摘　　要：通过氨基酸微肥拌种对马铃薯产量及农艺性状的研究,结果表明：6个氨基酸微肥处理较对照生育期缩短2-5 d、出苗率提高1.4%-2.8%,产量提高7.7%-34.5%;拌种浓度在7.5%-12.5%时,盛花期茎粗及株高、产量构成要素、单株产量、折合产量方面均优于对照与其他试验处理;且处理浓度为10.0%时主茎数、小区结薯量、小区产量、单株产量等调查指标表现最好,折合产量为2 619 kg/667m2,较对照增产34.5%。Effects of seed dressing by amino acid microelement fertilizer on potato yield and agronomic traits were studied. Compared to the control, the growth period of the treatments was shorten by 2- 5 days, emergence percentage increased by 1.4%-2.8% and yield increased by 7.7%-34.5%. The stem diameter and plant height at the flowering stage, yield components, yield per plant and unit area yield were all better than the control and other treatments when the concentration of seed dressing ranged from 7.5% to 12.5%. The main stem number, tuber number per plot, yield per plot and yield per plant all reached the highest when the concentration was 10.0%, with yield being 2 619 kg/667m2, 34.5% more than the control.
