施肥量对烤烟KRK26和K326主要化学成分含量和感官质量的影响
Effect of Fertilizer Application on Main Chemical Components and Sensory Taste Quality of Tobacco Cultivars KRK26 and K326
摘要
Abstract
In a potting experiment with split - split plot design, the effects of nitrogen fertilizer and N/K ratio on the contents of the main chemical components and sensory taste quality of KRK26 and K326 were investigated. The results showed that nitrogen amount had a significant effect on the contents of the chemical components of the two varieties. The total nitrogen content, nicotine, petroleum ether extracts and potassium content increased with increased nitrogen application, but the total sugar and reducing sugar contents reduced. The contents of the total sugar, reducing sugar and potassium in KRK26 were higher than in K326, and the total nitrogen, nicotine and petroleum ether extracts were lower than in K326, the sensory taste quality of KRK26 was superior to that of K326, and their differences in the main chemical components declined with the increment of nitrogen level. The sensory taste quality of KRK26 declined with the increasing of the amount of applied nitrogen, 5 g · stem ‐1 and 7 g · stem ‐1 of applied nitrogen were rational, increase of the amount ( 20 g · stem ‐1 ) of applied K2 0 could improve the sensory taste quality of KRK26 at a low nitrogen level, N/K ra-tio 1:3.0 was rational under the middle nitrogen level.关键词
