黑膜全膜双垄栽培陇薯10号原种产量与氮磷施用量及密度的关系研究
Study on Relationship Among Potato Yield and N、P Fertilizer and Density of Double Ridge Cultivation Mulched With Black Plastic Film
摘要
Abstract
Mathematic model during the application nitrogen (X1),phosphorus (X2),planting density (X3)and the yeild of Longshu 10 (Y)had been built by the quadratic general rotational combination design. Y=48.47-2.92X12 -2.65X32 -3.91X2X3. The advanced analysis result shows that the yield is more than 30 t/hm2 is pure N 129.79~170.27 kg/hm2,P2O5 117.10~152.90 kg/hm2, 49 583~55 417 plant/hm2(row spacing 60 cm,plant spacing during 230.09~33.63 cm).关键词
