橡胶树割面死皮具有经济重要性,因它会使胶树不产胶。死皮树比相邻的树长得快,而且争光、争肥。死皮树在老胶园是常见的,而在高产品系的开割幼树区和实行强割制度的植区也日益流行。小胶园的割胶频率太高或采用双线割胶,因而引起死皮。此外,小胶园抚管差,施肥不定期,又不根据胶树的养分需要施肥等也是导致死皮发生率高的因素。 Rubber tree cut surface dead skin is of economic importance, because it will not gum plastic production. Dead skin trees grow faster than adjacent trees, and win glory, fight fat. Dead skin trees are common in old rubber plantations, and growing areas in high-yielding saplings and areas under strong cuttings have also become increasingly prevalent. Small rubber plant tapping frequency is too high or double tapping, which led to dead skin. In addition, small rubber garden poor management, fertilization from time to time, but not according to the nutrient needs of the gum tree fertilization, etc. are also factors that lead to a high incidence of dead skin.
