摘要：

研究不同种植密度对短葶山麦冬生长动态、产量及多糖的影响，以期为短葶山麦冬规范化栽培提供理论依据。采用大田随机区组试验，定期采集短葶山麦冬样品，测定各器官生长量，采收时测定产量与多糖等含量。不同密度下的短葶山麦冬地上部生长发育规律相似，均呈“先升后降再升”的发育趋势，地下部块根的生长均为“先快后缓”的生长趋势。种植密度小的地上部和地下部先期生长发育均优于高密度。种植密度对多糖含量影响极小，不同种植密度间麦冬产量存在差异。种植密度对短葶山麦冬产量起重要作用，每丛6株、每hm2种植33万丛为适宜种植密度。

Abstract:

According to the study on effects of cultivating density on dynamic growth rhythm ,yield and quality，to provide a scientific basis for standardized eultivating measures. The experimental plots were randomly devided. The biomass of leaf and root were regularly collected and measured.The yield and polysaccharide content were also determined after harvesting. The growing and developing rule of aerial part of L. muscari (Decne) Baily was similar among different planting densities. Its tendency was described as “ascending, then descending, then slowly ascending”. While, the tillering tendency was described as “fast, then slow”. The aerial and underground parts of L. muscari (Decne) Baily, which was planted in low density, grew and developed better. The effect of planting density on the yield of L. muscari (Decne) Baily was significant,but on the polysaccharide was very little. The planting density played an important role in the yields of L. muscari (Decne) Baily. The optimum planting density was 6 plants of each clump, and 330000 clumps/hm2.
