摘　　要：研究旱地马铃薯覆膜时期与种植方式对土壤湿度、产量的影响,结果表明:同一覆膜时期的沟侧栽培土壤含水量、水分利用效率、产量均高于垄侧栽培;同一位置种植的秋覆膜栽培土壤含水量、水分利用效率、产量均高于顶凌覆膜和播前覆膜;秋覆膜沟侧栽培较秋覆膜垄侧栽培、顶凌覆膜沟侧栽培分别增产7.0%、20.6%。The study was conducted on effects of different film-covering periods and different planting patterns on dryland potato.The results showed that soil moisture,water use efficiency and yield in furrow side of the furrow cultivation were higher than the ridge side of the culture in the same period.Those covered by autumn Film were higher than those by soil thawed film and film before planting at the same location in early spring.Especially,in the furrow cultivation in autumn could increase yield,compared with the ridge side of the culture in autumn and in early spring covered by soil thawed film,with 7.0% and 20.6%,respectively.
