我们于1992～1995年进行了大面积农田上直播西洋参丰产试验，平均单产1．5Kg／m2，取得较好效果，技术经验总结如下。1．提高参床高度，增强抗旱抗涝性能。农田土有机质含量低，理化性状差，易旱易涝。为此，我们将常规的播种床高度，由20～25cm，提高到28cm以上，从而提高了抗 We conducted a large-scale field experiment of American ginseng on high-yield farmland from 1992 to 1995 with an average yield of 1.5 kg / m2 and achieved good results. The technical experiences are summarized as follows. 1. Improve the height of ginseng bed and enhance the drought and waterlogging resistance. Soil organic matter content of farmland is low, poor physical and chemical properties, drought and easy floods. To this end, we will conventional sowing bed height, from 20 ~ 25cm, increased to 28cm above, thereby increasing the resistance
