摘要
研究了3种不同植物生长调节剂对1～2年生西洋参的作用效应。结果表明,EF4000倍液灌溉,参根增产8％;PGR_1和PGR_2200ppm灌溉,参根增产5％～7％;PGR_1200或400ppm叶面喷施,对西洋参生长均有一定的抑制作用。
The effect of three kinds of plant growth regulators on1—2 year old American ginseng was studied.The results showed that the production of ginseng roots was increased by 8％ by irrigation with EF solution at 4000 times, and 5—7％ by PGR-1 and PGR-2 at 200 ppm. The spraying Ieaves with PGR-1 at 200 or 400 ppm had certain inhibitory effect on the growth of American ginseng.
