不同施氮量和留叶数对烤烟新品系S2-15生长、质量和效益的影响
Effects of Nitrogen Application Level and Remained Leaf Number on Growth, Quality and Economic Benefits of New Flue-Cured Tobacco Strain S2-15
摘要:
为在生产中更好地推广种植烤烟新品系S2-15,本试验通过不同施氮量、不同留叶数对新品系S2-15生长、质量和效益影响的研究。结果表明:以施纯氮量8.5 kg/666.7m2、留叶20片处理的大田抗病性较好,产量、产值和中上等烟比例等效益性状较好,原烟外观质量和烟叶的化学成分等品质特征表现较优。
Abstract:
Effects of nitrogen application level and remained leaf number on growth, quality and economic benefits of new flue-cured tobacco strain S2-15 were studied in order to promote the planting in production. The results showed that the disease resistance was good in tobacco field, economic characters of yield, output value and proportion of mid-high grade leaves were better, the appearance quality and chemical composition were better in the treatment of 8.5 kg/666.7m2 nitrogen application level and 20 leaves remained.
