定边县地处毛乌素沙漠与陕北丘陵沟壑区的过渡地带,土层深厚、土质沙壤、高寒干冷、凉爽宜人、光照充足、昼夜温差较大,非常适合马铃薯的生长发育。经过多年试验、示范和繁殖推广,选择出了多个适合当地栽培的优良品种,总结出了一套集起垄栽培、覆膜集雨保墒、机械化播种作业为一体的旱作马铃薯栽培技术措施。栽培技术.选地整地,施足基肥选择地势平缓、土质疏松、肥力中等的沙(绵)壤地块作为马铃薯的种植田块。前茬作物以非茄科作物为宜,
Dingbian County is located in the transitional zone between the Mu Us Desert and the hilly and gully regions of northern Shaanxi. The soil layer is deep and sandy soil with cool, cool, cool and pleasant climate with abundant sunlight and large temperature difference between day and night, which is very suitable for the growth and development of potato. After many years of experiments, demonstrations and breeding programs, a number of excellent cultivars suitable for local cultivation have been selected. A set of technical measures for cultivation of dry potatoes has been summed up as a set of cultivation techniques combined with ridge cultivation, plastic film mulching and moisture preservation and mechanized sowing. Cultivation techniques.Collectively site preparation, application of foot-based fertilizer to choose flat, loose soil, moderate fertility of sand (cotton) soil plots as potato planting plots. Crops before the non-Solano crops is appropriate,
