东平县北部山区面积占全县总面积的1/3,属青石山地。山区群众历来就有栽培核桃的习惯,但核桃园低产低效的问题较为普遍。为此,我们于2000—2007年进行了‘元丰’核桃优质丰产栽培试验,并进行了大面积推广,到目前,全县以‘元丰’为主栽品种的良种核桃面积已达2960hm2,2001年被国家林业局命名为“中国核桃之乡”。
The northern mountainous area of Dongping County accounts for 1/3 of the total area of the county, which belongs to the Qingshi Mountain. Mountain people have always had the habit of cultivating walnuts, but the problem of low yield and low efficiency of walnut is more common. To this end, we carried out ’Yuanfeng’ walnut high yield cultivation experiment and carried out a large area popularization from 2000-2007. Up till now, the area of elite walnut with “Yuanfeng” as main planting variety has reached 2960hm2, In 2001 by the State Forestry Administration named “China walnut town ”.
