摘  要:
为了解高产优质油菜品种的需肥特性,采用混合均匀设计,以中油杂11为试验材料,研究5种肥料配比对油菜子产油量和蛋白质产量的影响,并通过模拟寻优探讨最优肥料组合。结果表明,5种肥料与单位面积产油量和蛋白质产量的回归方程显著性概率分别达到0.039 3,0.043 7。不同肥料对产油量的影响顺序为N(x1)>P2O5(x2)>Zn(x5)>K2O(x3)>MgO(x4),对蛋白质产量的影响顺序为Zn(x5)>N(x1)>K2O(x3)>P2O5(x2)>MgO(x4)。获得产油量≥1 206 kg.hm-2和蛋白质产量≥604 kg.hm-2的适宜施肥量为氮243.14~245.26 kg.hm-2、磷153.84~154.56 kg.hm-2、钾130.66~132.38 kg.hm-2、镁8.45~8.73 kg.hm-2、锌4.00~4.16 kg.hm-2。

摘  要:
A field experiment was carried out by using mixed-uniform design to study the possible effect of 5 elements N,P,K,Mg and Zn on oil and protein yield of rapeseed,and then to establish an appropriate fertilizer combination via comput-er simulation.The results showed that the prominent probability of regression equation of fertilizer with oil and protein yield,was 0.0393,0.0437 respectively.The influencing sequence on oil yield was N(x1)>P2O5(x2)>Zn(x5)>K2O(x3)>MgO(x4),that on protein yield was Zn(x5)>N(x1)>K2O(x3)>P2O5(x2)>MgO(x4).To achieve oil above 1 206 kg.hm-2 and protein above 604 kg.hm-2,the optimum fertilizer rate was N 243.14~245.26 kg.hm-2,P2O5153.84~154.56 kg.hm-2,K2O 130.66~132.38 kg.hm-2,MgO 8.45~8.73 kg.hm-2,Zn 4.00~4.16 kg.hm-2.
