摘要： 用复合氨基低聚糖对1~4年生西洋参处理,结果表明：1年生西洋参亩株数增加1.4万株，增产34.8%；2年生增产12.8%；3年生增产16.6%；4年生增产15.7%。对西洋参立枯病防治效果达69.8%，锈腐病为61.4%，晚疫病为66.5%，黑斑病为49.5%,参根白、短而粗，商品性好，经济效益提高20%以上。

Abstract: It was observed that the yields of 1~4 P. quinquefolium were increased by 34.8%, 12.8%, 16.6% and 15.7% respectively when treated with co-amino-oligosaccharide (spraying). The prevention and control of disease on P. quinquefolium (caused by Rhizoctonia solani、Cylindro carpon、Phytophthora cactorum and Alternaria spp ) were 69.8%、61.4%、66.5% and 49.5% respectively. With the application of co-amino-oligosaccharide, the root of Panax quinquefolium was white、short and thick,. The economic benefit increased 20% when treated with co-amino-oligosaccharide. It was demonstrated that Panax quinquefolium not only increased yield but improved pathogenesis-resistance when treated with co-amino-oligosaccharide (spraying).
