产于我省承德地区,并一向以根入药,具有清热燥湿、解毒、安胎、止血等功能的黄芩,一直依靠挖野生资源供应国内外市场。历年来,由于不注意抚育更新,资源已频临绝迹。为了保护野生宝贵资源,满足国内外市场对黄芩的需求,从1988年以来,我们开展了黄芩野生变家种的研究。试验结果证明,在目前条件下,变野生黄芩为家种是完全可能的,不仅产量、质量有较大的提高,而且有效药物成分也超过了国家药典标准。同时家种范围也由原来的承德地区一地,扩展至中南部地区,生长期也由3年生缩短为1年生和2年生。其高产优质栽培技术要点如下:一是施足基肥,深耕土壤,与禾本科作物实行轮作。二是适时播种,确保全苗。用种子直播繁殖,春、夏、秋均可播种。在承德地区春播期宜在谷雨 Produced in the province of Chengde, and has always been to root medicine, with heat dampness, detoxification, tocolysis, hemostasis and other functions of skullcap, has been relying on digging wild resources for domestic and foreign markets. Over the years, due to lack of attention to tending and renewing, resources have come to an extinction. In order to protect wild precious resources and meet the demand of skullcap in domestic and foreign markets, since 1988, we have carried out the research on wild skullcap varieties. The experimental results show that, under the current conditions, wild Scutellaria baicalensis is the most suitable for family farming, not only yield and quality are greatly improved, but also the effective drug ingredients also exceed the national pharmacopoeia standards. At the same time, the scope of family farming expanded from the original Chengde area to central and southern China. The growth period was shortened from three years to one year and two years. The high yield and quality cultivation techniques are as follows: First, Shizujifei, deep plowing the soil, and crop rotation carried out. Second, timely sowing, to ensure that the whole seedlings. Seeds live broadcast, spring, summer, autumn can be sown. Spring sowing in Chengde area should be Guyu
