Abstract:The spatial distribution pattern and sampling technology of ginseng fruit early blight in greenhouses were studied by using spatial distribution pattern test, aggregation intensity index test and linear regression methods. The results showed that the spatial distribution pattern of ginseng fruit early blight was aggregation distribution, and the theoretical sampling model was n=3.841 6/D2(0.731 5/x¯+0.506 1).
