讨论橡胶树早高产综合栽培措施和效果．早高产综合措施包括：①橡胶树采用刺激割胶适宜开割树围为49～52cm；②使用高效复方乙烯利乳剂刺激，并实行低频割胶；③应用深沟盖草培肥；④实行配方平衡施肥，年施橡胶高产专用复合肥1.2～1.5kg／株．四项措施的综合应用，使开发试验区的橡胶树初产期（5a）减刀53％、增产25．3％、提高割胶劳动生产率130％、节省割胶成本1／3、减少死皮发病指数1／3，从而获得“高产、高效、低耗、安全”的效果．橡胶树早高产技术累计推广应用面积3428．5hm2，平均增产10．9％，累计增产干胶418．7t．大面积的应用效果表明此措施是可行的．
Discuss the rubber tree early high yield comprehensive cultivation measures and results. Comprehensive measures for early high yield include: ① rubber tree used to stimulate the tapping appropriate cutting tree circumference is 49 ~ 52cm; ② the use of high-performance compound ethephon emulsion stimulation, and the implementation of low-frequency tapping; ③ application of deep ditch cover grass and fertilizer; ④ formula balanced fertilization, Years of high-yield rubber compound fertilizer 1.2 ~ 1.5kg / strain. The comprehensive application of the four measures will reduce the initial rate of rubber tree development (53%), increase the yield by 25.3%, increase the labor productivity of tapping by 130%, save the tapping cost by 1/3, and reduce the index of the incidence of dead skin / 3, to obtain “high yield, high efficiency, low consumption, safety” effect. Rubber tree early high-yielding technology has a total area of 3428.5hm2 popularization and application, with an average yield of 10.9%, an increase of dry adhesive 418.7t. Large-scale application shows that this measure is feasible.
