沙培和化控在烤烟轻简高效育苗中的应用研究

摘要

In order to explore simple and efficient technology in the floating seedling segment,tobacco seedlings were trea-ted with sand cultivation and chemical control.Effect of different treatment was investigated on the quality,physiological ac-tivity of seedlings and reducing employment.The results show that free cutting leaves could be realized by sand cultivation and chemical control in exercising seedlings stage.The purpose of raising seedlings easy and simply was realized because of saving 3.4 days labor per hectare.Quality and physiological activity of seedlings which treated with sand cultivation and chemical control were significantly improved than contrast,so the purpose of high quality and efficiency was realized in rai-sing seedlings stage.%为探索烤烟漂浮育苗环节的轻简高效技术，采取沙培、化控组合处理烟苗，考察各处理对成苗期烟苗素质、生理活性和降低用工方面的效果。结果表明，沙培加化控育苗能够实现免剪叶炼苗，每公顷节省3.4个用工，实现了轻简育苗目的；沙培加化控处理的烟苗素质、生理活性比对照明显提高，实现了优质高效育苗目的。
