Study on High-yield Cultural Mathematics Model of Qian-Black-Buckwheat 1 Planted in Autumn

MEI Yan,RUAN Pei-jun,WANG Xiao-hua,ZHAO Ming-yong (Bijie district agriculture research institute of Guizhou province)  
Adopting quadratic regression universal rotary combination design experiment,taking buckwheat yield as goal,taking seeding rate of Qian-black-buckwheat 1 and application rate of nitrogen phosphorus potassium as research target,we set up mathematics model between buckwheat yield and seeding rate,application rate of nitrogen phosphorus potassium when planted in autumn.By simulated test and optimality selection,we put forward comprehensive agronomic cultivation project(buckwheat yield≥2025.00kg/hm2 or ≥2100.00 kg/hm2).
