Effects of Fertilization Treatments on the Growth of Fritillaria cirrhosa D. Don Bulbs

Abstract

Bulbus Fritillaria cirrhosa D. Don (BFC) is a rare wild herbaceous plant of Liliaceae that is commonly found in the Tibetan area of China. The bulb of F. cirrhosa is not only used for pharmaceuticals, but also as seeding materials. Two different fertilizers were applied under two different seedling substrates to study the effects of the fertilizers on the growth of F. cirrhosa bulbs. Seedlings and one-year-old bulbs of F. cirrhosa were two kinds of seedling materials. The results were: 1. The application of these two fertilizers could both enhance the preservation rate of bulbs. 2. When sowing seeds with meida A2 (100% humus soil) and A3 (50% humus soil+50% sandy soil), the application of 60 g•m-2 fertilizer T2 (three-nutrient compound fertilizer, N: P: K=17: 8: 15) could provide the one-year-old bulbs of F. cirrhosa with high yield and quality. 3. When sowing one-year-old bulbs with media A1 (100% sandy soil), A2 (100% humus soil), and A3 (50% humus soil+50% sandy soil), the application of 60 g m-2 T2 could provide two-year-old bulbs of F. cirrhosa with high yield and quality. From the data, we concluded that A2 (100% humus soil) and A3 (50% humus soil+50% sandy soil) supplemented with fertilizers such as three-nutrient compound fertilizer (N: P: K=17: 8: 15) can serve as excellent growing substrates of F. cirrhosa bulbs.
