摘　　要：采用不同质量浓度硫酸锌乳胶漆制剂处理容器内壁,研究对银荆(Acacia dealbata Link)播种苗生长的影响,结果表明,不同浓度硫酸锌乳胶漆制剂能显著抑制银荆容器播种苗主根长度的增加,无硫酸锌(对照)处理最长(11.90 cm),硫酸锌350 g/L处理最短(1.80 cm);然而,不同浓度硫酸锌乳胶漆制剂对容器播种苗的侧根数量、复叶数量、小叶数量、叶面积、茎重、根重及苗高的增加均具有显著的促进作用。综合分析结果认为,硫酸锌乳胶漆制剂250 g/L处理能显著抑制银荆容器播种苗主根的生长,可提高苗木的质量。The effects of different Zinc Sulfate （ZnSO4） concentrations on container seedlings growth of Acacia dealbata Link were investigated. The results showed that different ZnSO4 concentrations suppressed the root growth of A. dealbata, the 350 g/L preparations had the effect on root length, which was 1.80 cm, while the main root length of the control was 11.9 cm. However, various concentration of ZnSO4 preparations improved lateral roots number significantly, compound leaves number, leaflets number, leaf area, stem weight, leaf weight and seedlings height. 250 g/L of ZnSO4 preparations obviously suppressed the main root growth of A. dealbata and improved the quality of seedlings.
