摘　　要：以中早熟品种‘费乌瑞它’和中晚熟品种‘定薯6号’为研究材料,分别在现蕾期、开花期和块茎膨大期对叶面喷施FeSO(0.2%)、ZnSO(0.2%)和FeSO(0.2%)+ ZnSO(0.2%),以清水为对照,研究喷施不同种类微量元素对马铃薯植株性状和块茎品质的影响。‘定薯6号’和‘费乌瑞它’的生育期延长,株高和茎粗与对照相比,均有不同幅度的增加。维生素C含量、淀粉含量、粗蛋白含量、干物质含量较对照增加,还原糖含量下降。2个参试品种的单株产量和商品薯率与对照相比,均有所增加,‘定薯6号’和‘费乌瑞它’的单株产量分别较对照增加了2.8%~16.0%、3.4%~11.1%。喷施铁、锌促进了马铃薯的生长,提升了品质,提高了单株产量和商品薯率。FeSO(0.2%), ZnSO(0.2%) or FeSO(0.2%) + ZnSO(0.2%) were sprayed on the leaves of mid-early maturing variety ’Favorita’ and mid-late maturing variety ’Dingshu 6’ at budding, flowering and tuber bulking, respectively,using water as control, to study the effects of spraying Fe and (or) Zn on potato plant characteristics and nutrition quality.The growth duration of ’Dingshu 6’ and ’Favorita’ was prolonged, and the plant height and stem diameter were increased to some extent compared with the control. Compared with the control, the contents of vitamin C, starch, crude protein and dry matter were increased, while the content of reducing sugar was decreased. The yield per plant and marketable tuber percentage of the tested varieties were also increased. The yield per plant of ’Dingshu 6’ and ’Favorita’ were increased by 2.8%-16.0% and 3.4%-11.1%, respectively, compared with the control. Spraying iron and zinc may promote potato growth, improve quality, and increase yield per plant and marketable tuber percentage.
