| 摘 要： | 马铃薯是喜钾作物,对氮、钾需求量较大,对磷需求量虽然较少,但磷可促进营养生长和块茎形成以及淀粉积累。全生育期中,苗期、块茎形成与增长期、淀粉积累期肥料使用的分配比例约为1∶2∶1,块茎形成与增长期是整个生育期中需肥量最大的时期。加强测土配方施肥的研究,对改善马铃薯品质、提高马铃薯产量和节本增效具有重要意义。

| Abstract: | Potato is a kind of potassium crop,which has great demand for nitrogen and potassium.The demand of phosphorus is little,yet it could promote the vegetative growth,tuberization and starch accumulation.The distribution proportion of fertilization at seedling stage,tuberization and swelling stage and starch accumulation stage is 1∶ 2∶ 1.It has important significance to strength the research on formula fertilization by soil testing for promoting the quality and yield of potato,and decreasing cost and increasing benefit. |
