| Abstract: | The article analysised the influence of environmental facters from three aspects： the employ amounts of nitrogen feitilizer,the disease power of rice sheath blight from different regions,the morbidity of rice sheath blight of rice varieties from same region.The results telled us three contents： the relation of employ amounts of nitrogen feitilizer and extend of rice sheath blight,the discrepancy of the disease power of rice sheath blight from diffenent regions、the discrepancy of the morbidity of rice sheath blight of rice varieties from same region.The results offered information for resolve the production questions. |
