营养土与促根营养液配施对初烤烟产质量的影响

Effects of Added Nutrient Soil Combined with Root-promoting Nutrient Solutionon Yield and Quality of Flue-cured Tobacco

为了探索营养土、促根营养液在烤烟生产中的应用效果,以草炭、菇渣、锯木屑等为原料配制营养土,以黄腐酸钾、氨基酸、复硝酚钠等为原料配置营养液,通过田间小区试验,在烟苗移栽时,设置3个处理,分别为促根营养液、营养土和促根营养液+营养土,以常规栽培为对照,研究不同处理对初烤烟物理特性、化学成分、经济性状及感官质量的影响。结果表明,与对照相比,3个处理烟叶叶长、叶宽、开片率等物理性状均显著增加,烟碱和氯含量降低,产量和质量提高,其中营养土和营养液配施时效果最好,其初烤烟上等烟比例、均价、产量和产值分别较对照显著提高12.15百分点,17.54%,8.48%,27.51%。综合说明,移栽时营养土和营养液配施能较好的改善初烤烟物理特性、协调化学成分、提高经济性状、提升感官质量。

In order to explore the effects of nutrient soil and nutrient solution onflue-cured tobacco production,the experiment was conducted with field plot trial,three treatments including root promoting nutrient solution,nutrient soil and root promoting nutrient solution+nutrient soil were set in the transplanting of tobacco seedlings,the conventional cultivation was as the control,the effects of different treatments on the physical properties,chemical composition,economic characters and sensory quality of primary flue-cured tobacco were studied.The nutrient soil was prepared with peat,mushroom residue and sawdust,and the nutrient solution was prepared with potassium fulvic acid,amino acid and compound sodium nitrophenolate.The results showed that compared with the control,the physical properties such as leaf length,leaf width and leaf opening rate of the three treatments increased significantly,the contents of nicotine and chlorine decreased,and the yield and quality indices were enhanced.Among the three treatments,the root promoting nutrient solution+nutrient soil treatment had the best effects,which the ratio of high grade tobacco leaves,average price,yield and output value of the flue-cured tobacco significantly increased by 12.15 percentage points,17.54%,8.48%,and 27.51%compared with the control.Comprehensively,the nutrient soils combined with the root-promoting nutrient solution could improve the physical properties,chemical composition,economic properties,and sensory quality of primary flue-cured tobacco.
