摘要： 以“蓉紫芋5号”为材料,在川中丘陵区旱地灌1水条件下,设不灌水、出苗期、现蕾期、开花期、成熟期灌水等5个处理,研究灌水时期对紫色马铃薯产量和花青素含量的影响。结果表明：与不灌水处理相比,灌水处理提高了紫色马铃薯叶面积系数、单株干物质积累量和块茎干重及鲜薯产量。其中,现蕾期灌水产量较对照提高了22.68%～37.50%,开花期灌水产量较对照提高了26.82%～38.79%,且开花期灌水处理块茎质量分级中<30 g的比例较低,>75 g的比例较高。块茎花青素含量表现为随生育期的推进先降低后升高的趋势。不同年际间,均以出苗期灌水处理块茎花青素含量最高。因此,在仅灌1水条件下,现蕾期或开花期灌水可获得较高鲜薯产量,而出苗期灌水块茎花青素含量较高。

Abstract: To study the effects of irrigation stage on yield and anthocyanidin content of purple potato in hilly area of central Sichuan basin under the condition of once irrigation, purple potato variety‘Rongziyu 5’was used as test material and five irrigation stage treatments such as non-irrigation, seedling stage irrigation, bud stage irrigation, flowering stage irrigation and harvest stage irrigation were set in this experiment. The results showed that: compare with non-irrigation treatment, irrigation treatment increased the leaf area index (LAI), dry matter accumulation amount, tuber dry weight and fresh tuber yield. Among them, the yield of bud stage irrigation treatment was 22.68% to 37.50% higher than that of control while the yield of flower stage irrigation treatment was 26.82% to 38.79% higher than that of control. In the tuber classification of flower stage irrigation treatment, the percentage of less than 30 g was lower while the percentage of more than 75 g was higher. The anthocyanidin content of potato tuber showed a tendency of decrease first and then increase with the development of crop growth. The anthocyanidin content of seedling stage irrigation treatment was the highest in different years. Therefore, under the condition of once irrigation, bud stage irrigation or flowering stage irrigation could obtain higher fresh tuber yield while seedling stage irrigation could obtain higher tuber anthocyanidin content.
