摘要:

以‘云烟87’为供试品种,采用大田试验方法研究低肥力土壤不同施氮量及配施有机肥对烤烟生长发育及产质量的影响。结果表明,在一定范围内施氮量的增加促进了烟株的生长发育,有利于烤烟产量和质量的形成,但是纯氮量增加到126 kg/hm2时病害加重,烤烟质量有降低趋势,增施腐熟农家肥处理农艺性状、经济性状优于增施商品有机肥处理。从田间表现、农艺性状、抗逆性及经济指标综合分析T4处理(处理1的施肥量+腐熟农家肥16500 kg/hm2)表现最好,其次是T5处理(处理1的施肥量+商品有机肥1500 kg/hm2),T2处理(按当地常规肥量增加10%施用烟草专用复合肥,施氮量115.5 kg/hm2)次之,T3处理(按当地常规肥量增加20%施用烟草专用复合肥,施氮量126 kg/hm2)和T1处理(常规对照,施氮量105 kg/hm2)表现较差,T6处理(无肥对照)表现最差。

Abstract:

To study the effects of different nitrogen rates and organic fertilizers on the growth, yield and quality of flue-cured tobacco in low-fertility soil, the field experiment was conducted with ‘Yunyan 87’. The results showed that the growth and development of flue-cured tobacco plants were promoted with the increase of nitrogen application rate in a certain range, and the yield and quality of flue-cured tobacco were formed. However, the disease was aggravated and the quality of flue-cured tobacco tended to decrease when the amount of pure nitrogen increased to 126 kg/hm2. The agronomic and economic characters of the treatment of adding decomposed farm manure were better than that of adding commercial organic fertilizer. In summary, according to the comprehensive analysis of field performance, agronomic traits, stress resistance and economic indicators, T4 (treatment 1 fertilization + decomposed farm manure 16500 kg/hm2) treatment was the best, followed by T5 (treatment 1 fertilization + commercial organic fertilizer 1500 kg/hm2) treatment, and T2 (increasing 10% of local conventional fertilizer, applying 115.5 kg/hm2 of nitrogen) treatment, T3 (increasing 20% of local conventional fertilizer, applying 126 kg/hm2 of nitrogen) and T1 (conventional control, applying 105 kg/hm2 of nitrogen) treatments were worse, and T6 (no fertilizer control) treatment was the worst.
