摘要
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。
A Method of orthogonal conic combina torial design has been employed in the study of highyield agronomic measures of C. longa. The results show that by increasing plants/mu and postponing sowing date, the yield is 50% higher than before, mathematical model of yield on plants/mu and sowing date were established, which can be used to predict the yield and explore optimal agronomic measures.
