摘要
2017年西双版纳植胶区橡胶树白粉病泛滥,据测算因白粉病导致天然橡胶产量损失12 283.8 t,金额达1.7185亿元。对橡胶树白粉病在不同橡胶种植农场、不同品系和植胶类型区的发病程度以及总体为害损失情况进行了实地调查。分析认为,山地胶园立体的小气候环境、关键物候期气象条件适宜是造成白粉病流行的客观原因,而现有管理体制下专业化监测防治队伍缺乏,导致了防治失利,加剧了病情危害。提出了新形势下橡胶树白粉病的防治建议。
In 2017, rubber powdery mildew outbroke in Xishuangbanna region and caused 12,283.8 t of natural rubber production loss, amounted to nearly 171,850 thousand yuan. Based on investigation of general loss and occurring charateristics of rubber powdery mildew in different rubber variaties with different plant rubber types in different farms,the outbreak reasons were analysed. Mountainous regions microclimate and suitable meteorological conditions in critical phenological period were major objective reasons for the disease epidemic.Weak power of professional monitoring and controlling in current management system aggravated damage of the disease. Therefore, controlling suggestions against rubber powdery mildew were put forward in the new circumstances.
