Abstract:
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)(N3P3K2)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.
