采用二次通用旋转回归设计方法 ,研究了炸片用马铃薯品种“大西洋”的主要栽培措施(种植密度、农肥、N肥、P肥和K肥 )与产量的关系 ,结果表明 ,各参试因子对产量影响的大小程度依次排序为 :农肥 >K肥 >密度 >N肥 >P肥。经计算机模拟寻优 ,获得了高产数学模型和最佳农艺措施组合方案。 6 6 7m2 产量大于 15 5 0kg的农艺组合方案有 345套 ,其 95 %的置信区域是 :密度36 2 6～ 380 0穴 ,农肥 2 2 4 3 5～ 2 379 5kg ,N肥 6 16 4～ 6 82 0kg ,P肥 3 85 1～ 4 14 9kg ,K肥11 12 2～ 11 6 11kg。农艺措施的中心值是 :密度 3717穴 ,农肥 2 311 5kg ,N肥 6 4 92kg ,P肥 4 0kg ,K肥 11 39kg。
The quadratic universal rotation regression method was used to study the relationship between the main cultivation methods (planting density, fertilizer, N fertilizer, P fertilizer and K fertilizer) and the yield of the potato variety “Atlantic”. The results showed that all the test factors The order of magnitude of impact on yield is: Farming fertilizer> K fertilizer> density> N fertilizer> P fertilizer. Optimized by computer simulation, a combination of high yield mathematical model and the best agronomic measures was obtained. There are 345 sets of agronomic combination programs with the yield of more than 1550kg. The confidence level of 95% is 3626 to 3800, 2240 to 2759 kg of agricultural fertilizer, 616 to 4 kg of N fertilizer, 6 82 0kg, P fertilizer 3 851 ~ 4 14 9kg, K fertilizer 11 12 2 ~ 11 6 11kg. The center value of agronomic measures is: density of 3717, 2 311 5 kg of agricultural fertilizer, N fertilizer 6 4 92kg, P fertilizer 40kg, K fertilizer 1139kg.
