Abstract
Abstract Nitrogen (N) fertilizer recommendations for burley tobacco (Nicotiana tabacum) seldom are adjusted to compensate for available N supplied when cover crops and/or animal manures are part of the cropping system. A field study was initiated to assess i) N availability from cover crops and manures to burley tobacco, ii) response of burley tobacco to N fertilizer provided by cover crops or manures, and iii) the usefulness and adaptability of soil testing and/or plant analysis for evaluating the supplemental fertilizer N needs of burley tobacco. The experimental design was a split-plot with fallow, crimson clover (Trifolium incarnatum), hairy vetch (Vicia villosa), rye (Secale cereale), and rye + hairy vetch cover crops and fall-applied and spring-applied manure as main plot treatments and five fertilizer N rates ranging from 0 to 200 kg N ha−1 in 50 kg N ha−1 increments as split-plot treatments. Soil and tobacco petioles were sampled in the 0 kg N ha−1 check plots during the growing season to determin...
当覆盖作物和/或动物粪便作为种植系统的一部分时，白肋烟(Nicotiana tabacum)的氮肥推荐用量很少调整以补偿速效氮的供应。为评价覆盖作物和肥料对白肋烟氮素的有效性，白肋烟对覆盖作物和肥料提供的氮肥的响应，以及土壤试验和/或植物分析对评价白肋烟氮素补充需求的有效性和适应性，开展了田间研究。试验设计以休耕、红三叶草(Trifolium incarnatum)、毛叶紫薇(Vicia villosa)、黑麦(seale cereale)和黑麦+毛叶紫薇为覆盖作物，以秋施和春施有机肥为主要小区处理，5种氮肥施氮量为0 ~ 200 kg N ha - 1，以50 kg N ha - 1为增量，分小区处理。在0 kg N ha−1对照区，在生长季节取样土壤和烟草叶柄，以确定
期刊介绍：
Chinese Tobacco Science is an academic scientific journal (bimonthly) under the supervision of the Ministry of Agriculture and Rural Affairs of the People's Republic of China, and sponsored by the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences and the Qingzhou Tobacco Research Institute of China National Tobacco Corporation. It was founded in 1979 and is publicly distributed nationwide. The journal mainly publishes academic papers on scientific research results, new production technologies, and modern management in my country's tobacco science research and tobacco production technology. In addition, it also publishes forward-looking review articles in the field of tobacco research. There are columns such as tobacco genetics and breeding, cultivation technology, modulation and processing, physiology and biochemistry, plant protection, review or monograph, quality chemistry, etc.
