黄芪是重要的药用植物,也是雁北地区主要出口物资之一。我区气候凉爽,日照长,温差大,适宜种植黄芪,浑源、应县一带恒山阴坡是我国著名的“北芪”产区,产品质量极佳,畅销中外.过去,栽培黄芪时采用漫山撒种,赶羊上山踏种入土,出苗率仅二成左右,成条一般需六、七年。目前,天镇县改进栽培技术,育苗移栽,缩短了黄芪生长周期,提高了产量和品质。一、育苗:夏收后选择土质疏松、浇水条件好的水地麦茬做苗圃,及时耕翻,施足底肥。播种行宽6—8寸,穴距3—4寸,出苗率可达六、七成。苗期随浇水追硝酸铵15斤。二、移栽:苗高12—13厘米,主根15—17厘米
Astragalus is an important medicinal plant, but also one of the main export materials in Yanbei. My area is cool, long sunshine, temperature difference, suitable for the cultivation of Astragalus, Hunyuan, Ying County area Hengshan shady slope is China’s famous “Beiqi” producing areas, excellent product quality, popular at home and abroad.In the past, the cultivation of Astragalus Mountain sowing, sheep riding on the road to step into the soil, the germination rate is only about 20% into a bar generally takes six or seven years. At present, Tianzhen County improved cultivation techniques, transplanting seedlings, shorten the growth cycle of Astragalus, improve the yield and quality. First, nursery: After the summer harvest choose loose soil, good water conditions, wheat stubble water nurseries, timely tillage, Shi enough base fertilizer. Sowing width 6-8 inches, hole distance 3-4 inches, the emergence rate of up to six, Qi Cheng. Seedling with watering ammonium nitrate 15 pounds. Second, transplanting: 12-13 cm seedling height, main root 15-17 cm
