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芹菜根腐病病株空间分布型及其抽样技术。结果表明,芹菜根腐病病株空间分布型呈聚集分布,其理论抽样模型为n=3.8416/D2(0.6755/^(-)x+0.2953)。
The spatial distribution pattern and sampling technology of celery root rot 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 celery root rot was aggregation distribution,and the theoretical sampling model was n=3.8416/D2(0.6755/^(-)x+0.2953).
