Abstract: The area with cold and cool weather in northwest China is suitable for Lily’s growth, but the alkaline soil is an important factor to reduce’s lily yield and quality. The field experiments were conducted to examine the influences of peatmoss application and different fertilizer elements (N, P, K, Ca) on yield, photosynthetic characteristic, photosynthetic pigments content, growth index and dry matter accumulation of oriental Lilies “Sorbonne”. The results showed that the ball yield, dry weight of bulb had no significant difference under the peatmoss application treatments,but the dry/fresh ratio of bulb is reduced significantly. The production performance of “Sorbonne” including photosynthetic efficiency, leaf area index and dry matter accumulation under the fertilizertreatment without N or Ca was better than that used these, and without Por K these index were generally low. It was showed that “Sorbonne” growes well in the test area (Longde, Ningxia province) which climate condition is appropriate for lily planting. The application of peatmoss has not obvious function to improved lily yield and not have effectively improved action to alkaline soil; The excessive use of N or Ca fetilizer in alkaline soil will influence the absorption of trace elements and causing lily physiological deficiency, so the lily plangting in alkaline soil should be reasonable in order to ensure the quality and yield.
