Studies on Techniques of Fertilizering American Ginseng Paper one Study on Effect of Fertilization on Yield of American Ginseng

本文对西洋参施用磷、钾、锌、硼、抗生菌肥（５４０６）的增产效果进行了研究．结果表明，采用科学的施肥方法，可显著增加西洋参产量，各种肥料配合施用可增加西洋参产量８８．７％，抗生菌肥较对照区增产３３．８％．病害发生率较其它处理降低７０％左右，对西洋参黑斑病有明显的防治效果．

We have made a study on the effect of applying P,K,Zn,B fertilizer and fertilizer of antibiosic bacterium (5406) on yield of American ginseng.This study shows that by scientific way of fertilization,the yield will be distinguishedly increased.By mixing all these fertilizers,the yield will increase by 88.7%.Fertilizer of antibiosic bacterium has a great effect on the yield. It can make the yield increase by 33.8% and most important of all,it can decrease the occurence of blight by 70%.It can prevent and cure the disease of black spot of American ginseng.
