西洋参引种在我国获得成功,已在大范围内进行推广。因自产种子不足,严重影响着西洋参生产的进一步发展。为了提高种子的自给能力,加速西洋参的发展速度,我们用高锰酸钾溶液喷施西洋参的开花植株,起到了促进西洋参种子成熟的作用,现将结果报告如下。一、试验方法试验地设在陇山东坡陕西陇县关山蛮子沟,该地海拨1950米,年平均气温5.9℃,降水量777毫米,无霜期110天左右,属亚高山草甸自然景观。苗床基质为棕壤森林腐植
Introduction of American ginseng in our success, has been widely promoted. Due to lack of self-produced seeds, seriously affecting the further development of American ginseng production. In order to improve seed self-sufficiency and speed up the development of American ginseng, we spray the flowering plants of American ginseng with potassium permanganate solution and play a role in promoting the ripening of American ginseng seeds. The results are reported as follows. First, the test method Experimental ground located in the Longdong Shan Longxian Guanxian Manzi ditch, the altitude of 1,950 meters, the annual average temperature of 5.9 ℃, precipitation 777 mm, frost-free period of about 110 days, is a subalpine meadow natural landscape. Seedbed matrix is brown soil forest
