| 摘 要： | 在陇中高寒阴湿区研究大中微量元素配施对马铃薯陇薯5号NPK吸收规律的影响。研究结果表明,生育阶段不同养分在陇薯5号各器官中的分配比例不同,生育期单株氮磷钾养分吸收速率呈单峰曲线。生育前期吸收的养分主要分配在茎叶中;块茎膨大期,养分在茎叶和块茎中的分配约为8∶2;成熟期,块茎中氮磷钾的比例分别约为50%,65%,60%。出苗后45 d,65~75 d分别是马铃薯陇薯5号P、NK需求关键期。此外,NPK＋微量元素配施可以提高马铃薯块茎干物质、粗淀粉、VC、粗蛋白含量,提高马铃薯产量,说明均衡施肥可实现马铃薯稳产优质。

| Abstract: | Effects of combined application of large,middle and trace nutrient elements on nutrient uptake and tnbe quality of Longhshu No.5 potato were studied in high cold and wet condition.The results indicated that assignment proportion of main nutrient in different organs of Longhshu No.5 potato differed from growing period.Law of main nutrient element uptake rate per plant of potato during whole growing period was a single peak curve.Absorbed main nutrient element at growing prophase mainly distributed to the lea... |
