摘　　要：试验以3个不同成熟期类型马铃薯品种为供试材料,设4个播期处理,研究云南秋作区播期对不同熟期马铃薯品种的生育期、产量、产量构成及总产值的影响,为不同品种的合理播期提供依据。结果表明:‘云薯505’适宜播期为7月中旬,‘丽薯6号’为7月中旬到8月上旬,‘云薯401’为7月中旬到8月初。如以追求产值最大化为目的,3个品种均建议尽早播种。An experiment was conducted with three varieties and four seeding dates,in order to exploring the effects of seeding date on potato growth period,yield,yield components and total value of out-put,and providing theoretical basis for the suitable seeding date of autumn potato in Yunnan. The results showed that the suitable seeding date of‘Yunshu 505’is the middle of July,‘Lishu 6’is the middle of July to early of August,‘Yunshu 401’is the middle of July to the beginning of August. When pursuing the maximizi output value,the three varieties were advised to seeding early.
