摘要
研究了不同质量分数CuSO4乳胶漆制剂处理容器内壁对银荆播种苗生长的影响。结果表明:不同浓度CuSO4乳胶漆制剂对银荆播种苗主根生长具有抑制作用,浓度为270g/LCuSO4处理后的银荆播种苗主根最短(1.125cm),对照组最长(9.5cm);不同浓度CuSO4乳胶漆制剂对容器苗侧根数量、复叶数量、小叶数量、叶面积、茎重、根重及苗高增加均具有显著的促进作用;190g/L CuSO4乳胶漆制剂处理容器内壁能显著抑制银荆1a生播种苗主根生长,提高苗木质量。
The effects on container seedlings growth of Acacia dealbata Link by using different concentrations copper sulfate emulsion paint preparations to treat the inner wall of container were studied. The results showed that different concentrations copper sulfate emulsion paint preparations suppressed container seedlings of Acacia dealbata Link to increase its main root length,the concentration of 270 g/L had the best effect on the root length,which was 1. 125 cm, while the main root length of the control was 9. 5 cm. However, various concentration copper sulfate emulsion paint preparations improved significantly lateral roots number, compound leaves number, leaflets number, leaf area, stem weight, leaf weight and seedlings height. In conclusion, the copper sulfate emulsion paint preparations concentration of 190 g/L suppressed obviously the main root growth of annual container seedlings of Acacia dealbata Link and improved the quality of seedlings.
