锈菌是引致森林病害的一类重要病原,所有锈菌目的锈菌都是专性寄生菌,与森林植物关系十分密切,由它所致的林木病害种类繁多,不少种类严重影响林木生长、种实产量与质量,甚至是难以防治的毁灭性病害.我省川西高山林区森林,过去一直处于原始状态,地处青藏高原的东南边缘,海拔高度在1600米—4500米间,峰峦起伏,地势参差,谷坡陡峻,相对高差一般为1000米—2000米,谷坡多在45°以上,林区气候受太平洋、印度洋和青藏高原三大气团的影响,年降雨量500—1100毫米,年平均气温6—15℃,最冷月平均气温-1-
Rust is one of the most important pathogens that cause forest diseases. All of the rusty fungi are obligate parasites and are closely related to forest plants. Due to the variety of forest diseases caused by it, many species seriously affect the growth of trees, The actual yield and quality, and even difficult to control the devastating disease .In our province, forests in the mountains and forests in the mountains, in the past has been in its original state, is located in the southeastern margin of the Qinghai-Tibet Plateau, the altitude of 1600 meters-4500 meters, ups and downs, The terrain is variable and the valley slope is steep. The relative elevation difference is generally 1000-2000 meters and the valley slope is more than 45 degrees. The forest climate is affected by the three air masses of the Pacific Ocean, Indian Ocean and Qinghai-Tibet Plateau. The annual rainfall is 500-1100 mm, The annual average temperature of 6-15 ℃, the coldest month average temperature of 1-
