Specifically, the following steps are included: Step S100: preparing medicine according to preset components and proportions to form a seedling-growing solution; Specifically, the seedling liquid is configured with preset components and ratios of 150 to 200 ppm pentanediol solution, 1 to 1.5 g / L urea, 0.5 to 0.8 g / L potassium dihydrogen phosphate, 1 to 2 g / L salicylic acid, 0.1 to 0.5 g / L alcohol, 0.3 to 0.6 g / L acetic acid, and 0.2 to 0.4 g / L plant ash. In actual operation, 1 to 1.5 g / L urea, 0.5 to 0.8 g / L potassium dihydrogen phosphate, 1 to 2 g / L salicylic acid, 0.1 to 0.5 g / L alcohol, 0.3 to 0.6 g / L acetic acid, and 0.2 to 0.4 g / L plant ash are added to the 150 to 200 ppm pentanediol solution to form the seedling liquid.

[0023] Step S200: inserting the groundwood branches partially upside down and immersing them in the seedling-raising liquid; More than three quarters of the top of the branch is immersed in the solution upside down, and the branch wound is suspended above the liquid surface of the seedling solution, preferably inclined at a 45-degree angle to the horizontal plane of the seedling solution to increase the light-receiving area of ​​the groundwood branch.

[0024] Step S300: aerating the seedling-raising liquid by mixing air and water according to the first preset time period. The air-water mixing pump is added to the seedling-raising liquid and turned on for 24 hours; Step S400: supplementing light to the branches of the Chinese hollyhock plant soaked in the seedling-raising liquid according to a second preset time period; The branches of the groundwood are placed in a sealed container and placed under a lamp for 24 hours for supplementary lighting. Therefore, the container is a transparent material container, that is, preferably a transparent light-transmitting material.

[0025] Step S500: Add auxin to the seedling solution according to the third preset time period and switch to natural light mode for cultivation; the third preset time period can be 10 to 15 days, and the added auxin is indolebutyric acid. Specifically, after 10 to 15 days, when the branches grow out of the water surface under the guidance of light, 150 to 300 mg of indolebutyric acid is added to each liter of solution, and the light is switched to 12 hours of cultivation or cultivation under natural light.

[0026] Step S600: After the root system of the local ash branch grows to a first length, the part of the local ash branch immersed in the seedling liquid is taken out and transferred to atomization spraying culture, and the first length is 3 cm. That is, after the root system of the local ash branch grows to a length of 3 cm, it is taken out and transferred to the part under water in the water insertion stage buried in a loose breathable matrix for 24 hours of atomization spraying culture.

[0027] Step S700: Gradually reduce the water supply according to the fourth preset time period to make it adapt to the natural soil environment before transplanting. The fourth preset time period is 5 days. That is, after 5 days, transfer to the greenhouse for seedling training, gradually reduce its water supply to make it adapt to the natural soil environment, and then transplant it.

[0028] The present invention inserts the branches of the groundwood upside down into the liquid medicine with an air-water mixing pump for rooting and seedling cultivation, effectively avoiding infection caused by the wounds of the branches contacting the water body. This solution does not need to be treated by leaf removal due to water shortage. It uses the light-chasing characteristics of the plant to make the ends of its branches chase the light and grow out of the water for rooting treatment. Since it has a large rooting area and uses the stems of the branches as a substitute for the main roots, the seedlings grow strong and have strong stress resistance after seedling cultivation.

[0029] More specifically, the method includes two parts: liquid preparation and specific operation, wherein: Preparation of seedling solution: Add 1 to 1.5 g urea, 0.5 to 0.8 g potassium dihydrogen phosphate, 1 to 2 g salicylic acid, 0.1 to 0.5 g alcohol, 0.3 to 0.6 g acetic acid, and 0.2 g to 0.4 g wood ash to each liter of 150 to 200 ppm pentanediol solution.

[0030] Operation: More than three quarters of the top of the ground beech branch is immersed in the seedling medicine solution upside down, and the wound of the ground beech branch is suspended above the water surface of the seedling medicine solution, preferably tilted at 45 degrees to the horizontal plane to increase the light-receiving area of ​​the ground beech branch. Add an air-water mixing pump to the water body and turn it on for 24 hours, then seal the container and place it under the lamp for 24 hours of light cultivation. The container is preferably made of transparent and light-transmitting material.

[0031] After 10 to 15 days, when the branches of the groundwood grow out of the water, add 150-300 mg of indolebutyric acid per liter of liquid medicine, and change the light to 12 hours of cultivation or rely on natural light cultivation. When the root system grows to 3 cm in length, take it out and bury it in a loose breathable matrix. During the water insertion stage, the underwater part is sprayed with mist for 24 hours. After 5 days, transfer it to the greenhouse for seedling training. Gradually reduce its water supply to adapt it to the natural soil environment before transplanting.
