化肥配施炭醋材料对烟草生长和产量与品质的影响

以烟草K 326为试验材料,通过一年两点试验研究了化肥配施炭醋材料对烟草生长的影响。结果表明,在常规化肥基础上减量施肥,不利于烟草生长,产量、品质有下降趋势。在相同化肥施用量基础上配施炭醋材料,提升了烟叶的农艺性状、经济性状和品质。减量化肥配施炭醋材料较常规施肥烟叶的产量、产值、上等烟比率分别提高了7.28%~26.29%,15.11%~49.61%,5.90%~42.70%。化肥减量20%配施炭醋材料较常规施肥已有增产提质的效果。

Effect of chemical fertiizer mixing with biochar and pyroligneous on growth,yield and quality of tobacco

The effect of mixture of biochar and pyroligneous in combination with different concentrations of a chemical fertilizer on the growth was investigated using the Tobacco K326 during a year in two different plot experiments.The results revealed that reducing conventional fertilizer application was bad for growth,yield and quality of tobacco and showed downward trend.But mixture of biochar and pyroligneous coordinating with reduced chemical fertilizer which was one-off application could promote agronomic traits,economic properties and chemical component quality to different extent,with the highest increase of yield,value and ratio of high grade leaves of 26.29％,49.61％,and 42.70％ respectively.Compared with conventional fertilization,as the fertilizer application was reduced by 20％ mixing with mixture of biochar and pyroligneous,the yield and quality both increased.Effect of general fertilization and reducing it by 10％ mixing with mixture of biochar and pyroligneous were the best.Taken together,our results support the theory of "less fertilizer,but positive effects" for both yield and quality.
