摘要
通过田间调查明确临猗梨枣(Ziziphus jujuba Mill.cv.Linyi Lizao)褐斑病的发病症状和发病情况,将红枣专用肥、复合肥料、钙硼锌肥、微量元素水溶肥和80%代森锰锌药剂分别组合成12组处理对山西省太谷区北张村进行临猗梨枣褐斑病防治试验。结果表明,临猗梨枣褐斑病在果实膨大期、着色期均有发病,发病部位一般在果实肩部,病斑凹陷,果皮皱缩,果肉软榻味苦,病斑边缘清晰。8月中旬梨枣褐斑病开始发病,9月下旬发病显著加重,发病率达43.4%,到10月初发病最严重,发病率高达59.1%。在防治试验中,红枣专用肥+钙硼锌肥+80%代森锰锌(T3)组合防治临猗梨枣褐斑病的效果最佳,防效达66.1%。
To investigate the symptoms and incidence of brown spot disease of Ziziphus jujuba Mill.cv.Linyi Lizao were investigated in the field,and the disease control tests were performed using jujube special fertilizers,compound fertilizers,calcium boron and zinc fertilizers,water-soluble trace element fertilizer and 80% mancozeb combined into 12 treatments in Beizhang Village,Taigu,Shanxi Province.The results showed the disease occurred in enlargement period and coloring period and the disease position was usually in the shoulder of the fruit,the lesion was depressed,the peel was shrinked,the flesh was soft and bitter,and the edge of the lesion was clear.The disease began to occur in mid-August.In late September,the incidence increased significantly(43.4%)and the incidence was the most serious in early October(59.1%).In the control experiments,the T3 treatment of jujube special fertilizers+boron and zine fertilizer+80% mancozeb had the best effect on the control of jujube brown spot disease,and the control effect was 66.1%.
