烤烟托盘水床育苗大田示范效应研究

对烤烟托盘水床育苗和常规(营养袋)育苗的烟苗素质及其大田生长发育情况和产量、质量进行了对比分析,结果表明:托盘水床育苗烟苗素质优于常规育苗;托盘水床苗移栽大田后生长迅速,植物学性状优于常规苗,并对烟株上部叶开秸开片作用明显,收获叶片平均增加2片左右;托盘水床苗抗花叶病效果明显,且大田生育期延长,对叶片干物质的形成和积累有利;其产量、产值、均价和上等烟比例等各项指标均优于常规苗,特别是产值和上等烟比例提高幅度较大,分别达到25.52%和24.15%。

Study on Paradigm Effect of Seedling Production with Plastic Trays and Seedbed with Water in the Flue-cured Tobacco Field

the quality, growth and development conditions of flue-cured tobacco seedlings prepared by plastic trays and seedbed with water or by conventional measures were analyzed, and the yield and quality of tobacco was compared. The result showed that quality of seedlings prepared by plastic trays and seedbed with water is better than that of conventional measures. After transplantation to the fields, the former seedlings grow faster, and the former botanical characters were better than that of the conventional seedlings. Measure had apparent effect on upper leaves, with about 2 additional leaves in yield. The seedlings of plastic trays and seedbed with water were obviously resistant to mosaic disease and field growth period were prolonged, so it was good for dry material formation and accumulation of leaves. Other indexes like yield, production value, price and promotion of high-rate tobacco leaves were all higher than that of conventional seedlings. The increase of production value and high-rate tobacco leaves were most drastic, and increased 25.52% and 24.15% respectively.
