Two times of seed- picking frim American Ginseng in the third and forth year can reduce 40. 5 percent of yieldsI seed-picking omly once from 3 years or 4 years Ginseng reduce 15. 7 ofr 23.1 percent of yields. As compared with CK, in the seed-picking group,the rates of high, grade Ginseng product reduce 1.5 -5.5 percent,and the dry Ginseng rates reduce 1.2 -1.4 percent ; the total amounts of amino acids in 2 times of seed -picking group and in seed -picking form 3 years Ginseng group reduce 10. 753 and 3. 137 percent.
