摘要

采取田间小区试验,研究了不同保水剂施用量对烤烟大田生长及烟叶产质量的影响.结果表明,适度剂量的保水剂能促进烟株生长,提高烟叶产量、上等烟的比例及产值,综合表现以1g/株的用量较为适当.%Using plot experiment, the effect of different amount of soil water - holding agent on the growth of flue - cured tobacco and the tobacco field quality were studied. The results showed that moderate amount of water retaining agent can promote the growth of tobacco, enhance leaf area, and thus increase tobacco production and the rate of high class leaf.
