橡胶生产的发展与其它作物一样,是广大劳动人民和科学家在生产实践、科学研究中不断选育新品种和推广良种,使产量成倍增长的结果。自一八七六年魏克汉从巴西将野生橡胶引入东南亚大面积种植以来,至今只有一百多年历史,产量就翻了几番,由原来亩产30公斤提高到80—120公斤。马来亚橡胶研究所一九七七—一 The development of rubber production, like other crops, is the result of a doubled production of the vast majority of working people and scientists in breeding and promoting new varieties in production practices and scientific research. Since 1876, when Weikhan introduced wild rubber from Brazil into large-scale planting in Southeast Asia, it has only a hundred years of history and its output has doubled from 30 kilograms per mu to 80-120 kilograms.
