The field experiment with split -plot design was carried out to study the influences of dripping organic fertilizer (ami-no acid, fulvic acid) combined with spraying foliar manure (B, SI and compound sodium nitrophenolate) on the yield and quality of potato. The results showed that the potato yield in the treatment of dripping fulvic acid was significantly higher than that in the treatment of dripping amino acid and CK, and the yield in amino acid treatment was higher than that in CK without significant difference. The contents of starch, total sugar and protein in potato in the treatments of dripping fulvic acid or amino acid were significantly higher than those in CK, while there were no significant differences between these two organic fertilizer treatments. In comparison with the control (not spraying foliar manure), spraying foliar manure could significantly increase potato yield, quality, starch content, protein content and total sugar content, and spraying foliar silicon manure had the most obvious effect on increasing the yield and quality of potato among all treatments.%在田间条件下采用裂区试验设计,研究了滴灌施有机肥(主处理滴施氨基酸、黄腐酸)和喷施叶面肥(副处理喷施B、Si、复硝酚钠)相结合的供肥方式对马铃薯产量和品质的影响,结果表明:滴灌施黄腐酸处理的马铃薯产量显著高于氨基酸处理和对照；氨基酸处理的产量高于对照,但差异不显著；在对马铃薯淀粉含量、总糖含量、蛋白质含量的影响上,滴灌施黄腐酸和氨基酸处理均显著高于对照,2种有机肥之间不显著；与副处理对照相比,喷施叶面肥显著提高了马铃薯产量和品质以及淀粉、蛋白质和总糖含量,其中硅肥在提高马铃薯产量和品质上的效果最为明显.
