摘　　要：在陕北黄土丘陵沟壑区,通过20年的调查与监测,认为大金星和敞口2个山楂品种可作为该区的主栽品种。山楂在该区海拔1250m以下的地块生长结果良好;东坡和西坡的树体生长量、产量等高于南坡和北坡。水平梯田和鱼鳞坑较隔坡梯田和水平阶利于山楂生长结果:主干疏层形比其它树形的树体生长量大,产量高。After 20 years investigation and observation in Loess Hilly and Gully Region in Northern Shaanxi, Dajingxing and Changkou of hawthorn varieties are recommended to be dominant varieties in this region. Below an altitude of 1250 meters, hawthorn grows and fruits better than over an altitude of 1250 meters. In eastern and western slope land, hawthorn growth mass and yield are more than in southern and northern slope land. Level terrace and fish scale pit are more beneficial to hawthorn grow than slope-terrace and level step so hawthorn has more yield. The tree＇s form of central leader type training has more growth mass and more yield than other type training.
