一年生黄姜施肥技术研究

Study on Fertillizer Application Techniques of Annual Dioscoreae zingiberensis

选择氮、磷和钾3个因素,采用正交旋转组合设计,以鲜黄姜产量和净产值两个目标函数,分别研究、建立相应的回归数学模型并提出了本试验条件下,3个供试农艺因子的取值方案。

The experiment N,P and K fertilizer on Dioscorea zingiberensis were studied by setting fled parameter tests with rotational design. The selecton value of three agronomic factors were put forward by establishing regression mathematics models in the production and net value.
