摘要
为了提高马铃薯产量,改善马铃薯品质,在大田试验条件下,通过选用5种微肥与清水对照对大田马铃薯进行单因素的肥料筛选试验,结果表明:氨基酸微肥、硼砂、磷酸二氢钾、钼酸铵和硫酸亚铁可明显降低马铃薯的株高,增加马铃薯的茎粗和叶面积系数,明显提高马铃薯的单产。均可以在马铃薯生产上应用。以氨基酸微肥、硼砂、磷酸二氢钾喷施增加马铃薯的产量的效果更好,可作为马铃薯叶面肥的首选。
On condition of field an selection test Singal factor fertilizer experiment with five kinds of micronutrient fertilizer and with water as contrast test in order to increase potato yield and improve its characters. The result showed micronutrient fertilizer such as aminophenol micronutrient fertilizer, borax （Na2B4O710H20）, KH2PO4, （NH4）2MoO4 and FENO4 could decrease the plant high of potato significantly and increase the stem diameter and the leaf area index So the yield of potato could be predicted increased signiflcandy. Micronutrient fertilizer aminophenol, borax （Na2 B4 O7· 10H2 O）, KH2PO4 will be the best choice and the effect of spraying will be better.
