摘  要：
为了解决内蒙古阴山北麓区旱作马铃薯施肥过程中存在的关键技术问题,于2006-2008年在该地区进行了198个"3414"试验,通过对结果的统计分析,将内蒙古阴山北麓旱作马铃薯土壤全氮划分为极低(<0.80 g/kg)、低(0.80～1.19 g/kg)、中(1.19～2.16 g/kg)、高(2.16～2.64 g/kg)和极高(>2.64 g/kg)5个等级,对应的推荐施氮量分别为>8.0、8.0～6.5、6.5～4.3、4.3～3.6、<3.6 kg/667m2;速效磷含量划分的5个等级分别为极低(<4.6mg/kg)、低(4.6～8.4 mg/kg)、中(8.4～20.7 mg/kg)、高(20.7～28.0 mg/kg)和极高(>28.0 mg/kg),对应的推荐施磷量(P2O5)分别为>5.7、5.7～4.0、4.0～1.5、1.5～0.6、<0.6 kg/667m2;速效钾含量划分的5个等级分别为极低(<64 mg/kg)、低(64～93 mg/kg)、中(93～161 mg/kg)、高(161～193 mg/kg)和极高(>193 mg/kg),对应的推荐施钾量(K2 O)分别为>4.2、4.2～3.2、3.2～1.7、1.7～1.2、<1.2 kg/667m2。

摘  要：
The establishment of soil nutrient abundance index is the base of soil testing and fertilizer recommendation.From 2006 to 2008,198 rain fed potato 3414 field experiments were conducted in 8 counties of North Yinshan area,Inner Mongolia.The correlation between the soil nutrient concentration and the corresponding relative yield of potato tubers in different fertility levels was analyzed,soil nutrient abundance indexes of North Yinshan area was established initially,and recommendation rates were also calculated from the fertilizer effect functions.The total soil N was classified as 5 degrees of very low(<0.80 g/kg),low(0.80-1.19 g/kg),medium(1.19-2.16 g/kg),high(2.16-2.64 g/kg) and very high(>2.64 g/kg),and the corresponding N fertilizer recommendation rates were as >8.0,8.0-6.5,6.5-4.3,4.3-3.6,<3.6 kg/667m2.Five Olsen P grades were as very low(<4.6 mg/kg),low(4.6-8.4 mg/kg),medium(8.4-20.7 mg/kg),high(20.7-28.0 mg/kg) and very high(>28.0 mg/kg),corresponding P fertilizer(P2 O5) recommendation rates were as >5.7,5.7-4.0,4.0-1.5,1.5-0.6,<0.6 kg/667m2.Five soluble K grades were as very low(<64 mg/kg),low(64-93 mg/kg),medium(93-161 mg/kg),high(161-193 mg/kg) and very high(>193 mg/kg),corresponding K fertilizer(K2 O) recommendation rates were as >4.2,4.2-3.2,3.2-1.7,1.7-1.2,<1.2 kg/667m2.
