Detailed Guide to Fritillaria cirrhosa Cultivation: A Full Analysis of Key Cultivation and Management Points
When cultivating Fritillaria cirrhosa, the growing environment must be considered; areas with temperatures above 30 degrees will cause it to wither, so semi-shaded hillsides are preferable. The planting site needs to be prepared before freezing, and then sowing can begin, usually carried out from September to October. Field management should be arranged according to growth conditions; fertilization, watering, drainage and irrigation are all key, and attention should be paid to preventing and controlling pests and diseases.
Field Management of Fritillaria cirrhosa
1. Building shade frames: Fritillaria cirrhosa requires appropriate shading during its growing period. After sowing, remove the bed surface covering before seedlings emerge in spring, and build shade frames by bed for shading. Low frames are 15-20 cm high, with 50-70% shading in the first year. It drops to 50% in the second year and 30% in the third year; no more shading is needed in the harvest year. High frames are about 1 m high, with 50% shading. It is best to shade on sunny days, and open the frames on cloudy and rainy days to harden the seedlings.
2. Weeding: Fritillaria cirrhosa seedlings are delicate, so weeds should be removed frequently without injuring the seedlings; small fritillaria bulbs brought out should be immediately planted back into the soil. Each year before seedlings emerge in spring and after the stems die back in autumn, apply glyphosate once for weed control.
3. Topdressing: After the stems die back in autumn, mix humus soil and farmyard manure with 25 kg of superphosphate per mu and spread it over the bed surface to a thickness of 3 cm, then cover the bed surface with branches and bamboo tips from the shade frames to protect the fritillaria through winter; if conditions permit, apply topdressing 3 times each year.
4. Drainage and irrigation: One- and two-year-old Fritillaria cirrhosa plants are afraid of drought; especially during long clear spring spells without rain, water should be sprinkled promptly to keep the soil moist. After prolonged rain or heavy rainstorms, attention should be paid to drainage to prevent waterlogging. In hail-prone areas, hail prevention measures should also be taken to avoid breaking flower stems and fruits.
