早熟马铃薯生育期短,上市早,商品性好,经济效益高。在一季作地区早熟马铃薯宜与玉米间作套种,因前期气候冷凉,玉米苗小,地面空间大,利于马铃薯生长发育,在高温来临之前薯块基本成熟。既不影响玉米生长又多收一茬马铃薯,亩增收200～300元。1990年大同市南郊蔬菜服务中心站试种罗兰德微型种薯,7月上旬收获,平均亩产2300公斤,第二茬种植大白菜,平均亩产7500公斤,经济效益相当可观。1991年怀仁县城内村利用罗兰德隔季留种的方法,在亩收油菜120公斤地块上,7月25日种植,10月10日收获,平均亩产马铃薯1625公斤;广
Early maturing potato growth period is short, the market early, good product, high economic efficiency. Early in the season as a precocious potato should intercropping intercropping with maize, due to pre-cold weather, corn seedling small, large ground space conducive to the growth and development of potatoes, tubers mature before the advent of high temperatures. Does not affect the growth of corn and take a crop of potato, mu income 200 to 300 yuan. In 1990 Datong City, southern suburbs of vegetable service center station to test Rowland miniature seed, harvested in early July, an average of 2300 kilograms per mu, the second planting cabbage, an average yield of 7500 kilograms, the economic benefits are considerable. In 1991, the village within Huairen County, using Roland to plant seeds in other seasons, was planted on a 120-kg plot of harvesting oil for grapes, planted on July 25 and harvested on 10 October, yielding an average of 1,625 kg of potato per mu;
