摘 要：
通过二次回归旋转设计和相关、回归分析，研究了秦油二号在双晚茬口育苗移栽情况下，密度、施氮量、施磷量等主要农艺措施与其越冬苗情和经济性状的关系，依据秦油二号栽培措施效应数学模型，运用频率分析法寻优，得出≥３０００ｋｇ／ｈｍ２产量水平的栽培措施方案为，密度１０．８３～１４．９１万株／ｈｍ２，施Ｎ量３０８．０～３４４．４ｋｇ／ｈｍ２，施Ｐ２Ｏ５量１６０．４～１９０．０ｋｇ／ｈｍ２。

摘 要：
Through the quadratic regress rotational design and relationship analysis,regression analysis,the relationship among the plant density,the nitrogenous fertilizer,the phosphate fertilizer and the quality of rape seedling during the period of winter and major economic characters for hybrid rape Qinyou No.2 planted after double late rice was studied. The scheme of agricultural measures for yield level over 3 000kg/hm 2 were as following:density,108 300～149 100 plant/hm 2;N,308.0～344.4kg/hm 2and P 2O 5,160.4～190.0kg/hm 2;according to the mathematical model of the effect of agricultural measures and through frequency analysis optimized.
