摘　　要：研究不同栽培密度和不同施肥方案对陕西略阳地区雪莲果产量和品质的影响,为其高产栽培提供理论依据。设计4种密度试验和肥料试验方案,统计分析不同处理下的雪莲果田间性状和产量,测定主要成分含量。结果表明,800株/667m2的条件下生长的雪莲果单株产量、平均每个块根质量和还原糖含量最高,折合产量(kg/667m2)和低聚果糖的含量仅比最高者低9.68%和3.25%。在农家肥2 000kg/667m2的条件下,雪莲果的单株产量、折合产量(kg/667m2)和平均单果质量最大。低聚果糖和还原糖含量分别占块根干质量的53.66%和17.00%,在各处理的结果中排第2位。综合考虑,略阳地区雪莲果栽培的最佳密度是800株/667m2,最佳的施肥方案是农家肥2 000kg/667m2。Study the effect of different planting density and fertilization scheme on the yield and quality of the Smallanthus sanchifalius in Liieyang Area to provide theoretical foundation for high yield culti- vation of this plant. We designed four planting densities and four fertilization schemes, respectively and make the statistic analysis on agrinomic traits, yield and main component contents. The planting density of 800 plants per 667m2 gave the best single plant yield, average root weight and the reducing sugar contents. The yield per 667m2 and the fructooligosaccharide content are 9.68% and 3.25% low- er than that in the highest one, respectively. On the condition of using farm manure 2 000 kg per 667 m2 , the single plant yield, yield per 667m2 and the average root mass are the best. The Fructooligo- saccharide contents and reducing sugar contents account for 53.66% and 17.00% of dry root mass, respectively, which are the second in all treatments. Comprehensively, the best planting density is 800 plants per 667m2 and the best fertilization scheme is using 2 000 kg farm manure per 667m2 in Lueeyang Area.
