摘　　要：为筛选出适合江苏丘陵地区马铃薯高产高效栽培技术,以一级种薯中薯3号为供试材料,设置平畦(CK)、地膜平畦、垄作、地膜垄作、稻草覆盖5种栽培措施,研究不同栽培措施对春播马铃薯生育期、形态特征、干物质积累、品质和产量的影响。结果表明:覆盖和垄作均能缩短春播马铃薯的生育期,促进马铃薯生长发育,增加马铃薯的干物质积累,提高马铃薯商品率和品质;地膜垄作和稻草覆盖栽培马铃薯块茎中淀粉含量、VC、粗蛋白质含量和还原糖的含量均优于其他栽培措施;地膜垄作和稻草覆盖栽培马铃薯增产幅度较大,分别比CK增产22.79%和22.13%;稻草覆盖栽培比地膜垄作商品率提高3.33%。结论:稻草覆盖栽培更适合丘陵地区春播马铃薯生产。Zhongshu 3was cultivated under five different cultivation patterns to study the effects on growth period,morphological characteristics,dry matter accumulation,quality and yield of spring-sowing potato in hilly areas of Jiangsu Province.The coverage with straw and ridge patterns could shorten growth period,promote growth and development,increase dry matter accumulation and improve commodity rate and quality.The content of starch,Vc,crude protein and reducing sugar under ridge with plastic film and coverage with straw patterns was higher than that under other cultivation patterns.The yield-increase range under ridge with plastic film and coverage with straw patterns was 22.79% and 22.13% respectively.The commodity rate under the coverage with straw pattern was 3.33%higher than under the ridge with plastic film.In conclusion,the coverage with straw pattern with lower cost is more suitable for production of spring-sowing potato in hilly areas.
