摘要
针对河南烟区烟叶浓香型特色下降、土壤板结等问题,于2014年在河南省郾城,以中烟100为材料,进行了腐植酸钾田间试验,研究腐植酸钾对烟田土壤主要营养成分以及烟叶中性致香物质的影响。结果表明,施用腐植酸钾能增加烟田土壤氮磷钾的含量,同时有利于烟叶中性致香物质的生成,其中以常规施肥+150 kg/hm2腐植酸钾的处理效果最好。
In order to improve the characteristic of full aroma of flue-cured tobacco and prevent soil harden in Henan, the test took Zhongyan 100 as material, studied the effect of potassium humate on soil NPK and neutral aroma constituents of flue-cured tobacco in Yancheng. The results showed that the application of potassium humate could improve the content of NPK in soil and in favor of the generation of neutral aroma constituents of flue-cured tobacco, and disposing the fertilizing amount of conventional fertilizing＋150 kg/hm2 had the best result.
