Abstract
Through the practice of balanced fertilization in this study,it was found that potato could achieve the high yield of 31845.30 kg/hm~2 and profit of 3306.90 yuan/hm~2 , the ratio of output and input reached 13.63 under the condition of applying nitrogen (N) 141.15 kg/hm~2, phosphorus (P_2O_5) 104.55 kg/hm~2 and potassium (K_2O) 198.90 kg/hm~2 with a ratio of 10.741.41(NP_2O_5K_2O). It is clear that balanced fertilization can raise the yield of potato and decrease the content of nitrate and reduction sugar as well as increase starch content and then improve the quality and economic benefit of potato. Nitrate content in potato can be increased by nitrogen application and significantly reduced by application of phosphorus and potassium. The contents of heavy metals in potato are under the level of National Food Hygiene Standard.
