摘  要：
以内蒙古呼伦贝尔贝加尔针茅草甸草原为研究对象,采用正交实验设计,研究了不同水平的氮(N)、磷(P)、钾(K)配施对该地区土壤养分的影响。结果表明:土壤速效氮和速效磷含量对施肥的影响比较敏感,氮素添加会显著增加土壤速效磷含量(P<0.05);土壤全氮和全碳含量在氮肥(183kg·hm~(-2))+磷肥(350kg·hm~(-2))+钾肥(28kg·hm~(-2))处理下(N_3P_3K_2)显著高于对照和其它施肥小区(P<0.05),NPK配施土壤全钾含量显著高于NP配施(P<0.05),因此,综合施肥后土壤养分含量变化,对呼伦贝尔贝加尔针茅草甸草原进行配方施肥时应保持N肥、P肥用量,减少K肥用量。

摘  要：
The effects of applying nitrogen,phosphorus,potassic fertilizer on the soil nutrient content by using orthogonal test set fourteen processing cells in Stipa baicalensis Mowing Meadow of Hulunbeir.The results showed that soil available N and available P were more sensitive to fertilization,added nitrogen increased of soil available P significantly content(P<0.05);the soil total N and organic matter were N fertilizer(183 kg·hm~(-2))+P fertilizer(350 kg·hm~(-2))+K fertilizer(28 kg·hm~(-2))(N3 P3 K2)higher more than CK and other areas(P<0.05),NPK significantly soil total K content higher than NP combined(P <0.05).In combination with soil nutrient content of fertilization,Stipa baicalensis Mowing Meadow of Hulunbeir should keep N fertilizer,P fertilizer dosage,reduce K fertilizer dosage.
