摘要
采用空间分布型检验、聚集强度指标检验和线形回归方法,研究了设施育苗辣椒早疫病病株空间分布型及其抽样技术。结果表明,辣椒早疫病病株空间分布型呈聚集分布。建立了理论抽样模型。
The spatial distribution pattern and sampling technology of pepper 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 pepper early blight was aggregation distribution,and the theoretical sampling model was established.
