通过设置不同追肥用量，研究了追施水溶性生物腐植酸有机肥对马铃薯产量的影响。结果表明：施用水溶性生物腐植酸有机肥后，与对照相比，马铃薯均有不同程度的增产，增幅范围为4.02%～43.51%，单株结薯数增加了0.1～1.0个/株，单株块茎重增加了0.007～0.080千克/株。叶面喷施水溶性生物腐植酸有机肥的增产效果随着用量的减少而减弱。当追肥用量为50.01 L/h m2时，为最佳经济用量，其产投比达9.95，比C K提高12.91%；继续增加用量，经济效益反而有所下降。在马铃薯现蕾期后，连续喷施水溶性生物腐植酸有机肥能起到增产、增收的效果。

The effects of water soluble bio-humic acid organic fertilizer topdressing on yield of potato was studied by designing different amounts. The results showed that after topdressing water soluble bio-humic acid organic fertilizer on potato, the yields have been increased in varying degrees (the ampliifcation raged from 4.02%~43.51%), tuber number of single plant has been increased by 0.1~1.0 ramets, tuber weight of single plant has been increased by 0.007~0.080 kg, contrast to CK. With the reducing of amounts, yield increasing effects were weakened. To achieve the best economic ef-fect, the topdressing amount should be 50.01 L/hm2, the ratio of output to input reached 9.95, increased by 12.91%, con-trast to CK. However, the economy effect decreased, if continued increasing the amount of this bio-humic acid organic fertilizer. Therefore, after potato budding stage, topdressing water soluble bio-humic organic fertilizer continuously, the effects of increasing yields and economy effects were feasible.
