The application relates to the technical field of forestry seedling raising and ecological restoration, and discloses a root guiding type full-biodegradable tree planting bag based on hybrid material modification and application, the tree planting bag is an integrally injection molded structure, the inner wall is provided with vertical root guiding edges, and the bottom is provided with a cross-shaped easy-to-crack line; the tree planting bag is longitudinally divided into an upper structure area and a lower degradation promoting area. The upper part is composed of PBAT / PLA and hybrid materials and has high strength and weather resistance; the lower part is composed of PBAT / PPC, hybrid materials and plant fibers and has moisture absorption and rapid degradation characteristics. The hybrid material is a composite in which nano-hydroxyapatite grows in situ on the surface of attapulgite. Through the synergy of the longitudinal gradient material and the physical root guiding structure, long-term shape retention during seedling raising and rapid disintegration of the bottom after planting are realized, the problems of seedling taproot and degradation lag are solved, the degradation products can adjust the pH value of the rhizosphere soil and provide phosphorus and calcium nutrition, and the afforestation survival rate is improved.

A system for forming trunks of trees, plants, and vines into predetermined letter, word, numerical, and shape configurations having a wire assembly with a guide wire having a predetermined configuration; and a trunk of a predetermined thickness, whereby the trunk is secured to the guide wire, wherein the trunk adopts the configuration of the guide wire as it grows, thickens, and matures. The guide wire is a single continuous wire and is of a predetermined gauge to be shaped into said predetermined configuration. The configuration is a letter, letters, a word, words, a number, numbers, and / or a geometric shape, shapes. The trunk is secured to said guide wire with zip ties that are positioned separated a predetermined distance from each other allowing the trunk to align with the guide wire to adopt to the predetermined configuration.
