据了解,日本中药材的消耗量与年俱增。1974年使用消耗量为7.094吨,到1983年已高达17.448吨。1986年全国普查,共使用中药计390种,其中植物药占92.6％。由于这些中药80％靠进口,所以引种栽培在日本受到高度重视。1986年1月在科学城筑波建造了一座耗资数百万美金的药用植物资源贮藏库。现已贮藏了国内外1,500种药用植物的种子。该库实际上可储三万粒种子。种子分贮于超长室(-10—20℃,保存期10—20年),长期室(1℃,保存期5—10年),短期室(10℃,保存期1—5年)。尚有种苗室(0—10℃),发芽室,恒温干燥室(20—25℃)等。日本目前栽培主要的药用植物有黄连(1975年不到200公顷,1984年已达900公顷,为全国栽培面积最 It is understood that the consumption of Japanese herbal medicine increased year by year. Consumption in 1974 was 7.094 tons, up to 17.448 tons in 1983. The 1986 national census used a total of 390 Chinese medicines, of which 92.6% were botanicals. Since 80% of these traditional Chinese medicines are imported, the introduction and cultivation are highly valued in Japan. In January 1986, a multi-million dollar repository of medicinal plant resources was built in Tsukuba, Science City. Has now stored 1,500 kinds of medicinal plant seeds at home and abroad. The library can actually store thirty thousand seeds. Seeds are stored in extra-long compartments (-10-20 ° C, shelf life 10-20 years), long-term compartments (1 ° C, shelf life 5-10 years), short-term compartments (10 ° C, shelf life 1-5 years). There are seed room (0-10 ℃), germination room, constant temperature drying room (20-25 ℃) and so on. The main medicinal plants currently cultivated in Japan are Coptis (less than 200 hectares in 1975 and 900 hectares in 1984, the most cultivated area in the country
