引种试验结果表明，从庄浪县引进的马铃薯品种河薯３ 号在会宁县不同生态区域种植表现中晚熟，生长势强，整齐度高，分枝部位低，结薯集中，食味好；留苗４．５０ 万～４．６５ 万株／ｈｍ ２ 时，单株平均产量为０．８８ ｋｇ，大薯率６８．１９％ ，中薯率２０．４５％ ，小薯仅占１１．３６％ 。在１９９４～１９９７ 年４ ａ多点试验、示范中，河薯３ 号均比对照品种明显增产，且抗旱、抗病、耐贮藏，现已成为会宁县和邻近地区推广种植的主要优良品种。 The results of the introduction experiment showed that the potato cultivar “Heshu 3” introduced from Zhuanglang County showed late-maturing planting performance in different ecological regions in Huining county. It had strong growth potential, high regularity, low branching position, concentrated tubers and good taste. From 450,000 to 46,500 plants / hm 2, the average yield of single plant was 0.88 kg, the rate of potato was 68.19%, the rate of middle potato was 20.45%, and that of potato was only 11.36%. In the multi-point trial and demonstration of 4 a from 1994 to 1997, the yield of Heshu 3 was significantly higher than that of the control varieties, and it was drought-resistant, disease-resistant and storage-resistant. Now it has become the main fine variety for promoting planting in Huining and its neighboring areas.
