1988～1992年对我国橡胶垦区橡胶褐皮病的发生规律调查结果表明:纬度越低,发病越重,高温多湿是褐皮病发生的重要条件;不同品系对褐皮病有不同抗病力,PR107、GT1病情较轻,具有一定抗病力,RRIM600、PB86则较感病;同一品系,树龄越大,发病越重;采胶强度如割胶次数、深度、使用刺激剂等直接影响胶树抗病力,与发病有密切关系。从林段病株的非随机分布及病树对抗菌素的明显反应看出,橡胶树褐皮病是一种传染性病害。
From 1988 to 1992, the investigation on the rule of occurrence of rubber brown leather disease in rubber reclamation areas in China showed that the lower the latitude, the heavier the disease incidence and the more the high temperature and more humidity are the important conditions for the occurrence of brown leather disease. Different strains have different resistance to brown leather disease, PR107, GT1 had mild disease and had certain resistance to disease, while RRIM600 and PB86 were more susceptible; the same strain, the older the age, the heavier the incidence; the plasticizing strength such as the number of tapping, the depth, the use of stimulant, Disease, and the incidence is closely related. From the non-stochastic distribution of diseased plants in the forest and the apparent reaction of the diseased trees to the antibiotics, it is seen that the diseased rubber tree is a contagious disease.
