摘要
对关中地区主要城市绿地和公园的草坪草锈病的病情指数及发病率的进行了调查,结果表明:陕西关中地区草地早熟禾的感病较为严重,匍茎翦股颖具有较强的抗病性。常见草坪草的抗病性排序为:匍茎翦股颖>高羊茅>多年生黑麦草>草地早熟禾。草坪草锈病发病高峰期为9月中旬;同一品种,随地理位置由东向西推移,病情逐步加重。室内抗病性接种测定结果与室外调查结果基本相符。
The disease index and incidence of turf-grass rust at urban green space and public park in central Shaanxi plain were investigated. The results showed that Poa pratensis had occurred severely in the survey area. Agrostis stolonifera exhibited comparably strong anti-disease ability. The disease resistance sequence of common four species of turf-grass were as follows： Agrostis stolonifera 〉Festuca arundinacean 〉Loliurn perenne 〉 Poa pratensis. The break out of turf-grass rust intensely occurred in the middle of September; For the same species, accompanying geographically moved from east to west, the infection of the disease gradually became intensified. Indoor resistance inoculation test results showed the same trend.
