摘　　要：采用春播双膜覆盖方式,选用豫东主栽品种商马铃薯1号为试验材料,采取随机区组设计,设置7个处理,在相同施肥管理水平下,通过分析密度协迫对商马铃薯1号生物经济性状的影响,筛选出适宜豫东二季作区双膜栽培的种植密度.试验结果表明,商马铃薯1号双膜栽培适宜密度为每667 m24200~4700株,最佳密度为4200株/667 m2.Taking double-membrane mulching method in spring sowing,the density experiment of Shang Potato No.1,the main potato cultivar in east Henan,was carried out under the same fertilization management level with the random block design and 7 treatments,by analyzing the effects of density stress on the biological and economic characters of Shang Potato No.1,in order to screen out the suitable planting density under double-membrane cultivation.The results showed that the proper planting density was 4200-4700 plants/667 m2,and the optimum planting density was 4200 plants/667 m2.
