由于割胶技术差,会造成割面伤害.割胶时,当一部分形成层被割掉而曝露出木质部时,就使再生割面长木瘤和凹凸不平,使得下次割胶产生困难.另外,当伤害的因素是寄生真菌而不是胶刀时,由于真菌能严重损害割面,引起的效果更坏.如果环境条件适宜于它们生长时,就从一个侵染点开始生长并破坏大面积的再生皮.主要的致病真菌是橡胶割面霉腐病病原菌.(Ceratocyctis fim—briata)它引起割面霉烂,而疫霉菌(Phyto-phthora)引起条溃疡.比较次要的是腐皮镰孢菌(Fusariumsolani)和褐腐病菌(Botry-odiplodia theobromae),褐腐病菌病是最近记录的割面坏死的偶然因子.
As tapping technology is poor, it will cause cut damage.When tapping, when a part of the formation layer is cut off to expose the xylem, the regenerated cut surface long wood tumor and uneven, making the next tapping difficult.In addition, when the injury The factor is parasitic fungi rather than plastic cleaners, which cause even worse effects because the fungus can severely damage the cut surface and, if the environmental conditions are suitable for their growth, begin to grow from one infestation point and destroy large areas of regenerated skin. The major causative fungus is the pathogen of rubber cut mildew (Ceratocystis fim-briata), which causes mildew on cut surfaces, while Phyto-phthora causes ulceration of the strips, and more importantly Fusarium solani ) And Botry-odiplodia theobromae, Brown rot pathogen is the accidental factor recently reported for cut necrosis.
