Description

Technical Field

[0001] This utility model relates to the technical field of protective netting devices, specifically a windbreak and sand-fixing protective netting device for planting tamarisk. Background Technology

[0002] Tamarix, or tamarisk, is a tree belonging to the genus Tamarix in the family Tamarixaceae. In spring, racemes emerge laterally from last year's twigs, while in summer and autumn, racemes arise from the tips of current-year branches. The pedicels are slender, and the petals are ovate-elliptic or elliptic. The capsule is conical. The leaves are bright green, awl-shaped or ovate-lanceolate, with a keel-like projection on the back and an inwardly curved apex. Flowering occurs from April to September. Tamarix is ​​now known as the "Three Spring Willow" because it blooms three times a year. It is believed to have medicinal properties, including dispelling wind and cold, relieving exterior symptoms and coughs, promoting rash eruption, and eliminating wind and dampness. With its slender, graceful branches and beautiful red flowers, tamarisk is often planted as an ornamental plant in gardens. Tamarix is ​​a salt-secreting plant that can excrete absorbed salt. The excreted salt crystals fall to the ground, dry after being exposed to water, and form a hard "shell" that can resist wind and sand. Although tamarisk has a certain degree of drought and wind and sand resistance, it is relatively fragile in the seedling stage. Therefore, protective netting is used to protect tamarisk when it is planted.

[0003] However, most existing protective netting devices are not convenient for quick disassembly and are not convenient for combining and installing multiple sets of protective netting, making them impractical.

[0004] To address the aforementioned issues, a windbreak and sand-fixing protective netting device for planting tamarisk is proposed. Utility Model Content
