本文采用“四元二次回归通用旋转组合设计”方法,结合大田生产示范,研究啤麦高产、稳产与其施N、P、K肥、播种量间数学函数关系,从中优选出综合的栽培组合方案———栽培模式。即啤麦平均产量稳定在6000kg/hm2以上,灌淤土类施纯N195~225kg/hm2,P2O5135~165kg/hm2,K2O105kg/hm2,氮磷比1.5∶1,播种量420~480万/hm2有效粒数。淡灰钙土类施纯N270~330kg/hm2,P2O5135~165kg/hm2,K2O105kg/hm2,氮磷比2∶1,播种量630~690万/hm2有效粒数。
In this paper, the combination of quadratic quadratic regression general rotation design method and field production demonstration were used to study the relationship between high yield and stable yield of wheat germ and their N, P, K fertilizer and sowing rates. The comprehensive combination plan was optimized --- Cultivation mode. That is, the average yield of beer barley is stable at above 6000kg / hm2, the irrigation silt soil is pure N195 ~ 225kg / hm2, P2O5135 ~ 165kg / hm2, K2O105kg / hm2, nitrogen and phosphorus ratio is 1.5:1, hm2 effective grain number. Light gray earth calcined N270 ~ 330kg / hm2, P2O5135 ~ 165kg / hm2, K2O105kg / hm2, nitrogen and phosphorus ratio 2: 1, seeding rate of 630 ~ 6900000 / hm2 effective grain number.
