| 摘 要： | 通过２８块典型样地调查，经数据处理后得出：林中红松疱锈病的发生程度与病原中转寄主马先蒿属植物存在与否关系密切。两者相距５０ｍ以上时，病害明显减轻。不同罹病程度林分的土壤物理性状调查表明：土壤渗透系数越低，林分患病与马先蒿出现的频率越高。立地土壤中主要营养物质含量的高低与病害的发生程度关系不显著。 |
| 关 键 词： | 红松疱锈病 马先蒿 病原中转寄主 |

| Abstract: | The investigation of main factors of the stands from 28 sample plots, analyzed with different mathematical methods, showed that the disease caused by Cronartium ribicola had a close correlation with its intermediate host Pedicularis spp. existing. The disease decreased distinctly while the host beyond 50m. The analysis of the soil physical properties showed that the severity of the disease and the frequency of Pedicularis spp. occuring had the tendency of increasing with the decrease of soil osmotic coefficient. The relationship between the main nutrition content of the soil and the disease severity is not remarkable. |
