摘要: 【目的】明确内蒙古阴山丘陵地区燕麦籽粒获得高产的最适播期和最佳养分栽培管理措施。【方法】采用311-A最优回归设计,在不同播期下,结合不同施氮量和施磷量处理,以裸燕麦白燕2号为试验材料,建立播期、施氮量和施磷量3个因素与产量的多项式回归模型。【结果】不同处理对燕麦籽粒产量影响差异显著,播期、施氮量和施磷量3个因素中,对燕麦籽粒产量影响的顺序依次为播期>施氮量>施磷量。【结论】通过对燕麦籽粒产量寻优得出,燕麦在播期为6月7日,施氮量和施磷量分别为43.69 kg/hm2和78.00 kg/hm2时,籽粒产量达最大3 197.04 kg/hm2

Abstract: 【Objective】To clarify the optimal sowing date and optimal nutrient cultivation and management measures for high yield of oat grains in Yinshan Hilly Area of Inner Mongolia.【Methods】Using 311-A optimal regression design,under different sowing periods,combined with different nitrogen and phosphorus treatments,and Baiyan NO.2 as the experimental material to establish a polynomial regression model of the three factors of sowing date,nitrogen application and phosphorus application and yield.【Results】The effects of different treatments on oat grain yield were significantly different.Among the three factors of sowing date,nitrogen application and phosphorus application,the order of impact on oat grain yield was sowing date>nitrogen application>phosphorus application.【Conclusion】By optimizing the grain yield of oat,the maximum grain yield of oat reached 3 197.04 kg/hm2 when the sowing date of oat was June 7,and the nitrogen and phosphorus application amounts were 43.69 kg/hm2 and 78.00 kg/hm2,respectively.
