Abstract
Bulbus Fritillaria cirrhosa is a precious wild herb of Liliaceae Fritillaria which grows in Tibetan area of China. Ripe seeds and one- year bulbs of Fritillaria cirrhosa D. Don were planting materials. Sandy soils, humus soils and humus soils with the dung of Hepialidae Larvae (Lepidoptera, Hepialidae) were selected as nursery materials.The experiments were conducted at XinduqiaoTown of Kangding County (Latitude: 101°, 34'N, longitude: 30°, 03'E, altitude: 3500 m) from March to Augustin 2011. The research was aimed to select the optimum medium of productive seeding and to study on effects of different media on growth of F. cirrhosa seeding. The results were: (1) Sowing with seeds and one-year-old bulbs of F. cirrhosa, S1 (100% humus soils with dung of Hepialidae larvae) was the best nursery media for sprouting. (2) The integrated performance was considered, including transverse diameter, longitudinal diameter, the ratio of longitudinal diameter to transverse diameter, 30-grain fresh weight and 30-grain dry weight. Sowing with F. cirrhosa seeds, S1 (100% humus soils with dung of Hepialidae Laravae) was the best medium for promoting the seedlings and getting larger size of bulbs. Sowing with one-year-old F. cirrhosa bulbs, S1 (100% humus soils with dung of Hepialidae Laravae) and S2 (100% humus soils) were advantageous for the growth of plantlet bulbing and getting larger size of bulbs. Adding sandy soil to substrates or 100% sandy soil asnursery media could inhibit thegrowth of F. cirrhosa bulbs, getting better shape of F. cirrhosa bulbs.
Highlights
The cultivation of medicinal plant can effectively solve the shortage of herbal source drugs or remedies and largely reduce pressure on excess exploitation of wild herbs (WHO et al, 1993)

In this paper, based on previous studies, under the nursery mode of shed, author selected 4 kinds of media and adopt the ripe seeds and one- year-old bulbs of Fritillaria cirrhosa D.Don as plant materials to study on the effects of different media on growth of F. cirrhosa breeding bulbs.The result of this paper is to provide a research base for the industrial development of Bulbuls Fritillaria cirrhosa
Summary
The cultivation of medicinal plant can effectively solve the shortage of herbal source drugs or remedies and largely reduce pressure on excess exploitation of wild herbs (WHO et al, 1993). Germplasm resources are an important part of biological resources, and a key to success for cultivation (Srivastava et al, 1996). More than 250 species of medicinal plants are commercially cultivated on about 380,000 ha in China (Canuto et al, 2012). A key to achieve industrial development of Chinese herbal medicines is to get a suitable media. The herbs had been studied on nursery media, such as Carthamus tinctorius L. and Atractylodes macrocephala Koidz (Rao-sheng, 2011, 2010)
