摘　　要：甘肃白银地区早熟马铃薯,因早春低温普遍采用地膜覆盖种植,成熟时间在7月中下旬,上市晚且效益低,而生产中零星种植的大拱棚地膜覆盖种植和小拱棚单、双垄覆膜种植,因配套大芽移栽技术,上市早且效益较好。为了弄清这几种种植模式的增收优劣,开展了系统试验研究。结果表明,5种早熟马铃薯种植模式与当地主要栽培地膜直播相比,均有明显的增收效果,不同种植模式间的增收大小顺序为:大拱棚直播>大拱棚移栽>小拱棚双垄移栽>小拱棚单垄移栽>地膜覆盖移栽>地膜覆盖直播。Affected by low temperature in the early spring,early potatoes in Baiyin region of Gansu Province were usually cultivated with plastic film mulch and harvested in the middle-end of July with low benefits because of marketing late.Other planting patterns on small scale,such as planting pre-sprouting seed pieces in plastic film tent,planting pre-sprouting seed pieces in single ridge in small plastic film shed and planting pre-sprouting seed pieces in twin-ridge in small plastic film shed achieved high benefits because of marketing early.In order to fully understand the income-increasing advantages and disadvantages of different planting patterns of early potatoes,the systematic experiments were carried out.The results showed that the five planting patterns tested had significant effects of increasing yields and incomes,compared with local cultivation pattern.The income-increasing order of the five planting patterns from high to low were:planting seed pieces directly in plastic film tent>planting pre-sprouting seed pieces in plastic film tent>planting pre-sprouting seed pieces in twin-ridge in small plastic film shed>planting pre-sprouting seed pieces in single ridge in small plastic film shed>planting pre-sprouting seed pieces in the field covered with plastic film>planting seed pieces in the field covered with plastic film.
