橡胶树烂脚病亦称茎基寒害,是近年来我国植胶生产上出现的新问题.华南四省(区)均有发生,福建、云南、广西纬度较高的植胶区尤其严重.1976年在本所调查3980株成令胶树,其中烂脚4—6级树有1193株,占30%.烂脚4级以上的胶树,不但生长滞缓,产胶量下降,还因溃烂面积过大长期难以愈合,引起病、虫入侵,致木质腐烂,严重的整株死亡.为此,研究烂脚病的有效防治措施是植胶生产上的一项重要任务.
Rubber tree rotten foot disease, also known as stem-based cold damage, is a new problem in the production of plasticized plants in our country in recent years .Four provinces (autonomous regions) in South China occurred, especially in Fujian, Yunnan and Guangxi. 3980 strains in the investigation of the plastic tree, which rotten 4-6 trees have 1193 strains, accounting for 30%. Rotten feet more than 4 gum trees, not only the growth retardation, decreased production of plastic, but also because of ulceration Too long-term difficult to heal, causing disease, insect invasion, caused by wood rot, severe whole plant death.To this end, the study of effective prevention and treatment of rotten foot disease is an important task in the plastic plant production.
