“永良15号”优质小麦优化栽培数学模型研究

Studies on the mathematical model of optimum plantation of“Yongliang 15”wheat

  • 摘要: 运用农业系统工程原理,采用二次回归正交旋转组合设计进行田间试验,选择栽培因素基本苗数x1、施N量x2、施P205量x3、施K20量x4为调控因子,以每hm2 产量y和盈利效益yb为目标函数,建立了“永良15号”优质小麦产量、效益和农艺措施的数学模型,经微机仿真寻优,决策出7500kg/hm2和6750元/hm2以上的栽培措施组合方案,并研究了各项农艺措施的交互作用效应,为小麦优质高产高效栽培提供科学依据。

     

    Abstract: The field experiments were carried out by using the principle of agricultural systems engineering and the modular design between quadratic regression and positive rotation,in which the factors of the density(x1),amount of fertilizer N applied(x2),amount of P205 applied(x3),amount of K2O applied(x4)were taken as the adjusting factors,and the yield(y)and benefit(yb)of per hm2,as the index function.A mathematical model,which show the relationships among the yield,benefit of wheat and the different agronomic measures,is established.After optimizing the combination among different planting measures by computer,the yield of wheat exceeds 7500kg/hm2 and the benefit exceeds 6750 Yuan/hm2 .In this article the interactive effects between different agronomic measures are also studied,which provides scientific basis for the high yield and high benefit of the wheat.
