为探讨有机无机复合肥对烤烟产质量的影响,采用常规肥料干施和有机无机复合肥大穴环施,以‘K326’为材料,2015年在湖南省浏阳市淳口镇进行了对比试验。结果表明,有机无机复合肥大穴环施,对烤烟生长发育及其生理生化特性指标、烟叶经济性状和产质量有明显促进和提高作用;正常用量有机无机复合肥,移栽30、45、60、75和90 d后根系活力和硝酸还原酶活性最大,移栽60、75和90 d后烟叶净光合速率最大,产量产值最高,分别为2066.15 kg/hm~2和51 393.68元/hm~2。有机无机复合肥大穴环施,有利于促进烤烟生长发育和烟叶经济性状及产质量提高。
In order to investigate the effect of organic-inorganic compound fertilizers on yield and quality of flue-cured tobacco, conventional fertilizers and organic-inorganic compound fertilizers were applied to treat them with “K326” as the material. In 2015, a comparative experiment was conducted in Chunkou Town, Liuyang City, Hunan Province. The results showed that organic-inorganic compound fertilizers applied in a large hole could significantly promote and enhance the growth and development, physiological and biochemical characteristics, economic traits and yield and quality of flue-cured tobacco. The organic-inorganic compound fertilizers normally applied 30, 45, After 75, 90 days, the highest root activity and nitrate reductase activity were obtained. After 60, 75 and 90 d of transplanting, the net photosynthetic rate of tobacco leaves was the highest with the highest yield and yield value of 2066.15 kg / hm 2 and 51 393.68 yuan / hm 2, respectively. Organic-inorganic compound fertilizer can effectively promote the growth and development of flue-cured tobacco and improve the economic traits and yield and quality of tobacco.
