Abstract

An experiment about fertilizer effect of nitrogen fertilizer,phosphate fertilizer,potash fertilizer on Emalingshu No.7 was conducted to explore the balanced fertilization technique on potato in 2011.The result indicated that,nitrogen fertilizer had a significant effect on yield,but phosphate fertilizer and potash fertilizer had not significant effect on yield;The best combination of cultural factors for Emalingshu No.7 was N 172.5、P 67.5、K 90.0 kg/hm2,and it had the optimal economic benefit.
