Embodiment 1
[0019] Application and preliminary optimization of sodium o-nitrophenolate
[0020] The application method of sodium o-nitrophenolate is to immerse the prepared sweet potato stem section base (below the axillary buds) in the prepared sodium o-nitrophenolate solution for 10 minutes, and then insert the stem section cutting into the seedling bed or seedling cultivation bed with culture medium. The culture was carried out in a plate, and the culture conditions such as temperature, light, and humidity were consistent with the conventional culture conditions. The concentration of sodium o-nitrophenolate is 1-20mg / L. Set four levels of 1mg / L, 2mg / L, 10mg / L, and 20mg / L. For each treatment, 100 stem segments are cut, and the germination time is counted on the 3rd day after cutting , the average number of taproots, germination rate, number of strong seedlings, and strong seedling rate were counted on the 30th day after cutting. The experimental design and results are shown in Table 1. ...
Embodiment 2
[0027] Application and Preliminary Optimization of Diethyl Hexanoate
[0028] The application method of diethyl aminoethyl hexanoate is to soak the base of the prepared sweet potato stem section (the part below the axillary bud) in the prepared diethyl aminoethyl hexanoate solution for 10 minutes, and then insert the stem section into the seedling bed or seedling tray with the culture medium For cultivation, the cultivation conditions such as temperature, light, and humidity were consistent with conventional cultivation conditions. The diethyl aminohexanoate concentration range is 1-10mg / L, and four levels of 1mg / L, 2mg / L, 4mg / L, and 10mg / L are set, and 100 stem segments are cut for each treatment, and the germination time is counted on the 3rd day after cutting. On the last 30 days, the average number of taproots, germination rate, number of strong seedlings, and rate of strong seedlings were counted. The experimental design and results are shown in Table 2.

Embodiment 3
[0035] Application and Preliminary Optimization of Naphthaleneacetic Acid
[0036] The application method of naphthaleneacetic acid is to soak the prepared sweet potato stem section base (below the axillary buds) into the prepared naphthaleneacetic acid solution for 10 minutes, and then insert the stem section into a seedling bed or a seedling tray with a culture medium for cultivation. The culture conditions such as temperature, light, and humidity were consistent with conventional culture conditions. The concentration of naphthalene acetic acid is 10-80mg / L. Set four levels of 10mg / L, 20mg / L, 40mg / L, and 80mg / L. For each treatment, 100 stem segments are cut. The germination time is counted on the 3rd day after cutting. On the 30th day, the average number of taproots, germination rate, number of strong seedlings, and rate of strong seedlings were counted. The experimental design and results are shown in Table 3.
