摘　　要：探索了华山松壮苗培育技术,对华山松容器苗喷施不同浓度BR-120生长调节剂及4种苗木类型育苗措施进行了研究,结果表明:喷施不同浓度BR-120生长调节剂对华山松70 d苗生长没有显著影响;芽苗切根、芽苗不切根、幼苗切根移栽、直播4种处理对苗高、地径、鲜重影响不明显,但对根系的生长有极显著影响。芽苗切根移栽根系发育较好,幼苗切根移栽次之,芽苗不切根和直播根系发育较差。We used different concentrations of a plant growth regulator,BR-120 on the seedlings of container planted Pinus armandi to test the growth promotion and fostering techniques.It showed that there was no significant effect on the seedlings of 70 days old after spraying different concentration of BR-120 tested on 4 types the seedlings.The treatments of cutting root of bud seedlings,no-cutting root of bud seedlings,transplanting after cutting root of seedling and direct planting of seedlings had no significant effects on the height,diameter at base and fresh weight of the seedlings,nevertheless,these treatments had significant effects on the roots＇ development.It showed that the treatment of cutting root of bud seedlings had well-developed rooting and then the cutting root of seedling the second,other 2 treatments had less developed rooting.
