Abstract:

This research explored the dynamic effects of different sowing methods, different mulches, different seed dressing methods, and different fertilizer treatments on the sowing process of Fritillaria cirrhosa and Fritillaria unibracteata. The number of emerged seedlings of the two Fritillaria species seeds showed a sigmoid curve relationship with time in days since sowing for most treatments with the increase of days after sowing, and the consistency between treatments was significant. There were positive correlations between the seedling emergence rate of F. unibracteata treated with partial fertilization and the number of days after sowing. At (30±3) days after sowing, the final germination percentage for the seedlings of the two Fritillaria species had been reached, and for a given treatment the growth and development of F. cirrhosa seeds was better than F. unibracteata. It was found that drilling was better than broadcasting or ridge sowing; Covering with wheat straw was better than covering with pine needles or plant ash or sheep dung; Sowing without seed dressing was better than dressing with plant ash or sheep manure. The optimal fertilization rates for F. cirrhosa were nitrogen 2.00 g·m-2, phosphorus 4.90 g·m-2, potassium 1.25 g·m-2. The optimal fertilization rates for F. unibracteata were nitrogen nil, phosphorus 9.80 g·m-2, and potassium 2.50 g·m-2.
