This utility model relates to the field of urban greening technology, and more particularly to a roadside green landscape belt for urban planning. The technical solution includes: a water storage tank is provided below the planting trough; a baffle is rotatably installed at the top of the planting trough via a hinge; the planting trough and the water storage tank are connected by a perforated plate, and fiber absorbent rods are inserted into the perforated plate. The fiber absorbent rods draw water from the water storage tank into the planting trough through capillary action, providing moisture for the plants in the planting trough; troughs are formed at both ends of the planting trough, and these troughs are connected to the water storage tank. A float is provided in the water storage tank, and a push rod is provided on the float. The push rod is movably connected to the baffle via a rotating seat. When the float moves up and down within the water storage tank, the float pushes the baffle to flip open via the push rod. This utility model achieves automatic opening and closing of the baffle according to the water level, precisely controlling the environment, creating suitable conditions for plant growth, and improving the efficiency of the green landscape belt.

This utility model belongs to the field of plant cultivation technology, specifically disclosing a transparent device for hydroponic plant cultivation using a solid substrate. It includes a cultivation container with a partition dividing it into an upper and lower cultivation section. The upper cultivation section contains nutrient soil, and the lower cultivation section contains nutrient water. The partition has multiple fine holes and perforations, with cotton fibers threaded through the perforations. The ends of the cotton fibers extend to the upper and lower cultivation sections respectively. The sidewall of the lower cultivation section has through holes. This utility model separates the nutrient soil and nutrient water layers using the partition and uses the through holes to drain excess water while simultaneously creating an air barrier. During plant growth, the roots extend from the fine holes in the partition into the nutrient water in the lower cultivation section, passing through the air barrier layer. This ensures the roots receive sufficient oxygen, preventing root rot. The through holes also facilitate observation of root growth, ensuring healthy plant growth.

The utility model discloses a kind of garden afforestation planting blanket, which is composed of at least two planting blanket units;Each planting blanket unit includes base layer, water storage layer, water-permeable layer and drainage layer arranged in order from top to bottom, and support layer arranged between the water storage layer and the water-permeable layer;The support layer forms multiple independent spaces inside for the growth of plant root systems, and the support layer is provided with a fixing structure on the peripheral edge portion for fixing after the edge portions of the support layers of the two adjacent planting blanket units are overlapped with each other;The utility model has a certain thickness due to the support layer, which forms a gap between the water storage layer and the water-permeable layer to facilitate air circulation, providing sufficient oxygen for plant root systems, meeting the root respiration demand, and the independent space inside the support layer can avoid the mutual entanglement and crowding of root systems.
