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:施入水杨酸处理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(100-300kg/h)的增加而持续增加。水杨酸300kg/h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138kg/h,产值提高1000元/h以上,中上等烟比例显著提高了15%以上。
In order to study the salicylic acid fertilizer synergist on the flue-cured tobacco dry matter and quality of production, different concentrations of salicylic acid treatment plot test. The results showed that applying salicylic acid could all promote the increase of dry matter and yield and quality of flue-cured tobacco to some extent. With the increase of salicylic acid concentration (100-300kg / h) Increase and continue to increase. Salicylic acid 300kg / h can coordinate the chemical composition of tobacco, increase the contents of nicotine, total nitrogen and chloride, increase the contents of nicotine, total nitrogen and chloride, and make the ratio of nitrogen to alkali, , To meet the internal coordination of the chemical constituents of flue-cured tobacco to the maximum extent. Compared with conventional fertilization, the yield increased by 138kg / h, the output value increased by more than 1000yuan / h, and the proportion of middle-high grade tobacco increased significantly by 15% or more.
