摘要
通过田间氮钾化肥种类配合试验,研究不同氮钾肥种类对冬种马铃薯产量、合格薯率和效益的影响。结果表明:在每667 m2施用有机肥600 kg作基肥,化肥氮磷钾肥分别为13、7.28、25.38 kg的基础上,尿素和硫酸钾是较适宜的氮肥和钾肥种类,其总产、商品薯产量、商品薯率和经济效益分别达到3 736 kg、3 483 kg、93.24%和6 700元。
Through the combining experiment with different types of nitrogen and potassium fertilizers in the field,the effects of different kinds of fertilizers on the winter potato production,marketable potato rate and economical profit were studied.The results showed that when applying 600 kg poultry manure as basal manure,and 13 kg,7.28 kg and 25.38 kg of chemical nitrogen（N）,phosphate（P2O5） and potassium（K2O） fertilizer per 667 m2,respectively,urea and potassium sulfate were the more suitable types of nitrogen and potassium fertilizer,with which the total yield,marketable potato yield,marketable potato rate and economical profit could reach 3 736 kg,3 783 kg,93.24% and 6 700 RMB Yuan,respectively.
