迪庆青稞优化栽培数学模型研究

Study on optimize cultivation technique mathematics model of naked barley in Diqing

为了给青稞高产栽培提供依据，以迪庆主栽品种短白青稞为材料，选取影响青稞产量的基本苗、施氮量和施磷量为决策变量，通过二次正交回归设计试验及分析，结果表明：当基本苗为84．33×10^4～104．31×10^4苗／hm^2，纯氮用量在183．38—204．5ks／hm^2，P2O5的施用量在25．64—27．69kg／hm^2，产量可高于2780kg／hm^2，效益显著。

In the experiment, a regression analysis method with three unknown factors was adopted to study the naked barley yield＇ s relation. The results showed the naked barley yield would attain above 2780 kg/hm^2 when the seedling is about between 84.33 × 104/hm^2 to 104.31 × 104/hm^2 ,the nitrongen is applied about between 183.38 kg/hm^2 to 204.51 kg/hm^2 ,the P2O5 is applied about between 25.64 kg/hm^2 to 27.69 kg/hm^2 in Diqinq.
