我县龙岗公社龙江大队素有“油桐之乡”的称号,1963年达到了每户千株桐,被评为全国林业先进单位。近十年来,这个大队在毛主席“以粮为纲,全面发展”的方针指引下,油桐生产又有了新发展,与1963年相比新栽桐树两万多株,株数增加了22％,桐籽产量增长了58％,做到了连年稳产丰产。1973年在684亩粮桐间作的土地上,又获得了粮桐双丰收,共收粮食32万斤,桐籽10.5万斤,平均亩产粮食467斤,桐籽154斤。仅桐籽收入一项达24,150元,占全大队总收入的40％多,每户平均收入210元。他们夺得油桐稳产丰产的主要技术经验是: County Longgang commune Longjiang brigade known as “Tung town” title, 1963 reached a thousand strains Tong, was named the national forestry advanced unit. In the past decade, under the guidance of Chairman Mao’s principle of “taking grain as the key link and all-round development,” the brigade has made new progress in the production of tung oil tree and has newly planted more than 20,000 tung trees and increased the number of trees by 22 times %, Tong seed production increased by 58%, so that in successive years steady yield and high yield. In 1973, 684 acres of grain on the inter-crop land, they won the double-harvest of grain Tong, received a total of 32 million pounds of grain, Tong seed 105,000 pounds, the average yield of 467 pounds of grain, Tong seed 154 pounds. Only Tong seed income of a reached 24,150 yuan, accounting for more than 40% of the total revenue of the brigade, the average income of 210 yuan per household. Their main technical experience of winning the steady and high yield of tung tree is:
