摘要
试验研究了5个密度水平对淀粉加工型马铃薯品种陇薯8号农艺经济性状及产量的影响。结果表明,随着密度的增加,植株高度呈增高趋势,商品薯率呈递减趋势,密度对淀粉含量影响不明显。陇薯8号在张掖市种植的最佳密度为7.5万株/hm^2,在此密度下平均产量达62674.4kg/hm^2,单株结薯数和单株产量表现最优,其田间种植垄株距为110cm×24cm。
Experiments were conducted to study the effect of five density levels on agronomic and economic traits and yield of starch processing potato Longshu No. 8. The results showed that with the increase of density the plant height had an increasing tendency, but the marketable potato percentage had a decreasing trendency, the dengsity had no obvious effect on starch content. The optimum plant- ing density of Longshu No. 8 was 7.5 × 104 plants/ha in zhangye city, ridge distance was 110cm, plant spacing was 24cm, the yield of 7.5 × 104 plants/ha level reached 62674.4kg/ha, both the single stub tuber number and yied per plant showed better performances.
