【摘要】 通过对乌盟呼市地区部分林场、苗圃、果园的考察,考证核对了本地区以辽宁山楂为主体的山楂属植物的三个种:辽宁山楂(C.sanguinea pall.)毛山楂(C、max imowiczii Schenid),光叶山楂(C.dahurica koehwe)。发现本地区山楂属第四个种——山检(C.pinnatifida Bge),山里红。发现马盟引进了一种有希望的砧木资源——甘肃山楂(C.kansuensis uils)。毛山楂嫁接大山楂表现矮化,丰产。几年来本地区山楂引种、育苗、建园积累了一定的经验,也存在不少问题。今后应注意利用当地资源,发展优良品种。适地适栽,加强管理,加强各部门的横向联合,将乌盟及呼市地区山楂产业经济迅速发展起来。更多还原
