摘要：Quinoa is a resilient high-vielding pseudo-crop that produces grains with a balanced amino acid composition and a higher protein content than the major cereals. To explore a suitable local cultivation model in the northern part of Shanxi Province, the influence of different densities and row spacing were analyzed on the above-ground agronomic and yield characteristics. The quinoa variety 'Q1'was sown at different seeding density(6.0×104,7.5×104,9.0×104, 10.5×10*, and 12×104 plants h') and row spacings (40, 50,60, 80+40,and 90+30 cm).The results showed that the quinoa had the longest growth pe-riod and lowest lodging rate under the density of 9.0×104 plants h-1. The post-flowering chlorophyll content, stalk strength, the number of branches, and 1000-grains weight were increased first and then de-creased with increasing the planting density, highest at 9×10* plants h1 which were 24%,30%,39%, 27%.and 44% higher respectively than other den-sity. Wide-narrow row arrangement of 80+40 cm was more appropriate for lower density while uni-form row spacing of 60 cm significantly increased yield and improved canopy at optimum and higher density. It can be seen that the optimum planting density(9×104 plants h')and row spacings(60 cm)can increase the yield of quinoa.
