用二次正交旋转组合设计的方法,选择产量为目标,以播种期、播种密度为变量,对郁金的栽培技术进行了研究。结果表明,增大播种密度并推迟播种期可使郁金增产50%左右。建立的回归方程(Y=123.88+24.12X_1+30.22X_2-9.58X_1~2-16.01X_2~2)可用于产量预测及寻找最优的生产条件。
The quadratic orthogonal rotation combined design method was used to select the yield as the target. The planting techniques of tulip were studied with the sowing date and sowing density as variables. The results showed that increasing seeding density and delaying sowing could increase the yield of tulip by about 50%. The established regression equation (Y = 123.88 + 24.12X_1 + 30.22X_2-9.58X_1 ~ 2-16.01X_2 ~ 2) can be used for yield prediction and find the optimal production conditions.
