平贝母为百合科(Liliaceae)植物平贝母(Fritillaria ussuriensis Maxim),药用干燥鳞茎。为常用紧缺中药材。我省历来靠野生采挖,提供药用,年收购量仅占需要量的2～3%。由于连年采挖,资源衰竭,产量下降。故必须变野生为家种,以逐步解决供求之间的矛盾,尽快满足医疗需要。现将我省九年来的实验结果简介如下: 一、植物分布和生活习性东北三省均有零星分布,我省主要分布于五常、尚志、阿城、延寿、饶河五县的半山区,多生长在向阳的山脚坡地阔叶林下,山间平地也偶有着生。资源颇少,密度稀疏,产量甚低。植物习性:平贝生长在半山区,具有耐寒、喜湿的特点,春季要求气候温暖,阳光充足,水分充沛;夏季要求气候凉爽,遮阴郁闭,土壤湿润的特定的小气候自然环境条 Fritillaria is the Liliaceae plant Fritillaria ussuriensis Maxim, medicinal dry bulbs. For the common shortage of Chinese herbal medicines. The province has always rely on wild excavation, providing medicinal, annual purchase only accounted for 2 to 3% of the required amount. Due to continuous mining, resource depletion, production decline. Therefore, we must change the wild for the family to gradually resolve the contradiction between supply and demand and meet the medical needs as soon as possible. Now the experimental results of our province in the past nine years are as follows: First, plant distribution and living habits of the three provinces in Northeast China have sporadic distribution, the province is mainly distributed in Wuchang, Shangzhi, Acheng, Yanshou, Rao five counties in the Mid-mountain, Under the broad-leaved forest in the sunny hillside, there are occasional students in the mountainous terrain. Few resources, sparsely populated, yield is very low. Habitat habits: flat shellfish grow in the Mid-Levels, with cold-resistant, hi wet characteristics, the spring requires a warm climate, sunny, abundant water; the summer requires a cool climate, shade, soil moist specific microclimate natural environment
