摘 要:为了研究水杨酸肥料增效剂对烤烟干物质及产质量的影响,进行水杨酸不同浓度处理小区试验。结果表明:施入水杨酸均能在一定程度上促进烤烟干物质及产质量的提高,烤烟生长后期,烟株干物质积累量随着水杨酸处理浓度(100~300 kg/hm^2)的增加而持续增加。水杨酸300 kg/hm^2处理可协调烤烟化学成分指标,提高烟钾含量,降低烟碱、总氮和氯离子含量,使氮碱比、糖碱比和钾氯比等指标均在较为适宜的范围内,最大限度满足烤烟内在化学成分的内在协调性,且与常规施肥相比,产量提高137.5 kg/hm^2,产值提高1 168.2元/hm^2,中上等烟比例显著提高了近16个百分点。A plot test was conducted to analyze the effects of SA fertilizer synergist on dry matter,yield and quality of flue-cured tobacco. The results were as follows:to a certain extent, SA could promote the improvement of dry matter, yield and quality of flue-cured tobacco. In the later growth period, with the SA concentrations increased ( 100-300 kg per hectare), dry matter accumulation of tobacco plants increased. The treatment with 300 kg per hectare SA coordinated the chemical composition of flue-cured tobacco,made the content of tobacco potassium increased,while the content of nicotine, total nitrogen and chloride ion decreased ,made the ratios of nitrogen-nicotine,sugar-nicotine,potassium-chlorine and others in a relatively appropriate range, best satisfied the coordination of chemical composition, and compared with the treatment of common fertilizer, increased the yield by 137.5 kg per hectare, increased the output value 11 68.2 yuan per hectare, also significantly increased the first and second class tobacco ratio about 16points.
