| 摘 要： | 为优化马铃薯氮、钾肥运筹,提高产量和商品薯率,2009年进行在施肥总量一定的情况下,马铃薯氮、钾肥不同时期不同比例配合施用的试验。结果表明,不同氮、钾肥运筹对马铃薯生育期影响较小,但对马铃薯经济性状和产量影响较明显,优化氮、钾肥运筹,能有效改善经济性状和提高产量,采用氮40%作基肥、40%作齐苗肥、20%作现蕾肥,钾60%作基肥、40%作现蕾肥时效果最佳,马铃薯综合经济性状和商品性好,产量最高。

| Abstract: | To study the nitrogen and potassium fertilizer operation optimized,and their yield and quality of potatoes increased,assistant utilization of nitrogen and potassium fertilization of different time and proportion were conducted when total of fertilizations were controlled in 2009.The results indicated that the growth periods of potatoes affected were smaller at the different nitrogen and potassium fertilizer operation,but economic characters and yield of potatoes were remarkably affected,and could increase and improve their economic characters and yield by optimized the nitrogen and potassium fertilizer operation.The best conditions obtained from the preliminary tests for economic characters and their yield and quality of potatoes were:basic fertilizer of nitrogen,40%;seedling fertilizer,40%;flowering fertilizer,20%,basic fertilizer of nitrogen,60%;flowering fertilizer,40%. |
