施氮量与种植密度互作对烤烟生长发育的影响OACSTPCD
Effects of Interaction between Nitrogen Application Rate and Planting Density on Growth and Development of Flue-cured Tobacco
研究了不同施氮量与种植密度对云烟87品种大田生育期、农艺性状和经济性状的影响.试验结果表明,在一定范围内,随着施氮量的增加,种植密度的相对减少更有利于烟株个体的发育尤其是大田后期生长,农艺性状表现更优更稳定.从施氮量水平看,施氮量在112.5 kg/hm2时整体表现最稳定,特别是经济性状总体表现最优；从种植密度上看,行株距在110cm×50 cm有利于烟株大田生长,提高了烟叶的经济性状,同时兼顾了产量和质量.
The effects of the interaction between nitrogen application rate and planting density on the growth period, agronomic characters and economic traits of flue - cured tobacco variety Yunyan 87 were studied. The results showed that when nitrogen fertilizer application rate was increased in proper range, the relatively low planting density was more propitious to the development of tobacco plants especially at later growth stage, and their agronomic characters we…查看全部>>
