Abstract
The effect of fertilizer types on increasing potato yield was studied in the experiment.The results showed 39.6% of yield increase and 21 percentage points increase of the marketable tuber rate by increasing organic fertilizer and microelement fertilizer as compared with the only compound fertilizer.Compared with the compound fertilizer with more potassium,organic fertilizer combined with microbial fertilizer could increase the potato yield significantly and the marketable tuber rate at 6 percentage point.But the increasing range in yield was relative to the soil type,which was 10.9% in black clay soil and 32.0% in alluvial soil.
