摘　　要：【目的】明确宁夏半干旱区燕麦种子生产的适宜播种量和行距,提高种子产量。【方法】课题组采用播种量(90kg·hm^(-2)、120 kg·hm^(-2)、150 kg·hm^(-2))与行距(15 cm、20 cm、25 cm、30 cm)二因素随机区组设计,探究了播种量和行距对燕麦种子产量及构成因素的影响,并利用通径分析进行评价。【结果】结果表明,播种量和行距对燕麦种子产量、单株有效分蘖数、主穗长、单穗穗重、单穗小穗数、单穗粒数、千粒重均有显著影响(P﹤0.05);且随着播种量和行距的增大,燕麦种子产量基本呈先增后降的变化趋势,其中,在播种量为120 kg·hm^(-2)、行距为20 cm时,种子产量最高,达3 145.41 kg·hm^(-2)。【结论】本次试验结果可作为宁夏半干旱区燕麦种子生产的播种量和行距配置的参考。[Objective] To determine the suitable sowing amount and row spacing for oat seed production in the semi-arid region of Ningxia and improve the seed yield. [Method] The research group adopted the two-factor random block design of sowing amount(90 kg·hm^(-2), 120 kg·hm^(-2), 150 kg·hm^(-2)) and row spacing(15 cm, 20 cm, 25 cm, 30 cm) to explore the effects of sowing amount and row spacing on oat seed yield and its components, and used path analysis to evaluate. [Result] The results showed that sowing amount and row spacing had significant effects on oat seed yield, effective tiller number per plant, main spike length, spike weight per spike, spikelet number per spike, grain number per spike and 1 000-grain weight(P<0.05). And with the increase of seeding amount and row spacing, the oat seed yield basically increased first and then decreased. Among them, when the seeding amount was 120 kg·hm^(-2)and the row spacing was 20 cm, the seed yield was the highest, reaching 3 145.41 kg·hm^(-2). [Conclusion] The results of this experiment can be used as a reference for the seeding amount and row spacing configuration of oat seed production in Ningxia semi-arid region.
