves, so that it is ensured that the buoyancy tank bodies are disassembled easily, and the buoyancy tank bodies can be collected more conveniently and rapidly.
