川贝母种子在高原产区的繁殖研究

Study on Seed Propagation of Fritillariae Cirrhosae in Plateau Production Area

目的：寻求川贝母在高原地区种子繁殖所需求的最佳条件，总结出人工培植的最佳时间和方法。方法：利用当地的牛粪腐殖土和小拱棚对川贝母苗床进行处理。结果：川贝母种子经保湿储藏发育成熟后，经不同播种期试验，以次年3月初播种效果为最好，盖度试验以1cm牛粪腐殖土为最好。每年设施农业内生长期达到160天，自然条件下每年生长期为50～60天。结论：利用塑料大棚在以腐殖土为基质的土壤中，采用遮阳网遮阳，喷雾保湿大面积繁殖川贝母，能有效延长川贝母生长期，提高1年生小鳞茎保有率，提高川贝母产量。

This study was aimed to find the optimal conditions for seed propagation of Fritillaria cirrhosa in the plateau region in order to summarize the best sowing time and method of artificial propagation. Seeds were stored in appropriate environment. After the seeds matured, the seedbed of F. cirrhosa was treated with cattle dung humus and small shed. The results showed that early March is the best sowing time and cattle dung humus with a thickness about 1 cm is the best coving for propagation of F. cirrhosa; the growing period of film propagation （FP） is about 160 days each year compared with that of control about 50-60 days, respectively. It was concluded that the propagating seeds in plastic greenhouses by using cattle dung humus as planting substrates, using sunshade nets for shading and keeping humidity by spraying can effectively prolong the growing period, improve the retention rate of annual bulbs and the production of F. cirrhosa.
