在精播栽培条件下，不同基本苗密度和施氮量对啤酒大麦的产量影响表现为在一定范围内呈同向正效应，超过一定范围则产生负互作作用。而这一双向变化的过程取决于产量三要素在不同苗密度和不同施氮水平下的综合表现。作者根据建立的产量和苗密度与施氮量之间的二元二次多项式四归方程得出最大籽粒产量的苗氮最优极限组合，并根据啤酒大麦对优质的要求进行筛选，进而确立适合啤酒大麦精播高卢优质栽培要求的基本苗密度与施氮量的优化组合方案。
Under the condition of precision sowing cultivation, the effects of different basic seedling densities and nitrogen rates on the yield of beer barley showed the same-direction positive effect within a certain range, while the negative correlation occurred when the density exceeded a certain range. The process of this two-way change depends on the comprehensive performance of three factors of yield under different seedling densities and different nitrogen levels. Based on the quadratic equation of quadratic bivariate polynomial between yield and seedling density and nitrogen application rate, the authors obtained the optimum combination of seedling nitrogen and nitrogen fertilizer with the maximum grain yield, and screened according to the quality requirements of beer barley, Optimum Combination Plan of Basic Seedling Density and Nitrogen Application Requirement for High Quality Cultivation of Beer Barley.
