试验地点玉蟾林试站位于东径105°23′,北纬29°19′,海拔450米左右的丘陵山地,属亚热带气候类型。该站油桐枝枯日趋严重。1964年曾有零星发生,到1981年几乎全林感病,枯枝率达46％,致使部分植株衰枯,产量下降57.％。1981—1982年,对该病害的症状、病原菌、侵染循环、发生规律及防治方法等进行了初步试验。现将结果整理于后。
Test site Jadelin test station is located in the eastern diameter of 105 ° 23 ’, latitude 29 ° 19’, about 450 meters above sea level hilly mountains, is a subtropical climate type. The station tung tree branches increasingly serious. Some sporadic occurrence occurred in 1964. By 1981, almost all of the forest disease and the rate of dead branches reached 46%, causing some plants to decline and the yield to drop by 57.%. 1981-1982, the disease symptoms, pathogenic bacteria, infection cycle, the occurrence of the law and prevention methods were the initial test. Now the results sorted in.
