摘　　要：通过研究提出塔落岩黄芪和细枝岩黄芪在内蒙古伊盟地区的适宜收获期为１０月上旬，此时采收的种子品质好，种用价值高。不同发芽床上进行的发芽率比较试验表明，沙培法和土培法明显高于水选法和硝酸钾处理法。The study indicated that the appropriate seed collecting time for Hedysalum laeve Maxim. and H. scoparium Fisch. et Mey. is the ten-day period of Octeber. The seeds collected at this have good quality and better seed use value. The tests of germination percentages on different seedbed show that sand substract and soil substract are obviously bether that water culture and potassium nitrate treatment.
