It was difficult for purple sweet potato to germinate and sprout quickly which caused the low output and efficiency in its plantation. The application of seedling technology by electric heating solved the problem effectively, which could speed up the process of sprouting for purple sweet potato seeds, and could improve its sprouting rate and seedling rate. In a word, early sowing shortened the sprouting time, then the seeding can be planted early to ensure the high yield and efficiency.
