摘要
通过田间试验，分析研究不同水氮配合对烟叶产质量的影响。试验结果表明：氮肥和水分对烟草生长发育及其产质量影响较大。在盘县生态条件下，根据当地土壤肥力、气候条件、烤烟品种以及种植制度等生态条件进行全面考虑分析，当氮肥施用量为90kg／hm^2时。在烤烟生长旺长期内进行人工补水至70％-80％，可有效提高烤烟生产上烟叶的产质量。
Through the field test, the influence of different coordination with water -nitrogenous fertilizer to output and quantity of tobacco leaves was analyzed. The result indicated that nitrogenous fertilizer and water had greatly influence to the growth,output and quality of tobacco. In the ecological condition of Panxian,considered comprehensively about soil fertility,climatic conditions,tobacco variety and cropping system,when nitrogenous fertilizer employment quantity were 90 kg/hm^2, and supplied 70%-80% water to tobacco in prosperous long-term,the output and value of lobaeco could be enhanced effectively.
