一、概说油桐用处多,特别是桐油与人们日常生活有着密切的关系,长期以来一直成为我县重要经济树种之一.据调查农民植桐已有一百多年历史,迄今仍保持着少量50年生左右的老桐树.解放后,在党和人民政府的重视和支持下,开始营造成片油桐林,油桐生产得到了很大发展.但由于十年文化大革命的影响及油桐经济政策的波动,产量、经济效益较低等原因,致使桐林生产几经挫折.我县解放初期至1981年累计营造桐林86553亩,现实有8000亩左右,保存率仅为9.2%.其中1951—1962年计造林18730亩,但实际只有1346亩,保存率为7.2%;1963—1970年造林加原保存数共55609亩,1974年林业资源调查为1914亩,保存率为3.4%;1978—1981年共造林13560亩,1983年春调查是6100亩,保存率为50%.桐油产量1971年最高为14.8
