Under the traditional cultivation technology model, the potato yield is low and the quality is poor, which seriously affects the planting efficiency. The application of high yield cultivation technology in potato cultivation can significantly improve the yield and quality of potato, drive farmers to increase income and get rich, and promote the development of agricultural economy. Based on this, taking Huachi County as an example, the key points of potato high yield cultivation technology were analyzed deeply.
