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.
