苍术为常用的中药材,在人工栽培研究中,我们发现春播苍术出苗期间正值我国北方干旱、少雨、大风和寒流频繁的季节,造成苍术出苗率极低。为此,我们采用了不同覆盖方式对苍术出苗的情况作了试验,取得了较为满意的效果,现简报如下。一、材料与方法选择成熟较好的人工栽培苍术种子在30℃的温水中浸泡16小时,于3月22日在陕西咸阳市陕西中药研究所药园内播种,设地膜覆盖、树枝覆盖(女贞子的树枝叶)和不覆盖作 Atractylodes commonly used Chinese herbal medicines, artificial cultivation in the study, we found that during the spring sowing Atractylodes Positive Emergence in northern China drought, less rain, windy and cold frequent seasons, resulting in very low emergence rate of Atractylodes. To this end, we used different methods of covering the emergence of Atractylodes tested, and achieved satisfactory results, are summarized as follows. First, the material and method selection Well-matured cultivated Cactus seeds immersed in warm water at 30 ℃ for 16 hours on March 22 in Shaanxi Xianyang City Shaanxi Institute of Traditional Chinese Medicine Park sowing, with plastic cover, branches covered (female Sadako branches and leaves) and not covered for
