Abstract：The"garlic sprouts selenium-rich sweet potato"rotation model can effectively prevent the occurrence of soil-borne diseases of sweet potatoes and improve the economic benefits of growers.To explore the optimal planting model of garlic sprouts and the optimal frequency of organic selenium compound spraying on sweet potatoes,this experiment investigated the effects of different planting models of garlic sprouts on their yield and income,as well as the influence of the frequency of organic selenium compound spraying on sweet potatoes on their biological traits,yield and other indicators.The results showed that the net income the two-film cultivation mode of garlic sprouts was 143 976.00 yuan/hm2,and the net income of the three-film cultivation mode was 353 115.00 yuan/hm2.After spraying high-purity organic selenium compounds three times,the selenium content of sweet potatoes was 148 μg/kg,the taste score of sweet potatoes was 85 points,and the dry matter rate of sweet potatoes reached 28.6％.To sum up,the three-film cultivation model for garlic sprouts has the highest benefits,and spraying high-purity organic selenium compounds three times on selenium-enriched sweet potatoes is the best.
