In a randomized block design, the influence of small arch shed and different substrate types on pre-elite marketable tuber yield and total yield were analyzed. The results showed that potato minituber yield under a small arch shed was significantly higher than that of no small arch shed; marketable minituber yield of the substrate formula of wheat husk vermiculite in the ratio of 1:2 was the highest, followed by the substrate formula of sheep dung vermiculite in
