我区16个县均有山楂资源分布。栽培面积达6万余亩,成龄树38万余株,1981年产量达894.7万斤,占全省总产量的90%。成龄山楂树大都分布在地头、埂边或山坡上,由于零星分散,立地条件差,加之缺乏精细管理,水土流失严重,致使山楂根系主体裸露,树势极度衰弱,产量低而不稳。为使山楂丰产,我们抓了以下措施。一、深翻改土,加厚活土层:山地果园的土壤管理主要是深翻,取石换土,里切外垫,修边垒埂,增厚活土层。零星树单株做一个小梯田;连片的搞成高埂方
16 counties in our district have hawthorn resource distribution. Cultivation area of more than 6 acres, more than 380,000 adult trees, production in 1981 reached 894.7 kg, accounting for 90% of the province’s total output. Most mature hawthorn trees are distributed on the ground, ridge or hillside. Due to sporadic scattered and poor site conditions, coupled with the lack of meticulous management, soil erosion is serious, leading to the bare body of root of hawthorn, extremely weak tree vigor, low and unstable yield. In order to make hawthorn abundant, we have caught the following measures. First, the deep changes in soil, thick soil layer: soil management of mountain orchards is mainly deep plowing, stone for soil, cut the outer cushion, repair edge barrier, thickened live soil. Sporadic trees to do a single small terraced fields;
