摘要
本试验以五因素五水平二次通用旋转组合设计方案研究氮、磷、钾、硼及密度对杂交油菜的增产效应，通过结果分析和微机的模拟寻优找出了亩产１２５Ｋ－ｇ及１５０Ｋ－ｇ以上适宜的施肥量和密度，为生产提供了高产栽培优化技术措施。
This experiment is use five elements,five levels and twice general rotatingcomposing,design to study nitrogen phosphorus,potassium,boron and density to the effect ofincreasing production. Through analysis and computiny simulating optimum of vesult the appropriate amount and density of fertilizer in getting rapeseed l25Kg/per.mand l50Kg/per.mand above has been found out it offers high-yield cultivating optimum technical measurein production.
