I stood in the spring of 1974 to help the commune Fubing Battalion to build a 60-acre grapevine yielding forest, of which 41 were a 1-acre trial plantation, with a higher degree of management integration. This mu forest produced 9.3 kilograms of oil in 1976, produced 5 kilograms of oil in 1977 and produced 33.96 kilograms of oil in 1978. The average yield per mu of 60 acres of high-yield forests is 9.35 kilograms. Now this Mu Tung Lin test conditions are described below: Site conditions, about 30 degrees slope, slope to the south, west. The soil is yellow in Devonian cyan shale
