To explore the effects of the distribution of biological organic fertilizer on the soil quick nutrients, nutrient yield, yield and quality. Using taro No. 5, on the basis of reducing 25% slow-release fertilizer, different biological organic fertilizer and combination were applied to determine the seedling yield, agricultural properties, yield and quality, soil biochemical properties. The results showed that the biological organic fertilizer could improve the agricultural character, seedling emergence rate, soil nutrient, yield and potato block quality of potato. The application of biological organic fertilizer could improve the content of effective nutrients in soil and adjust the pH of soil. Among them, T4 treatment had the most obvious stimulation effect, increasing by 16. 80% compared with the treatment of single sustained-release fertilizer. And the potato potato block had the highest nutrient absorption amount. In terms of quality, T4 treatment had the highest content of crude protein, starch, reducing sugar and Vc, which was 26. 97%, 51. 67%, 166. 94% and 39. 63% higher than the control, respectively. Therefore, the application of bio-organic fertilizer with slow-release fertilizer could increase the effective nutrient content in the soil and improve the yield and quality of potato in the continuous cropping area, among which the T4 treatment effect of mixed application of bio-organic fertilizer I and bio-organic fertilizer was the best.
