通常认为褐皮病是一种由于过度割胶而引起的生理失调。虽然这种生理失调对胶树本身无害,但因此而造成的减产则关系到植胶者的利益。此外,褐皮病是确定割胶强度,由此间接决定产量的一个重要因素。 症状 生理失调初期阶段的特征是部分或全部割线不排胶。常常可以发现,由于死皮只限于一部分乳管列,所以,整条割线还在出胶。在死皮伴随出现褐色斑点的时 Beige disease is generally considered to be a physiological disorder caused by excessive tapping. Although this maladjustment is not harmful to the gum tree itself, the resulting reduction in production is in the interest of the weaver. In addition, the brown-skin disease is to determine the tapping strength, which indirectly determines the output of an important factor. Symptoms The initial stage of physiological imbalance is characterized by partial or complete secant line without glue. Often you can see that since the dead skin is only part of the milk tube column, the entire cut line is still out of plastic. When the dead skin accompanied by brown spots
