The invention discloses a living plant modeling and grafting method with two stocks and one scion, and belongs to the technical field of plant grafting and modeling. According to the method, two stocks are symmetrically planted, wedge-shaped pressure reduction notches are formed in the outer sides of preset bending positions of trunks of the stocks, the intersection positions are in butt joint and embedded, scion supplementary grafting and trimming are conducted, and xylem healing and fusion are conducted, so that stent-free self-supporting living body modeling is achieved. The minimum diameter of the trunk of the stock can reach 0.1 cm, and the stock can be applied to multiple scenes from miniature bonsai to large garden landscapes. Bending damage of trunks can be reduced, the cultivation survival rate is increased, plant growth vigor and stress resistance are enhanced through double-root-system collaborative nutrient supply, and the method is suitable for the fields of living arches, modeling bonsai and the like and has the advantages of being stable in structure, low in maintenance cost and high in ornamental value.

The application belongs to the technical field of plant cultivation, and particularly relates to a flower accelerating hormone composition and application. The application discloses a flower accelerating hormone composition and application, which comprises 6-benzylaminoadenine, 5-azacytidine and paclobutrazol in a mass ratio of (150-200):40:(200-250). Experiments show that, after the butterfly orchid is sprayed with the preferred flower accelerating hormone composition formula, the length of the flower stalk of the butterfly orchid can be reduced by 11%-22% on average, the number of flowers can be increased by 11%-53% on average, the flowering period can be prolonged by 10-40 days, the commodity form is significantly improved, and the application method is simple and easy to popularize and apply in large-scale production.

The invention belongs to the technical field of phase change materials, and discloses a two-temperature-zone immortal flower phase change material and a preparation method thereof.The preparation method comprises the steps that fresh roses are dehydrated and bleached, and bleached roses are obtained; carrying out solvent replacement on the bleached roses by using tert-butyl alcohol; placing the bleached roses subjected to tert-butyl alcohol replacement in a polyethylene glycol / carmine pigment / tert-butyl alcohol mixed solution, and standing for reaction to obtain roses containing polyethylene glycol / carmine pigment / tert-butyl alcohol; the method comprises the following steps: freezing roses containing polyethylene glycol / carmine pigment / tert-butyl alcohol, and freeze-drying to obtain polyethylene glycol / carmine pigment / rose aerogel; loading a phase-change paraffin material on the polyethylene glycol / carmine pigment / rose flower aerogel through a vacuum adsorption method to obtain the two-temperature-zone preserved fresh flower phase-change material; according to the invention, the double-temperature-zone phase change energy storage capability of the preserved flowers is realized, so that the preserved flowers have the capability of adjusting the indoor temperature, and the application range of the preserved flowers is effectively expanded.

The utility model discloses a large -span steel structure footbridge bridge beam suspension structure relates to footbridge steel structure technical field, including main arch, suspender and deck structure. Main arch is by two sides box -shaped section arch rib and welds in the arch top and 1 / 4 cross position multiple groups of cross link and constitutes integral force structure, and suspender is rigid member, and each group contains two parallel rod members, and is hinged through the column pin and the ear plate symmetrically welded in the arch rib lower web center line and the tie beam upper flange center line, realizes the flexible connection of main arch and deck structure. The deck structure contains the framework that is composed of parallelogram section tie beam, longitudinal beam and equal interval arrangement crossbeam, and the closed box is formed to the framework upper and lower cover top plate and bottom plate, and the both sides tie beam outside is equipped with the symmetric cantilever and forms the continuous overhanging structure with top and bottom plate.
