摘　　要：以山西吕梁地区核桃品种“晋龙2号”为研究对象,对试材进行不同浓度的MgS O4处理,研究表明,0.1%∽0.2%MgS O4促进“晋龙2号”的干周,增加了株高,并促进枝梢生长,同时能够提高“晋龙2号”核桃树单株产量,提高单果重,可以作为推荐浓度进行喷施。而高浓度的硫酸镁（0.6.%）对“晋龙2号”生长不利,降低了核桃品质。This paper based on the walnut variety ＂Jinlong No.2＂as the research object, did processing with different con- centrations of MgSO4 on the test material, the result showed that 0.1%-4）.2% MgSO4 promoted the trunk girth of＂Jinlong No.2＂, increased the plant height and promoted the growth of the topmost, at the same time, improved the yield of per plant trees, increased the weight of fruit, could be used as a recommended concentration for spraying. But a high concen- tration of magnesium sulfate （0.6. %） had a bad influence on the growth of ＂Jlnlong No.2＂, reduced the quality of walnut.
