摘要
以烟草品种“K 326”为研究对象,采用大田试验法,研究石灰添加量对烟草农艺性状、根茎病害情况、经济效益和烟叶品质的影响。结果表明,石灰添加量为20~40 kg·(667m^(2))^(-1)时,烟草长势较好,农艺性状较佳,经济效益高,但石灰施用量为100~120 kg·(667m^(2))^(-1)时,烟草长势差,经济效益低。施用石灰有效降低根茎发病率。石灰施用量为20~60 kg·(667m^(2))^(-1)时,烟叶所含烟碱、总糖、总氮含量及总糖烟碱比、总氮烟碱比达到上等烟标准,而石灰施用量为80~120 kg·(667m^(2))^(-1)时,烟叶化学成分比例不协调,达不到上等烟标准。
The flue-cured tobacco variety K 326 was selected as the research object,and the field test method was used to study the effects of lime addition on the agronomic characteristics,rhizome diseases,economic benefits and quality of flue-cured tobacco.The results showed that when the lime addition amount was 20-40 kg·(667m^(2))^(-1),the flue-cured tobacco grew better,with better agronomic characteristics and high economic benefits,But when the lime application amount was 100-120 kg·(667m^(2))^(-1),the flue-cured tobacco grew poorly and the economic benefits were low.The application of lime effectively reduces the incidence of rhizomes.When the lime application rate was 20-60 kg·(667m^(2))^(-1),the nicotine,total sugar,total nitrogen content,total sugar nicotine ratio and total nitrogen nicotine ratio in tobacco leaves meet the top smoking standards.However,when the lime application rate was 80-120 kg·(667m^(2))^(-1),the chemical composition ratio of the tobacco leaves was inconsistent,and it did not meet the standard of high-quality tobacco.
