油茶炭疽病是油茶生产上的一个严重问题,亟待解决。几年来,四川省林科所进行了从实验性到生产性的油茶炭疽病防治工作。1965年建立了防治样板,在252亩面积上综合防治的结果,病株率控制在4.82—9.62%之内,鞍周围651亩未防治的油茶林,保果增产了34.4%。现将油茶(成林)炭疽病的综合防治技术介绍如下:修除病部在12—2月(不超过3月上旬),对油茶树上病菌越冬组织和器官,如病(枯)枝、溃疡枝、病芽(痕)和枯蕾等进行修除。并尽可能清除病果和病叶。修除病枝以切至活部位的3—5厘米处为适度。大枝及干溃疡斑需刮至无变色的木质部为止。然后用药剂泥浆(西力生或硫酸铜泥浆)涂敷伤口。
Camellia anthrax is a serious problem in the production of Camellia, which needs to be solved urgently. Over the past few years, Sichuan Forestry Branch carried out from experimental to productive Camellia anthrax prevention and control work. In 1965, a model was set up for prevention and control. On the basis of comprehensive prevention and control of 252 mu of land, the diseased plant rate was controlled within 4.82-9.62%. 651 mu of non-controlled Camellia oleifera forest around the saddle increased the yield by 34.4%. Now Camellia oleifera (forest) anthracnose comprehensive prevention and control technology introduced as follows: repair of diseased parts in 12-February (no more than early March), the oil-tea tree overwintering tissues and organs, such as disease (dry) branches, Ulcer branches, buds (marks) and withered buds and other repair. And as far as possible remove disease and diseased leaves. Repair diseased branches cut to 3-5 cm at the living site is moderate. Large branches and dry ulcer spots need to be scraped to discolored xylem so far. The wounds are then coated with medicated mud (Silica or copper sulfate mud).
