闽东南沿海炸片用马铃薯品种“大西洋”的栽培综合农艺措施研究

STUDY OF CULTURAL PRACTICES FOR HIGH TUBER YIELD OF PEOCESSING POTATO "ATLANTIC" IN SOUTH-EAST OF HUJIAN

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。

Using the quadratic regression current rotation compose design Method,effects of planting density(x 1),farm mannce(x 2),Nitrogenous (x 3),phosphate (x 4)and potatsh(x 5)on getting high yield of processing potato 'Atlantic'were analysed.The results showed that importance of hte cultural practices for yield was x 2>x 5>x 1>x 3>x 4.We obtained 345 optimization schemes of cultural practices used in high yield mathematical model and the best agronomy measure for potato production of 1550kg/667m 2 by computer simulation.The 95% believe region is 3626～3800 holes(x 1)form wannll 2243 5～2379 5kg(x 2),N 6 164～6 820kg(x 3),3 851～4 149kg,11 122～11 600kg(x 5).The agronomy measure center value is 3717 holes(x 1),231165(x 2),6 492kg(x 3),4 0kg(x 4),11 391kg(x 5).$$$$
