| 摘 要： | 通过对白菜黑斑病的空间分布型进行研究,结果表明:在发病初期,白菜黑斑病空间分布型为随机分布;在病害发生1代以后白菜黑斑病多为聚集分布;在病害发生后期,单株病斑数大于1 000的地块,白菜黑斑病可能成为均匀分布.通过室内杀菌剂的筛选,结果表明:退菌特对白菜黑斑病菌的毒力最强,福美双、代森锰锌(新万生)对白菜黑斑病菌的毒力也很强,杀毒矾、速克灵、百菌清对白菜黑斑病菌也有较好的毒力. |

| Abstract: | The primary study on spatial distribution of Alternaria brassicae was made.The results showed spatial distribution pattern of Alternaria brassicae was a random pattern in the beginning of the disease developing.The distribution model was aggregation after a generation of the disease developing.To those fields that a plant had more than 1 000 lesions,the distribution model was mostly an even pattern in the last stage.Laboratory experimental result suggested that Tuzet was most effective to restrict Alternaria brassicae.Several other effective pesticides were chosen out such as Thiram,Mancozeb,Sandofan-M8,Sumilex,Daconil. |
