B_9(阿拉、AIar)也叫B_(995),化学名叫N-二甲胺基琥珀胺酸,分子量160.17,结构式为:一种无臭无刺激性的植物生长调节剂。B_9能抑制植物徒长,可使植物矮壮,增加耐寒,耐旱能力,防止落花,促进结果。喷施于人参植株后有明显的矮壮作用,并能形成多茎参,产量可提高35%左右。但是群众反应留种田喷施 B_9后种
B_9 (AIAR), also known as B_ (995), is a chemical called N-dimethylaminosuccinamic acid with a molecular weight of 160.17 and is structurally an odorless and nonirritating plant growth regulator. B_9 can inhibit the growth of plants, plants can be short and strong, increase cold, drought tolerance, prevent falling, promote the results. After sprayed on ginseng plants obvious shortening effect, and can form more stems, the yield can be increased by 35%. However, the reaction of the masses to stay after spraying B_9 farming species
