摘要
为筛选出适宜定西旱作区推广的富锌马铃薯品种,以陇薯7号为对照品种,在垄上微沟栽培模式下对不同富锌马铃薯品种进行了比较试验。结果表明,陇薯14号折合产量最高,为28838.0 kg/hm^(2),较对照品种陇薯7号增产2.2%,陇薯12号、定薯3号、陇薯11号分别较对照品种陇薯7号减产1.5%、9.9%、10.0%。陇薯14号生育期田间长势强,单株结薯数、单株薯重、商品薯率等综合性状优良,适应性好,薯块含锌量高,是定西旱作区适宜推广种植的富锌马铃薯品种。
In order to screen out zinc-rich potato varieties suitable for promotion in dryland area,a comparative experiment was conducted on different zinc-rich potato varieties with Long Potato no.7 as the control under ridge micro-furrow cultivation mode.The results showed that the yield of Long Potato 14 was the highest(28838.0 kg/hm^(2)),which increased by 2.2%in comparation with Long Potato 7,and the yield of Long Potato 12,Ding Potato 3 and Long Potato 11 was decreased by 1.5%,9.9%and 10.0%,respectively,compared to that of control.Long potato no.14 is a zinc-rich potato variety suitable for promotion and planting in Dingxi dry farming area,with strong growth in field,excellent comprehensive characters such as number of tubers per plant,tuber weight per plant and commodity tuber rate,and good adaptability.
