Abstract:

To provide a theoretical basis for normalization cultivating measures for Liriope muscari (Decne) Baily, the experimental plots were randomly divided. The biomass of leaf and root were regularly collected and measured. The yield, polysaccharide content and water lixivium were also determined after harvesting. The effects of transplanting time on the growth and development of Liriope muscari (Decne) Baily, root yield and quality were studied. The growing and developing rule of aerial part of L. muscari (Decne) Baily was similar among different transplanting time. 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 transplanted in April, grew and developed better. The fast-growing of L. muscari (Decne) Baily transplanted in April was beneficial to tillering, moreover, to increasing the root developing time. The root yield was significantly different at different transplanting time. The yield, polysaccharide content and water lixivium decreased with the retarding of transplanting time. In conclusion, the optimum transplanting time of L. muscari (Decne) Baily was from early April until early May.
