橡胶死皮病是指橡胶树割线局部或全部不排胶,严重时树皮产生褐色斑点、斑纹,树皮爆裂和割面形变的症状。由于典型的死皮病常有褐色斑点和斑纹的出现,因而称之为“褐皮病”(Brown Bast),但死皮病的病皮并不一定都产生褐斑,因而也有人称之为干皮(Dry Bark),我国则惯称为死皮或死皮病。本文中所讨论的不包括“吊颈皮”,“水冲胶”等引起起的死皮病。一、死皮病的成因自Gallagher(1909)开始记载死皮病以来,已有70余年的研究历史。研究历程中有一些人认为死皮病系病理性病害,如Keuchenius(1924)认为褐皮病是由乳管中的细菌引起的,Taysum(1960,1964)认为此病可能是由某种病原细菌侵染所致,
Rubber dead skin disease refers to the rubber tree cut off some or all of the plastic, serious bark produce brown spots, markings, bark rupture and cutting deformation symptoms. Because typical dead skin disease often has the appearance of brown spots and stripes, it is called “Brown Bast,” but the skin of an imminent skin disease does not always have brown spots and is also called dry Dry Bark, our country is used to call dead skin or dead skin disease. Discussed in this article does not include “hanging neck”, “Shuijiao” caused by dead skin disease. First, the causes of dead skin disease Since Gallagher (1909) began to write dead skin disease, has more than 70 years of research history. Some people in the research course think that dead skin disease is a pathological disease, such as Keuchenius (1924) that the brown skin disease is caused by the bacteria in the milk tube. Taysum (1960, 1964) thinks the disease may be caused by certain pathogenic bacteria Infection caused,
