摘要
为了解内蒙古马铃薯主产区阴山丘陵地区施肥状况,2008、2009年进行了农户抽样调查。结果表明:(1)内蒙古阴山丘陵地区马铃薯化肥投入总量为160.0～292.0 kg/hm2,氮、磷、钾投入量分别为101.8～195.7kg/hm2、57.2～79.4 kg/hm2、5.9～6.9 kg/hm2。(2)水浇马铃薯地氮肥投入量偏高,旱地马铃薯氮肥投入量低。(3)有机肥是氮、磷肥的次要来源,是钾肥的主要来源,其为马铃薯提供的钾肥占全部钾肥的72.2%。
Random sampling survey of farmers were conducted in 2008 and 2009 to learn the fertilization status of potato in the main potato growing areas of Inner Mongolia-the hilly country of Yinshan.The results showed：（1）The total fertilizer inputs of potato in the hilly country of Yinshan were 160.0~292.0 kg/hm2,with a dose of nitrogen（101.8~195.7 kg/hm2）,phosphorus（57.2~79.4 kg/hm2）and potassium（5.9~6.9 kg/hm2）.（2）A fertilizer dose of nitrogen in irrigated land was higher,but in arid area was lower.（3）Organic fertilizer was the main source of potassium,which provided 72.2% of the total potash of potato;It was the sub-source of nitrogen and phosphorus.
