Studies on Spatial Disribution and Sampling Technique of Jun-jujube Black Spot Disease in Southern Xinjiang
摘要
Abstract
Black spot disease is a kind of new fungal disease w hich happened to Jun-jujube in sou-then Xinjiang .In order to reveal the spatial distribution of the disease ,the spatial distribution pat-tern was studied by using aggregation index method and linear regression method .The results in-dicated that its spatial distribution pattern was aggregation distribution ,and the basic component was individual group ,with individuals attracting each other .Aggregation averages of twelve ju-jube orchards were more than 2 ,which indicated that aggregation distribution was connected with the combined effects of pathogen own aggregation behavior and environmental factors .Using Iwao’s statistical methods ,models to determine the optimal theoretical sampling number and the optimal sequential sampling number were presented .关键词
