Study on the Effects of Different Media on the Seeding of F. cirrhosa at Plateau

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.
