| 摘 要： | 水稻纹枯病属于中心式传播型，病菌的菌核及病害在田间水平分布不均匀，稻田中央菌核量最少，发病程度较轻；稻田下风池角和池边菌核量较多，发病程度较重，深水串灌未晒田和排水不良的深水地块发病严重。偏施氮肥地域发病较重。

| Abstract: | Rice sheath blight were central disseminate pattern diseases in field.The horizontal distribution of the fungus sclerotia and diseases were not proportional in field. The fungus sclerotia quantity and incidence of a diseaseswere minimum in middle of field, and it was maximum in borderland. The incidenceof a disease was maximum in water depths and a good many of nitrogenous fertilizer. |
