[0002] Dried flowers originated in Europe and are popular in Europe, America and economically developed regions. They are the embodiment of people's pursuit of the perfect art of "returning to nature" and are loved by people for their simplicity, elegance and luxury. In today's society, more and more people like to place dried flowers of different levels and specifications in the halls of their homes, on the desks in their studies, and in the halls of hotels and restaurants to decorate, embellish and beautify their lives, giving people warmth and comfort. Dried flowers are also excellent gifts for relatives and friends, transmitting feelings and friendship to each other.

[0048] Embodiment 1

[0049] S1. Harvest the leaf materials of Euonymus japonicus Thunb. that have grown for more than 2 years, and use them fresh in season. The best production time period is early spring and autumn and winter. In the remaining time, the tender tips should be removed. It is required that the leaves are densely and evenly distributed, complete without pests and disease spots; the younger the leaves, the greater the longitudinal curling degree. The old branches should be mainly harvested, and the wilting length of the tip should not exceed 5 cm; the single branch length is more than 30 cm, and the root diameter shall not exceed 0.8 cm. Wash the dirt on the plant leaf material rod with high-pressure water, which has high efficiency; remember that the leaf part cannot be scrubbed to avoid damage to the leaves; after washing, gently shake the leaf material to remove the water on the leaf surface. Do not press it when lying flat in the centrifuge, and try to reduce the damage to the leaves. Gently shake and slow down slowly, and stack them neatly for standby.

[0050] S2. Weigh the raw materials according to the following proportions: 38 kg of glycerol, 12 kg of sorbitol, 5 kg of alcohol, 1.5 kg of pigment, 0.5 kg of preservative and fungicide, 0.02 kg of disodium ethylenediaminetetraacetate, and 42.98 kg of water. First, heat 5 kg of water to 70 °C, dissolve the pigment in it to prepare a pigment solution; then add disodium ethylenediaminetetraacetate, preservative and fungicide, pigment solution, glycerol, sorbitol, and alcohol to the remaining water in sequence. Stir well after each addition of raw materials to finally obtain a bactericidal softening solution, which is reserved in a storage tank. Check the sealing condition of the pressure tank, requiring the rubber gasket to be intact, evenly pressed into the notch, and no leakage during pressure testing; check the circulating pump and hydraulic pump, requiring stable operation and all pipeline valves in a reasonable state. Put the plant leaf materials into a cylindrical basket (the cylindrical basket matches the size of the pressure tank). The plant leaf materials should be placed in the basket with the roots facing down as much as possible, evenly filled without pressing. After closing the basket, insert the pin correctly to the bottom, and lay the tail of the pin flat along the basket; open the inlet and outlet valves of the pressure tank, transfer the prepared bactericidal softening solution from the storage tank into the pressure tank by the circulating pump until the liquid level is 35 cm below the tank opening. Lift the basket filled with plant leaf materials vertically into the tank with a hoist, lower and lift it up and down 3 times to make the bactericidal softening solution evenly adhere to the leaf surface; seal the pressure tank, continue to pump the liquid medicine in the storage tank into it by the circulating pump until it is full, and then close the top exhaust port; close the inlet and outlet valves, start the hydraulic pump to pressurize, and pay attention to the sealing condition at all times during the operation. Stop the operation immediately to solve any liquid leakage problem. Pressurize the hydraulic pump to 13 kg for the first time, and then keep the pressure not less than 10 kg for 5 days. After soaking, lift the basket vertically about 10 cm above the liquid level with a hoist and drain for 30 min; lift it out of the tank opening, open the basket on the ground, take out the plant leaf materials from the basket, wash them once with clean water, pay attention not to soak, drain the water and then hang them on a cart, and place them in a cool, ventilated, dust-proof place to dry naturally, or dry them with circulating hot air until the back of more than 80% of the leaves is dry to obtain the softened plant leaf materials;

[0051] S3. Use 83 kg of water, 10 kg of FS-460 adhesive, 6 kg of polyethylene glycol with a molecular weight of 6000, and 1 kg of mildew preventive, stir and mix them in sequence to obtain 100 kg of glue solution; hold the root of the plant leaf material and immerse it in the glue solution, and brush it up and down 2 times to ensure that the leaves are completely attached with the glue solution; drain for 1 min after brushing the glue solution to let the excess glue solution flow back for reuse. Gently spin-dry the leaf materials with a spin dryer until there is no glue solution dripping from the leaves, and hang them with the roots facing down to dry in a cool and ventilated place until the surface of the leaves is dry.

[0052] S4. The plant leaf materials are pruned without shrinking or curling, the leaves do not fall off, the leaves are plump and flat like a fresh state, and the overall color is consistent. Remove the excess empty stems, select until the qualified rate is more than 90%, pack them in standard boxes, add insect repellent and store them off the ground. Those that need to be stored for a long time must be stored in a sealed warehouse. The Euonymus japonicus leaf materials prepared in this example are as Figure 1 shown.

[0053] The fidelity plant leaf materials prepared in this embodiment have been produced in dozens of tons every year since 2008, and the products are sold overseas. After being appraised by the testing agency, the chromaticity fastness of the leaf materials in this embodiment meets the standards in both dry and humid environments; moreover, the plant leaf materials in the embodiment of this application have no mildew, no brittleness, and no color change after being used for more than 3 years.
