硫酸铜不同施用时间和不同施用量对烤烟漂浮育苗的影响
Effects of Different Application Time and Dosage of Cupric Sulfate on Floating Seedling of Flue-Cured Tobacco
摘要:
研究了烤烟漂浮育苗过程中，硫酸铜不同施用时间、不同施用量对烟苗生长发育的影响。结果表明，苗池施用硫酸铜对烟苗整齐度不产生影响，在一定范围内随着硫酸铜浓度的增加对烟苗的生长有促进作用，播种前施用17.28 ppm的硫酸铜可促进烟苗生长发育，而且硫酸铜施用时间越早对烟苗的生长越有促进作用，随着硫酸铜施用时间的推迟成苗期烟苗鲜重和干重明显减轻。
Abstract:
The effects of different application time and dosage of cupric sulfate on floating seedling of flue-cured tobacco were studied. The results showed that there was no effect of cupric sulfate on uniformity of tobacco seedling in seedling pond. It could promote the growth of tobacco seedlings with the increase of cupric sulfate concentration in a certain range. It could promote the growth and development of tobacco seedling by using 17.28 ppm copper sulfate before sowing. The earlier the application time of cupric sulfate, the better the growth and development of tobacco seedling. The fresh weight and dry weight of tobacco seedling decreased significantly with the delay of cupric sulfate application.
