摘  要:
采用二次正交回归旋转组合设计,对黔西北山区地膜覆盖栽培条件下高油玉米高产栽培综合配套技术措施进行了研究。建立起产量与种植密度及氮、磷、钾肥施用量之间的数学模型;解析了数学模型;通过计算机模拟寻优,筛选出了高油玉米高产栽培的农艺综合方案:密度62463~65633株/hm2;氮肥(纯N)312.02~359.04kg/hm2;磷肥(P2O5)303.47~345.32kg/hm2;钾肥(K2O)293.64~333.30kg/hm2。

摘  要:
The multi-quadric regressive orthogonal rotary combination design was applied in the experiment. The integrated high-yieldingcultivation technique ofhigh-oil maize covered with plastic filmin northwestern Guizhou was researched, and the mathematical model between theyield and four main cultural factors: the planting density, application amount of N, P and K was set up. Through the application of computertechnique,wehad searched and determined the optimumcompositions ofthe model in cultivation management:the plantingdensity62 463~65 633individual plants/hm2, N312.02~359.04 kg/hm2, P2O5303.47~345.32 kg/hm2, K2O293.64~333.30 kg/hm2.
