| 中文摘要: |
| 通过大田试验研究了保水剂对烤烟生长及对其品质的影响，结果表明，保水剂的施用在烟草生长前期抑制了烟草的生长，但随生长期的延长，抑制作用有所缓解；低剂量保水剂（15 kg/hm2）的施用提高了烟叶中还原糖、钾的含量，并能显著地降低淀粉、烟碱和氯离子的含量，有利于烟叶品质的改善。保水剂的施用量为15 kg/hm2和30 kg/hm2时能明显提高烟叶的经济性状，增加烤烟生产的经济效益。 |
| 英文摘要: |
| This paper studied the effect of water-retaining agents on flue-cured tobacco growth and the tobacco qualities by field trail. The result indicated that the application of the water-retaining agents restrained the tobacco grow during the prophase grow, but the restrain could alleviate with tobacco growing. Appling low content of water-retaining agents (15 kg/hm2) increased significantly the content of reducing sugar and K, while reduced greatly the content of starch, nicotine and chlorine, so improved the quality of tobacco. And the application of content of 15 kg/hm2 and 30 kg/hm2 treatment could improve significantly the yield, value, percentage of superior leaves, and so increased the economic benefit. |
