摘　　要：[目的]为甘薯高产栽培提供理论依据。[方法]以食用型甘薯品种"冀秦薯1号"为试验材料,设置3种行距(60、70和80 cm)和3种株距(20、25和30 cm),研究不同行株距对甘薯产量及农艺性状的影响。[结果]加宽行距或加大株距均可以提高甘薯的鲜薯产量、单株鲜薯重等指标。60 cm×20 cm,60 cm×25 cm以及70 cm×25 cm这3种行株距配置甘薯的鲜薯产量均极显著高于其他6种行株距配置。当行株距为70 cm×25 cm时,单株鲜薯重最高,极显著高于其他8种行株距配置。当行株距为70 cm×30 cm和80 cm×30cm时单株茎叶鲜重极显著高于其他7种配置。[结论]行距×株距互作除了对单株结薯数无显著影响外,对其他8个性状的影响均达到显著或极显著水平。[Objective] The research aimed to provide theoretical basis for the high-yield cultivation of sweet potato. [Method] Taking edible sweet potato variety Jiqinshu 1 as test materials,three row spaces（60,70 and 80 cm） and three plant spaces（20,25 and 30 cm） were designed to study the effects of different row space and plant space on the yield and agronomic traits of sweet potato. [Result]The fresh potato yield,fresh potato weight per plant and other agronomic traits of sweet potato were increased by increasing the row space or plant space. The fresh potato yield of sweet potato with the row spaces and plant spaces of 60 cm × 20 cm,60 cm × 25 cm and 70 cm × 25 cm were significantly higher than other six treatments. When the row spaces and plant spaces were 70 cm × 25 cm,the fresh potato weight per plant was the highest,which was significantly higher than other 8 treatments. The fresh stem weight per plant of sweet potato in the row spaces and plant spaces treatments of 70 cm × 30 cm and 80 cm × 30 cm were significantly higher than other 7 treatments. [Conclusion] The interaction between row spaces and plant spaces had no significant effect on potato number per plant,but it had significant difference or extremely significant difference on other 8 agronomic traits.
